We’ve all been there: you’ve just printed that crucial report on your inkjet printer, and as you go to highlight a key passage, the neon yellow streak across the page turns into a murky, smudged disaster. The ink bleeds, the text becomes illegible, and your professional document looks like a watercolor gone wrong. It’s a frustration that students, legal professionals, medical staff, and office workers know intimately. But what if I told you that the problem isn’t your printer, your paper, or even your technique—it’s the fundamental chemistry of traditional highlighters meeting the unique composition of inkjet ink?
Enter friction-erasable highlighter technology: a game-changing innovation that uses thermosensitive pigments rather than permanent dyes. These remarkable tools let you lay down vibrant, transparent color that bonds instantly with paper fibers while somehow magically ignoring the water-based inkjet ink sitting on the surface. Even better, the friction-generated heat from the built-in eraser tip makes the pigment disappear cleanly when you need to revise your notes. But not all friction-erasable highlighters are created equal, especially when it comes to the delicate dance with inkjet-printed documents. Let’s dive deep into what makes these tools work, how to evaluate them, and the critical features that separate genuinely smudge-proof performance from marketing hype.

Understanding Friction-Erasable Highlighter Technology
The Science Behind Thermosensitive Ink
Friction-erasable highlighters operate on a fascinating principle of thermochromism. Unlike traditional highlighters that use solvent-based dyes which dissolve and mix with inkjet ink, these modern tools contain microencapsulated pigments that respond to heat. The ink formulation includes leuco dyes—special colorless dyes that become colored when in their stable state but turn clear when heated above a specific temperature threshold, typically around 140°F (60°C). This reaction is purely physical, not chemical, which means it doesn’t interact with your inkjet’s dye-based or pigment-based output.
The microcapsules protect these pigments until pressure and friction from the highlighter’s tip rupture them onto the paper surface. What makes them particularly inkjet-friendly is their rapid-drying, non-penetrating nature. The carrier liquid evaporates within milliseconds, leaving the color particles sitting on top of paper fibers rather than soaking into them—and crucially, not into the inkjet ink layer beneath.
How Friction Activation Works
The eraser mechanism isn’t actually an eraser in the traditional sense. It’s a hard, friction-generating tip—usually made of hardened silicone or specialized plastic—that creates localized heat through rapid rubbing. When you apply sufficient pressure and speed, the temperature in that specific area climbs past the leuco dye’s threshold, triggering the color-to-clear transition. This process is remarkably precise; you’re essentially “switching off” the pigment molecules in that exact spot without disturbing surrounding areas or the underlying print.
Quality matters enormously here. Premium formulations reset completely with minimal effort, while inferior versions may require aggressive rubbing that damages paper fibers or leaves ghostly residues. The best friction-erasable highlighters achieve full erasure with just 2-3 light passes, generating enough heat through friction efficiency rather than user force.
The Inkjet Print Smudging Problem Explained
Why Standard Highlighters Destroy Inkjet Documents
Inkjet printers deposit ink through microscopic nozzles, creating droplets that sit on the paper’s surface. These droplets remain somewhat water-soluble even after drying, especially with dye-based inks common in consumer printers. Traditional highlighters use glycol-based solvents that reactivate these ink droplets on contact. The solvent dissolves both the highlighter dye and the inkjet ink, causing them to merge into that characteristic muddy streak.
Paper type compounds this issue. Standard copy paper has minimal coating, allowing inkjet ink to penetrate slightly and remain vulnerable. Even “inkjet” paper with its porous coating doesn’t fully protect against the aggressive solvents in conventional highlighters. The result is capillary action that draws ink from your printed text into the highlighted path, creating feathery edges and text discoloration that renders documents unprofessional.
The Chemistry of Inkjet Ink vs. Highlighter Ink
Modern inkjet formulations fall into two categories: dye-based and pigment-based. Dye-based inks, used in most home printers, consist of colorants fully dissolved in a water-glycol solution. They’re vibrant but remain permanently water-sensitive. Pigment-based inks, common in office and photo printers, suspend microscopic solid particles that bond to paper surfaces. While more resistant, they’re still vulnerable to the chemical solvents in traditional highlighters.
Friction-erasable inks sidestep this conflict entirely. Their water-free, quick-drying formulation contains no reactivating solvents. The thermosensitive pigments are carried in a volatile base that flashes off immediately, leaving solid particles that don’t interact chemically with either ink type. This chemical neutrality is what makes them genuinely “inkjet-safe” rather than just “smudge-resistant.”
Key Features to Look for in Smudge-Proof Highlighters
Tip Design and Precision
The highlighter tip determines both application accuracy and ink delivery control. Look for chisel tips with defined edge angles—ideally 30-45 degrees—that allow for both broad highlighting (approximately 4-5mm width) and fine underlining (1mm edge). The tip material should be firm enough to maintain its shape but porous enough to deliver consistent ink flow. Premium options use compressed polyester fibers that resist fraying even after hundreds of meters of use.
Tip design also affects the “dry laydown” characteristic crucial for inkjet safety. Poorly engineered tips release too much ink, saturating the paper and increasing smudge risk. Quality tips control flow through capillary channels that regulate release based on writing pressure, preventing pooling at the stroke’s end.
Ink Formulation Quality
Not all thermosensitive inks offer the same performance. Superior formulations provide vibrant color saturation at 40-60% transparency—enough to stand out without obscuring text. They should maintain this intensity for at least 18-24 months under normal office lighting before gradual fading occurs. The pigment particles should be uniformly ground to 5-10 microns, ensuring smooth application without clumping.
The erasability window is another critical factor. Premium inks erase cleanly within 30 seconds to 5 minutes of application, but remain erasable for up to 24 hours. After this period, some binding to paper fibers occurs, making complete removal difficult. The best formulations balance immediate erasability with long-term stability, preventing accidental erasure from casual contact.
Erasability Mechanism Durability
The friction tip’s material composition directly impacts its lifespan and effectiveness. Silicone-based erasers maintain their hardness and friction coefficient through thousands of cycles, while cheaper plastic versions wear down quickly, requiring increasing pressure that damages paper. Look for eraser tips rated for at least 5,000 erasure cycles without significant degradation.
The eraser’s shape also matters. A slightly rounded tip distributes pressure evenly and prevents paper scoring. Some advanced designs incorporate micro-ridges that increase friction efficiency without requiring excessive force, achieving erasure in fewer passes and generating less paper abrasion.
How to Test Highlighter Performance on Your Printer’s Output
The 24-Hour Drying Test
Before trusting any highlighter with important documents, conduct controlled testing. Print a test page with varied text densities: 12-point body text, 10-point footnotes, bold headings, and color graphics. Let it dry for 24 hours in normal office conditions—this ensures the ink has fully cured and reached maximum smudge resistance.
Highlight across different text types using consistent pressure and speed. Wait 10 minutes, then perform a blind “smudge check”: gently rub a clean white cotton swab across the highlighted areas. Any color transfer to the swab indicates insufficient inkjet compatibility. The best performers show zero transfer even under firm pressure.
The Rub Test Methodology
For erasability testing, highlight a 2-inch line across standard text. Immediately attempt erasure using the manufacturer’s recommended technique—typically 3-4 quick, firm strokes. Evaluate the result under magnification: you should see no pigment residue and no paper fiber disturbance. The underlying print should appear untouched, with original contrast intact.
Repeat this test after 1 hour, 6 hours, and 24 hours. Document how erasure quality changes over time. Some formulations perform brilliantly when fresh but leave ghosting after extended periods. For professional use, you need consistent performance across the full timeline.
Color Selection Strategies for Professional Use
Understanding Color Coding Systems
Color choice extends beyond personal preference into cognitive psychology and organizational systems. The “standard four”—yellow, pink, green, and blue—each serve specific purposes. Yellow offers maximum visibility with minimal visual fatigue, making it ideal for general emphasis. Pink draws attention to critical warnings or errors. Green often indicates positive information or completed items. Blue provides a neutral alternative that photocopies clearly.
Advanced users implement tiered systems: bright colors for primary categories, pastels for subcategories. However, thermosensitive technology limits pastel options—true pastels require different pigment chemistry. Most “pastel” friction-erasable highlighters are simply lighter applications of standard colors, achieved through reduced pigment density.
Visibility vs. Aesthetics
Consider your document’s final destination. If scanning or photocopying is likely, test how colors reproduce. Some thermosensitive pigments, particularly lighter blues and greens, may disappear entirely in monochrome copies. Yellow consistently reproduces as light gray, maintaining text visibility. For archival purposes, remember that thermosensitive inks aren’t permanent—while this enables erasure, it also means they’ll gradually fade over years, especially in warm storage conditions.
Tip Styles and Their Applications
Chisel Tips for Broad Highlighting
Standard chisel tips dominate the market for good reason. Their angled design creates 4-5mm wide strokes perfect for covering standard text lines in one pass. The angle determines usability: 30-degree tips offer more precise edge control for fine work, while 45-degree versions prioritize speed for large blocks. Look for tips with reinforced cores that prevent collapse under pressure, a common failure point in budget options.
The ink flow rate should match tip size. Oversaturated chisel tips deposit excess ink that pools at stroke ends, increasing dry time and smudge risk. Quality manufacturers calibrate flow rates to tip dimensions, ensuring even saturation from first to last millimeter of a long highlight stroke.
Fine Tips for Detailed Work
Growing demand for precision has spurred fine-tip friction-erasable highlighters, typically 1-2mm wide. These excel in cramped margins, textbook annotations, and document review where broad highlighting would obscure critical details. The trade-off is ink capacity—fine tips hold significantly less ink, requiring more frequent replacement in heavy-use scenarios.
Fine tips also demand different ink viscosity. Too thick, and flow becomes inconsistent; too thin, and bleeding occurs. Premium fine-tip models use slightly modified formulations with faster evaporation rates to compensate for the reduced surface area, maintaining the same inkjet-safe performance as their broader counterparts.
Dual-Tip Versatility
Some advanced models feature both chisel and fine tips in one body, offering maximum flexibility. The engineering challenge is preventing ink migration between the two reservoirs. Quality designs use separate internal channels and valve systems, ensuring each tip maintains its optimized flow characteristics. While convenient, these models typically cost 30-40% more than single-tip equivalents and may have slightly reduced overall ink capacity.
Understanding Dry Time and Settling Periods
Immediate Use vs. 24-Hour Cure Time
Friction-erasable highlighters dry to the touch within 2-5 seconds, but the full curing process takes longer. During the first 30 minutes, the thermosensitive pigments continue binding to paper fibers. Erasing within this window requires minimal effort. After 24 hours, the bond strengthens significantly—still erasable, but requiring more friction and potentially leaving microscopic pigment traces.
For critical documents, adopt a “highlight today, review tomorrow” workflow. This allows you to make initial passes while ideas are fresh, then revisit with the option to erase and refine after the ink has fully settled. This approach also reveals any latent smudging issues that might not be immediately apparent.
Environmental Factors Affecting Performance
Humidity dramatically impacts performance. In environments above 60% relative humidity, the thermosensitive ink’s carrier liquid evaporates more slowly, extending the vulnerable smudge window. Conversely, very dry conditions (below 30% RH) can cause the ink to set too quickly, making immediate erasure difficult. The sweet spot is 40-50% RH at 68-72°F (20-22°C).
Paper temperature also matters. Freshly printed pages from a warm printer (common after long print jobs) retain heat that can prematurely activate the thermosensitive pigments, reducing color intensity. Let pages cool to room temperature before highlighting for optimal results.
Price Tiers and What They Indicate About Quality
Budget-Friendly Options ($5-$10 per set)
Entry-level friction-erasable highlighters typically offer basic thermosensitive technology but cut corners on tip durability and ink consistency. You’ll find limited color options—usually just 4-6 basics—and eraser tips that may wear out after 1,000-2,000 cycles. Ink formulations in this range often use larger pigment particles (15+ microns), resulting in slightly grainy application and potential clogging.
These can be suitable for light student use or non-critical applications. However, they frequently fail the 24-hour erasure test, leaving ghosting that’s unacceptable for professional documents. Tip fraying is common after 2-3 weeks of daily use, compromising precision.
Mid-Range Performance ($10-$20 per set)
This sweet spot delivers professional-grade performance for most users. Expect 8-12 color options, silicone eraser tips rated for 5,000+ cycles, and micro-milled pigments under 10 microns. Manufacturers in this tier invest in flow control engineering, resulting in consistent laydown and reliable inkjet compatibility.
Mid-range models typically include features like clip-on caps with airtight seals, preventing tip dry-out during storage. Ink capacity averages 400-500 meters of highlighting per pen, sufficient for 3-6 months of regular use. The erasure mechanism provides consistent performance across the full 24-hour window, making these ideal for law offices, medical practices, and academic research.
Premium Professional Grade ($20+ per set)
Top-tier options justify their price through specialized formulations and construction. These use sub-5-micron pigments for glass-smooth application and incorporate UV stabilizers that extend color life to 3-5 years. Eraser tips often feature advanced friction-enhancing textures and are rated for 10,000+ cycles.
Premium models may offer refillable systems, reducing long-term cost and environmental impact. Some include archival-quality certifications indicating minimal acid content and paper interaction. For professionals handling sensitive legal or medical documents where permanent alteration is unacceptable, this tier provides the reliability and consistency that cheaper alternatives cannot match.
Environmental and Safety Considerations
Non-Toxic Certifications to Look For
While most friction-erasable highlighters are water-based and non-toxic, certifications provide assurance. Look for ACMI “AP” (Approved Product) seals indicating non-toxicity per ASTM D-4236 standards. For European users, CE marking and compliance with EN 71-3 (toy safety standards for chemical migration) indicate rigorous testing.
Medical and educational environments should prioritize products certified explicitly for use by children under 12, as these undergo additional scrutiny for heavy metals and endocrine disruptors. The thermosensitive pigments themselves are generally inert, but the carrier liquids and tip materials can contain trace compounds worth investigating for sensitive applications.
Recyclable Components
Sustainability varies widely. Most barrels are polypropylene (recycling code #5), but caps and clips may be different plastics that complicate recycling. Premium brands increasingly offer take-back programs where you return spent pens for manufacturer recycling. Refillable models reduce plastic waste by 60-70% over disposable equivalents.
Consider ink depletion rates. Higher-quality pens with better flow control use ink more efficiently, meaning fewer replacements over time. A pen that lasts 500 meters versus one that lasts 300 meters represents a 40% reduction in long-term waste, even if the initial plastic content is similar.
Compatibility Beyond Inkjet: Laser, Gel, and Ballpoint
Cross-Media Performance Testing
While our focus is inkjet prints, true versatility means performing across all document types. Laser prints, fused to paper at 400°F, are inherently smudge-proof but can still be affected by highlighter solvents. Friction-erasable inks work beautifully here, often providing even cleaner erasability since the underlying text is completely stable.
Gel pens present a unique challenge—some gel inks contain thermosensitive components themselves. Test thoroughly: apply gel ink, let dry 24 hours, then highlight and attempt erasure. Quality friction-erasable highlighters won’t disturb the gel ink, but budget versions might cause feathering. Ballpoint ink is generally the most compatible due to its oil-based, quick-drying nature.
When Friction-Erasable Isn’t the Best Choice
For permanent archival highlighting that must last decades, traditional pigment-based highlighters remain superior. Thermosensitive pigments will gradually fade over 5-10 years, even without erasure. Documents stored in warm environments (above 85°F) may experience premature fading. For historical archives, legal permanent records, or anything requiring indefinite preservation, consider archival-quality permanent highlighters or digital annotation instead.
Storage and Maintenance Best Practices
Temperature Sensitivity Issues
Remember: these are thermosensitive tools. Storage above 120°F (in a hot car, near radiators, or in direct sunlight) can partially erase your highlights or even deactivate the ink within the pen. Conversely, freezing temperatures can cause the carrier liquid to separate from pigments, permanently damaging the formulation. The ideal storage range is 50-80°F.
For long-term storage, keep pens horizontal. Vertical storage (tip-down) can cause pigment settling that clogs the feed system. If pens have been unused for 3+ months, gently shake them and make a few test strokes on scrap paper to redistribute pigments before using on important documents.
Cap Sealing Mechanisms
Air exposure is the enemy of consistent flow. Look for caps with inner sealing rings that create an airtight lock when clicked. The “click” should feel firm and require deliberate force to remove. Loose-fitting caps allow the volatile carrier to evaporate, thickening the ink and eventually rendering the pen unusable.
Test cap effectiveness: cap a pen, then submerge the tip in water for 30 seconds. Remove and uncap—any water inside indicates a poor seal. Quality caps keep the tip environment stable for 6-12 months between uses, while inferior seals may fail within weeks.
Common User Errors and How to Avoid Them
Over-Highlighting and Paper Damage
The most frequent mistake is treating friction-erasable highlighters like their permanent counterparts. Excessive pressure doesn’t increase color intensity—it damages paper fibers and can cause premature erasure through friction heating. Use light, consistent pressure and let the ink’s transparency work for you. Multiple light passes are better than one heavy stroke.
Over-highlighting spatially is equally problematic. Extending highlights more than 2-3mm beyond text edges wastes ink and increases accidental erasure risk when your hand rubs previously highlighted areas. Train yourself to highlight with precision, treating the tool like a scalpel rather than a paintbrush.
Incomplete Erasure Techniques
Many users erase incorrectly, using slow, heavy pressure that scores paper without generating sufficient heat. The optimal technique is 3-4 rapid, firm strokes covering the entire highlight area. Speed generates friction heat more effectively than pressure. Use the eraser tip’s full width, not just its edge, to distribute heat evenly.
Another error is erasing before the ink fully dries. While friction-erasable inks dry quickly, immediate erasure (within 10 seconds) can push wet pigment into paper fibers, creating permanent ghosting. Wait at least 30 seconds after highlighting before attempting erasure for cleanest results.
Professional vs. Academic Applications
Legal Document Review Standards
Legal professionals require absolute reliability. Many jurisdictions accept friction-erasable highlights on working copies but prohibit them on court-submitted originals. Always verify local rules. For deposition preparation and internal review, these tools are invaluable—allowing color-coded emphasis that can be modified as case strategy evolves.
Implement a color protocol: yellow for witness statements, pink for contradictory evidence, green for supporting case law. The erasability feature lets you reclassify information as discovery progresses. However, never use these on original signed documents or anything requiring permanent markup. Keep a log of your color-coding system for team consistency.
Medical Record Highlighting Protocols
Healthcare settings demand precision and often involve frequent information updates. Friction-erasable highlighters excel for patient chart reviews, allowing clinicians to flag critical values, medication changes, or follow-up items that may need adjustment as conditions evolve. The non-toxic formulations are generally safe for clinical environments.
Critical consideration: never highlight directly over medication orders or numerical values. Highlight adjacent to critical information, not over it, preserving absolute legibility. Many hospitals require a “no-highlight-over-text” policy regardless of highlighter type, making the precision tip design even more important for margin-based annotation.
Student Study Guide Optimization
Students benefit most from the iterative learning process these tools enable. First-pass highlighting during initial reading can be refined after lectures or further study. The ability to erase and reorganize emphasis patterns transforms static textbooks into dynamic learning tools. Create a personal system: initial highlights in yellow, lecture additions in pink, exam-priority items in green.
For textbook resale, friction-erasable inks are essential. Complete erasure leaves pages virtually untouched, preserving book value. However, check publisher policies—some digital rights management for rented textbooks prohibits any marking, even erasable. When in doubt, highlight on separate sticky notes rather than directly on pages.
Troubleshooting Performance Issues
When Erasing Leaves Residue
Ghosting after erasure indicates either low-quality pigments or improper technique. First, verify you’re using sufficient speed—slow rubbing generates heat inefficiently. If technique is correct, the pigment particles may be too large or poorly encapsulated. Switch to a higher-quality option with sub-10-micron particle size.
Paper quality also contributes. Highly porous papers trap pigment deeper in fibers, making complete removal difficult. If ghosting persists across multiple highlighter brands, switch to smoother, higher-weight paper (24lb vs. standard 20lb) for critical documents. This provides a less fibrous surface for pigment adhesion.
Dealing with Faded Highlights Over Time
Gradual fading over months is inherent to thermosensitive technology, but premature fading indicates temperature exposure or formulation issues. Store highlighted documents in cool, stable environments away from direct sunlight. For long-term reference, consider scanning highlighted pages within 2-3 weeks of marking to preserve the color-coded information digitally.
If fading occurs within days without obvious heat exposure, the ink formulation likely lacks UV stabilizers. This is common in budget options. Upgrade to mid-range or premium models that explicitly advertise “extended color life” or “UV-resistant formulation.” These include additives that stabilize the leuco dyes against gradual environmental activation.
Making Your Final Selection: A Decision Framework
Assessing Your Primary Use Case
Start by honestly evaluating your needs. Heavy daily users (legal assistants, medical reviewers) should invest in premium, refillable models with proven durability. Light, occasional users (home office, casual students) can achieve satisfactory results with mid-range options. Budget-tier products are suitable only for non-critical, high-volume disposable use where perfect erasure isn’t essential.
Calculate your cost-per-meter: a $15 pen lasting 500 meters costs $0.03 per meter, while a $5 pen lasting 150 meters costs $0.033 per meter plus replacement time. For professionals, the reliability premium of higher-end models often outweighs minimal per-unit savings.
Creating a Personal Testing Checklist
Before committing to any highlighter, conduct these tests:
- Inkjet smudge test on your specific printer’s output
- 24-hour erasure quality assessment
- Tip durability test: highlight 50 continuous meters and check for fraying
- Cap seal water submersion test
- Temperature resilience: leave highlighted sample in warm car for 4 hours, check for fading
Document results and repeat with 2-3 top contenders. The small time investment prevents costly bulk purchases of unsuitable tools. Remember, the “best” highlighter is the one that performs flawlessly with your specific printer, paper, and workflow—not necessarily the most expensive or popular option.
Frequently Asked Questions
Do friction-erasable highlighters really never smudge inkjet prints?
While no product can claim absolute perfection, quality friction-erasable highlighters are engineered specifically to avoid chemical interaction with inkjet inks. They dry instantly and don’t contain solvents that reactivate printer ink. However, “never” depends on factors like paper type, ink drying time, and application pressure. Always test on your specific printer-paper combination before using on critical documents.
How long do I need to wait after printing before it’s safe to highlight?
For standard dye-based inkjet prints, wait a minimum of 30 seconds for the surface to feel dry to the touch. However, for maximum smudge protection, allow 5-10 minutes for the ink to fully set. For pigment-based inks or photo papers, 15-30 minutes is safer. The 24-hour test is only necessary for evaluating highlighter quality, not for normal use.
Will my highlights disappear if I leave my document in a hot car?
Potentially, yes. Thermosensitive pigments begin activating around 140°F (60°C), and vehicle interiors can exceed this in summer. While brief exposure may only cause partial fading, extended heat can erase highlights completely. Always store highlighted documents at room temperature. For important papers, scan them to preserve the color-coded information.
Can I use friction-erasable highlighters on both sides of thin paper?
Generally, yes—these inks sit on the surface rather than soaking through. However, heavy-handed pressure can cause indentation that shows through. On paper below 20lb weight, test first by highlighting one side, then checking the reverse for any bleed-through or show-through. Use lighter pressure and consider single-sided highlighting on very thin paper.
Why does my eraser tip sometimes leave dark marks instead of erasing?
This occurs when the eraser becomes clogged with pigment residue. Clean it by rubbing vigorously on clean scrap paper until the marks disappear. If cleaning doesn’t help, the eraser material may be too soft or worn. Replace the pen or, in some premium models, replace just the eraser tip. Using excessive pressure can also embed eraser material into paper fibers, creating permanent marks.
Are these highlighters safe for children to use?
Most friction-erasable highlighters carry non-toxic certifications and are safer than permanent markers. However, they contain small parts (caps, eraser tips) that pose choking hazards for children under 3. The thermosensitive pigments are inert but shouldn’t be ingested. For school use, choose products specifically certified for children under ASTM D-4236 and supervise younger users.
How do I know when my highlighter is running out of ink?
Unlike traditional highlighters that gradually fade, friction-erasable models often maintain color intensity until nearly empty, then stop abruptly. Warning signs include inconsistent flow requiring multiple passes, the tip feeling “scratchy” due to inadequate lubrication, and the eraser requiring more friction to work. Keep a backup when you notice these symptoms.
Can I refill friction-erasable highlighters?
Some premium models offer refillable systems, but most are disposable. Refillable options typically cost 30-50% more initially but reduce long-term expense and waste. Check the manufacturer’s website for refill availability before purchasing. Refills must match the exact formulation—using incorrect ink can clog the feed system or compromise erasability.
Will these highlighters work on glossy or coated inkjet paper?
Glossy papers present challenges. The non-porous coating prevents proper pigment adhesion, causing beading and poor erasability. While some highlighters perform adequately on lightly coated “presentation” papers, heavily glossy photo papers are problematic. For best results, stick to matte or semi-matte inkjet papers. If you must highlight on glossy surfaces, test extensively first.
Do friction-erasable highlights scan or copy clearly?
Yes, generally better than permanent highlights. Because the pigments sit on the surface and maintain consistent transparency, they reproduce as clean, light gray tones in monochrome copies. Yellow typically copies as the lightest, most readable shade. However, some light colors (pale blue, mint green) may disappear entirely in copies. Always test copy/scan quality with your specific color choices before relying on them for document routing.
