Even experienced artists make marker mistakes. This troubleshooting guide helps you identify, fix, and prevent common marker problems.
Streaking and Uneven Coverage
Causes
- Dried-out marker
- Wrong paper type
- Inconsistent pressure
- Working too slowly
- Partially dried ink
Solutions
For dried markers:
- Store horizontally
- Refill if possible (Copic, etc.)
- Add few drops of rubbing alcohol to revive
For technique issues:
- Work quickly in continuous strokes
- Maintain consistent pressure
- Use proper marker paper
- Don't go over partially dried areas
Use quality markers from our marker guides to minimize issues.
Bleeding and Feathering
Causes
- Wrong paper (too absorbent)
- Too much ink applied
- Going over same area repeatedly
- Paper too thin
Solutions
Prevention:
- Use marker-specific paper (70-100 GSM)
- Apply ink in single, confident strokes
- Let layers dry between applications
- Place barrier sheet under work
If it happens:
- Let dry completely
- Carefully darken surrounding area to match
- Or incorporate into design
- Learn from mistake for next time
See our paper guide for proper surface selection.
Muddy Colors
Causes
- Mixing complementary colors
- Too many layers
- Using dirty colorless blender
- Blending incompatible marker types
Solutions
Color theory approach:
- Blend analogous colors (next to each other on wheel)
- Avoid mixing complements (opposite on wheel)
- Use grays for shadows instead of mixing
- Limit to 2-3 colors per blend
Technical solutions:
- Clean colorless blender on scrap paper between uses
- Don't over-blend
- Let layers dry between applications
Learn more in our color theory guide.
Hard Lines and Visible Strokes
Causes
- Ink dried before blending
- Insufficient overlap
- Wrong blending technique
- Inconsistent pressure
Solutions
Blending technique:
- Work quickly while ink is wet
- Overlap strokes by 50%
- Use flicking motion at edges
- Blend lighter color into darker
For alcohol markers:
- Use colorless blender to soften edges
- Work in small sections
- Blend within 30-60 seconds
Color Contamination
Causes
- Using light marker after dark
- Dirty nibs
- Blending on contaminated paper
- Touching wet ink with different marker
Solutions
Prevention:
- Always work light to dark
- Clean nibs on scrap paper between colors
- Use separate blenders for different color families
- Let areas dry before switching colors
Cleaning contaminated nibs:
- Scribble on scrap paper until clean
- For Copic: remove and clean nib with rubbing alcohol
- Replace nib if severely contaminated (£2-4)
Patchy or Splotchy Results
Causes
- Uneven paper surface
- Inconsistent marker saturation
- Touching wet areas
- Oil from hands on paper
Solutions
Paper preparation:
- Use smooth, quality marker paper
- Don't touch paper surface with hands
- Rest hand on clean scrap paper
- Store paper properly (flat, dry)
Application technique:
- Shake marker before use
- Test on scrap paper first
- Apply in consistent, overlapping strokes
- Don't touch wet ink
Markers Drying Out Too Quickly
Causes
- Improper storage
- Caps not fully closed
- Extreme temperature/humidity
- Old markers
Solutions
Proper storage:
- Store horizontally (prevents ink settling)
- Ensure caps fully closed
- Keep in moderate temperature (15-25°C)
- Avoid direct sunlight
- Control humidity (40-60%)
For refillable markers:
- Refill before completely empty
- Check for cap damage
- Replace worn nibs
See our storage guide for detailed care tips.
Inconsistent Line Width
Causes
- Worn or damaged nib
- Inconsistent pressure
- Wrong nib type for task
- Nib not fully seated
Solutions
Nib maintenance:
- Check for damage or wear
- Replace worn nibs (Copic: £2-4)
- Ensure nib fully inserted
- Clean crushed fibers
Technique:
- Practice consistent pressure
- Use appropriate nib (fine for details, brush for coverage)
- Hold marker at consistent angle
Colors Look Different When Dry
Causes
- Normal for some markers
- Paper absorption affects appearance
- Lighting changes perception
- Layering changes value
Solutions
Test first:
- Create color swatches on actual paper
- Let dry completely before judging
- View in intended lighting
- Note which colors shift most
Adjust technique:
- Go slightly lighter than target
- Build up gradually
- Test blends before using on artwork
Difficulty Scanning Artwork
Causes
- Glossy marker finish
- Bleed-through visible
- Color shifts in scan
- Scanner settings wrong
Solutions
Scanning technique:
- Scan at 300-600 DPI
- Use matte paper when possible
- Adjust scanner settings for markers
- Place black paper behind to hide bleed-through
Post-processing:
- Adjust levels to restore vibrancy
- Correct color shifts
- Remove visible texture
- Clean up edges
Marker Smell Too Strong
Causes
- Alcohol-based markers have strong fumes
- Poor ventilation
- Using many markers at once
- Sensitive to VOCs
Solutions
Ventilation:
- Work near open window
- Use fan for air circulation
- Take regular breaks
- Work in well-ventilated area
Alternative:
- Switch to water-based markers
- Use low-odor alcohol markers
- Wear mask if necessary
Prevention Checklist
Before Starting
- ✓ Test markers on scrap paper
- ✓ Ensure proper paper type
- ✓ Clean work surface
- ✓ Plan color scheme
- ✓ Check marker caps are tight
During Work
- ✓ Work light to dark
- ✓ Blend while wet
- ✓ Let layers dry between applications
- ✓ Clean nibs between colors
- ✓ Use barrier sheet under work
After Finishing
- ✓ Cap all markers immediately
- ✓ Store horizontally
- ✓ Clean work area
- ✓ Note any issues for next time
When to Replace vs Repair
Replace When:
- Non-refillable marker is empty
- Nib is severely damaged
- Marker body is cracked
- Cap no longer seals
Repair When:
- Refillable marker is low (add ink)
- Nib is worn but not damaged (replace nib)
- Marker seems dry (try reviving)
- Minor nib contamination (clean)
Invest in quality, maintainable markers from our Copic guide.
