Color Management
Analyze and manage colors in your documents for consistent output.
Why Color Management Matters
Different devices display colors differently:
- Monitors use RGB (Red, Green, Blue)
- Printers use CMYK (Cyan, Magenta, Yellow, Black)
- Colors can shift between devices without proper management
Professional printing requires careful color management to ensure output matches expectations.
Color Spaces
RGB
Red, Green, Blue - Additive color for screens:
- Web graphics
- Digital display
- Email documents
CMYK
Cyan, Magenta, Yellow, Black - Subtractive color for printing:
- Commercial printing
- Offset presses
- Professional output
Spot Colors
Named colors (e.g., Pantone) for exact color matching:
- Brand colors
- Special inks (metallic, fluorescent)
- Precise color requirements
Grayscale
Single-channel black and white:
- Black and white printing
- Newspaper production
- Cost-effective printing

Color Analysis Report
Overview Section
| Metric | Description |
|---|---|
| Total colors | Number of distinct colors |
| RGB objects | Count of RGB-colored elements |
| CMYK objects | Count of CMYK-colored elements |
| Spot colors | Named spot colors used |
| Grayscale objects | Black/white elements |
Color List
For each color:
- Color space (RGB, CMYK, Spot)
- Color values (e.g., C:100 M:50 Y:0 K:0)
- Where it’s used (text, images, shapes)
- Page locations
Problem Detection
Issues automatically flagged:
- RGB colors in print documents
- Unregistered spot colors
- Rich black exceeding limits
- High ink coverage
Ink Coverage Analysis
What is Ink Coverage?
Total Ink Coverage (TIC) is the sum of all CMYK values:
- C:100 + M:100 + Y:100 + K:100 = 400%
- Most printing processes limit TIC to 240-320%
Checking Ink Coverage
- Click Tools → Print Production → Ink Coverage
- Set the maximum allowed (typically 300%)
- View areas that exceed the limit
- Areas are highlighted on the document
Ink Coverage Limits
| Output Type | Typical Limit |
|---|---|
| Coated paper | 300-340% |
| Uncoated paper | 260-300% |
| Newsprint | 240-260% |
| Web offset | 260-300% |
Exceeding ink coverage limits can cause printing problems: slow drying, smearing, show-through, and color shifts.
Converting Colors
RGB to CMYK
Select Conversion
Click Tools → Print Production → Convert Colors
Choose Color Space
Select Convert to CMYK
Select Profile
Choose output profile:
- SWOP (US standard)
- FOGRA39 (European coated)
- Custom ICC profile
Set Options
- Convert images
- Convert vectors
- Convert text
- Preserve black
Convert
Click Convert to process
CMYK to RGB
For documents going to screen:
- Select Convert to RGB
- Choose sRGB or other RGB profile
- Convert
Spot to CMYK
Convert spot colors to CMYK process colors:
- Select the spot color to convert
- Click Convert to CMYK
- Review the CMYK equivalent
- Apply conversion
Spot colors converted to CMYK may not match exactly. For critical brand colors, keep spot colors and specify them to the printer.
Rich Black
What is Rich Black?
Rich black uses CMYK inks together to create deeper black than black ink alone.
Standard Rich Black Recipes
| Recipe | Values | Use Case |
|---|---|---|
| Cool rich black | C:60 M:40 Y:40 K:100 | Most common |
| Warm rich black | C:40 M:60 Y:60 K:100 | Warmer tone |
| Designer black | C:70 M:50 Y:30 K:100 | Deep, rich tone |
| Pure black | C:0 M:0 Y:0 K:100 | Text, thin lines |
When to Use Rich Black
- Large black areas
- Backgrounds
- Bold headings
When NOT to Use Rich Black
- Body text (use pure black K:100)
- Thin lines (registration issues)
- Small elements
ICC Profiles
What are ICC Profiles?
ICC profiles describe how devices reproduce color. They enable accurate color conversion.
Common Profiles
| Profile | Region/Use |
|---|---|
| SWOP v2 | US coated printing |
| GRACoL | US commercial printing |
| FOGRA39 | Europe coated |
| FOGRA47 | Europe uncoated |
| sRGB | Standard web/screen |
| Adobe RGB | Photography |
Embedding Profiles
- Go to File → Document Properties → Color
- Select output intent profile
- Click Embed Profile
Color Space Problems
RGB in Print Documents
Problem: RGB colors may print differently than expected
Solution: Convert to CMYK with appropriate profile
Spot Color Mismatch
Problem: Spot color not available at printer
Solution: Provide color values or convert to CMYK
High Ink Coverage
Problem: Areas exceed ink limits
Solution: Reduce saturation or use richer black alternatives
Missing Profile
Problem: Document has no embedded profile
Solution: Assign or embed appropriate profile
Best Practices
- Know your output: Design in the appropriate color space
- Embed profiles: Always include color profile information
- Check ink coverage: Verify before sending to print
- Preserve black text: Don’t convert pure black text
- Soft proof: Preview how colors will print
Soft Proofing
Preview how your document will look when printed:
- Click View → Soft Proof
- Select output profile
- View simulated output
- Adjust colors if needed
Tips
- Convert to CMYK early in your workflow
- Use pure black (K:100) for body text
- Rich black for large areas only
- Always embed ICC profiles
- Verify ink coverage before printing
- Keep original RGB files for screen use
Next Steps
