# Color Accuracy Guide

> Achieve accurate, predictable colors in print

## Understanding the Challenge

**The fundamental problem**: Your screen uses light (RGB), printers use ink (CMYK). They can't show the same colors.

<Warning>
  **Critical Truth**: Your screen will NEVER show exact print colors. Accept this, plan for it, work with it.
</Warning>

## Why Colors Shift

### The RGB/CMYK Gap

<Tabs>
  <Tab title="RGB (Screen)">
    **How it works**: Additive color (adds light)

    **Colors**: Red + Green + Blue light

    **Gamut**: Wide range of colors

    **Brightest**: Pure light = very bright colors

    **Example**: Neon blues, bright greens, vivid oranges

    **Your monitor**: Shows RGB
  </Tab>

  <Tab title="CMYK (Print)">
    **How it works**: Subtractive color (absorbs light)

    **Inks**: Cyan + Magenta + Yellow + Black

    **Gamut**: Narrower range

    **Limitation**: Can't recreate brightest RGB colors

    **Example**: Bright blue → Becomes duller in print

    **Your printer**: Uses CMYK
  </Tab>

  <Tab title="The Gap">
    **Visual representation**:

    ```
    RGB Gamut (what you see):
    ┌────────────────────┐
    │   Wider range      │
    │  ┌──────────────┐  │ ← These colors
    │  │ CMYK Gamut   │  │   can't be printed!
    │  │              │  │
    │  └──────────────┘  │
    └────────────────────┘
    ```

    **Result**: Some screen colors impossible to print

    **Shift amount**: Varies by color

    * Blues: Significant shift
    * Greens: Moderate shift
    * Reds: Slight shift
    * Neutrals: Minimal shift
  </Tab>
</Tabs>

### Other Factors

<AccordionGroup>
  <Accordion title="Monitor Calibration" icon="desktop">
    **Your monitor may be**:

    * Too bright
    * Too saturated
    * Wrong color temperature
    * Not calibrated

    **Result**: You see incorrect colors

    **Impact**: Design looks different than reality

    **Solution**: Monitor calibration (if serious about color)
  </Accordion>

  <Accordion title="Paper Type" icon="file">
    **Different papers = Different results**:

    **Coated (glossy/matte)**:

    * Brighter colors
    * Less ink absorption
    * More vibrant

    **Uncoated (natural)**:

    * Duller colors
    * More ink absorption
    * Softer appearance

    **Same ink, different paper** = Different color

    **Match**: ICC profile to paper type
  </Accordion>

  <Accordion title="Lighting Conditions" icon="lightbulb">
    **Viewing conditions matter**:

    **Daylight**: Colors appear different
    **Fluorescent**: Cool, blue-ish cast

    **Practical**: View in same lighting as final use
  </Accordion>

  <Accordion title="Ink & Press Variation" icon="print">
    **Variables**:

    * Printer calibration
    * Ink batch
    * Press operator
    * Humidity, temperature

    **Result**: Slight variation run-to-run

    **Normal**: ±5% color variation

    **Critical work**: Use spot colors (Pantone)
  </Accordion>
</AccordionGroup>

## Strategies for Color Accuracy

### Strategy 1: Design CMYK-Friendly

<Steps>
  <Step title="Know Problem Colors">
    **Avoid or adjust**:

    **Very difficult to print**:

    * Neon/fluorescent colors
    * Bright electric blue (RGB 0,100,255)
    * Vivid lime green (RGB 0,255,0)
    * Intense orange (RGB 255,100,0)

    **Why**: Outside CMYK gamut

    **Solution**: Use more muted versions or spot colors
  </Step>

  <Step title="Use CMYK Color Picker">
    **In Figma**: Use HEX/RGB but think CMYK

    **External tools**:

    * Adobe Color
    * Coolors.co (CMYK mode)
    * Pantone Color Finder

    **Pick colors**: Within CMYK gamut

    **Result**: Less shift when converting
  </Step>

  <Step title="Test Early">
    **Don't wait until final**:

    1. Design in RGB
    2. Convert to CMYK early (Printery preview)
    3. See how colors shift
    4. Adjust if needed
    5. Continue designing

    **Benefit**: No surprises at end
  </Step>

  <Step title="Embrace Limitations">
    **Accept**: Print won't be as vibrant as screen

    **Design for print**: Not screen

    **Tip**: Design in slightly higher saturation

    * Accounts for CMYK dulling
    * But don't go extreme

    **Balance**: Between screen and print reality
  </Step>
</Steps>

### Strategy 2: Use Correct ICC Profile

<Tabs>
  <Tab title="Ask Your Printer">
    **Best source**: Your chosen print shop

    **Question**: "What ICC profile should I use?"

    **They'll specify**:

    * Profile name (e.g., ISO Coated v2)
    * Or provide custom .icc file

    **Use exactly**: What they recommend

    ✅ **Most reliable approach**
  </Tab>

  <Tab title="Standard Profiles">
    **If printer doesn't specify**:

    **Europe/Global**: ISO Coated v2 300%

    * Works \~90% of the time
    * Industry standard

    **USA**: US Web Coated (SWOP) v2

    * American standard
    * Magazines, commercial

    **Uncoated paper**: PSO Uncoated ISO 12647

    * For natural stock

    **See**: [ICC Profiles Guide](/color/icc-profiles)
  </Tab>

  <Tab title="Custom Profiles">
    **When provided**:

    * Specialty printer
    * Unique substrate
    * Color-critical work

    **Upload to Printery** (Pro):

    1. Get .icc file from printer
    2. Color tab → Upload Custom Profile
    3. Select from dropdown

    **Most accurate**: For that specific press
  </Tab>
</Tabs>

### Strategy 3: Use Pantone for Critical Colors

<Tabs>
  <Tab title="When to Use Spot Colors">
    **Brand colors**: Logo, brand identity

    **Out-of-gamut colors**: Bright colors CMYK can't match

    **Consistency**: Same color every time

    **Example**:

    ```
    Logo: Pantone 2925 C (brand blue)
    vs.
    CMYK approximation: C100 M50 Y0 K0 (close but varies)
    ```

    **Cost**: Additional plate, but worth it

    **See**: [Spot Colors Guide](/color/spot-colors)
  </Tab>

  <Tab title="How to Specify">
    **Get Pantone number** from:

    * Brand guidelines
    * Physical Pantone book
    * Pantone.com color finder

    **Example**: "Pantone 185 C" (Coca-Cola red)

    **Specify**:

    * Coated (C) for glossy paper
    * Uncoated (U) for matte paper

    **Important**: C and U are different colors!
  </Tab>

  <Tab title="Add to Design">
    **In Printery**:

    1. Color tab → Add Spot Color
    2. Enter Pantone number or choose from library
    3. Map to RGB color in design
    4. Export includes spot color plate

    **Result**: Exact color match, every time

    **Pro feature**: Requires Pro subscription
  </Tab>
</Tabs>

### Strategy 4: Order Physical Proofs

<Steps>
  <Step title="Why Physical Proofs Matter">
    **Screen preview**: Approximate at best

    **Physical proof**: Truth

    **Shows**:

    * Actual printed colors
    * Paper texture effect
    * Finish (gloss/matte)
    * Quality

    **Cost**: \$10-100 depending on project

    **Worth it**: Prevents \$1000+ mistakes
  </Step>

  <Step title="Types of Proofs">
    **Digital proof (free)**:

    * PDF review on screen
    * Checks layout, text
    * Color NOT accurate

    **Inkjet proof (\$10-30)**:

    * Desktop inkjet printer
    * Somewhat close to final
    * Different inks/paper

    **Press proof (\$50-200)**:

    * Actual press, actual paper
    * Most accurate
    * Expensive but exact

    **Online services (\$20-50)**:

    * Many printers offer proof option
    * Good middle ground
  </Step>

  <Step title="What to Check">
    **When proof arrives**:

    **Colors**:

    * Close to expectations?
    * Acceptable shifts?
    * Any surprises?

    **Quality**:

    * Text sharp?
    * Images clear?
    * No defects?

    **Layout**:

    * Everything positioned correctly?
    * Nothing cut off?
    * Bleed adequate?

    **Approve or Adjust**: Based on proof
  </Step>

  <Step title="Making Adjustments">
    **If colors off**:

    1. Note which colors need adjustment
    2. Adjust in Figma (more/less saturation)
    3. Re-export
    4. Order new proof
    5. Repeat until satisfied

    **Common adjustments**:

    * Blues: Often need more saturation in design
    * Reds: Usually close, minor tweaks
    * Greens: May need adjustment
    * Black: Check if rich black needed
  </Step>
</Steps>

### Strategy 5: Soft Proofing

<Tabs>
  <Tab title="What is Soft Proofing?">
    **Definition**: Simulating print colors on screen

    **How**: Using ICC profiles + software

    **Tools**:

    * Adobe Acrobat Pro
    * Adobe Photoshop
    * Some other apps

    **Limitation**: Still screen, not perfect

    **Benefit**: Better than nothing
  </Tab>

  <Tab title="In Adobe Acrobat">
    **Steps**:

    1. Open PDF in Acrobat Pro
    2. View → Proof Setup → Custom
    3. Select ICC profile (e.g., ISO Coated v2)
    4. Enable "Simulate Paper Color"
    5. View changes

    **What you see**: Approximation of CMYK result

    **More realistic**: Than straight RGB view

    **Still approximate**: Monitor limitations apply
  </Tab>

  <Tab title="In Printery">
    **Preview feature** (if available):

    * Color tab → Preview CMYK
    * Side-by-side comparison
    * Shows expected shift

    **Helps**: Identify major issues early

    **Use**: Before exporting final PDF
  </Tab>
</Tabs>

## Monitor Calibration

### For Serious Color Work

<AccordionGroup>
  <Accordion title="Why Calibrate?" icon="desktop">
    **Uncalibrated monitors**:

    * Too bright/dark
    * Wrong colors
    * Inconsistent

    **Result**: Designing blind

    **Calibrated monitor**:

    * Accurate colors
    * Correct brightness
    * Industry standard

    **Impact**: Design what you intend
  </Accordion>

  <Accordion title="Calibration Tools" icon="wrench">
    **Hardware calibrators** (recommended):

    * X-Rite i1Display Pro (\$200-300)
    * Datacolor SpyderX (\$150-250)
    * X-Rite ColorMunki (\$100-200)

    **How they work**:

    * Sensor measures screen output
    * Software creates profile
    * Corrects monitor colors

    **Frequency**: Monthly or quarterly

    **Worth it**: For professional work
  </Accordion>

  <Accordion title="Manual Calibration" icon="sliders">
    **Free but less accurate**:

    **Steps**:

    1. Let monitor warm up (30 min)
    2. Set brightness: \~120 cd/m²
    3. Adjust color temperature: 6500K (D65)
    4. Use system calibration:
       * Mac: System Preferences → Displays → Color → Calibrate
       * Windows: Display settings → Calibrate

    **Limitation**: Subjective, not precise

    **Better than**: Nothing
  </Accordion>

  <Accordion title="Viewing Conditions" icon="lightbulb">
    **For accurate assessment**:

    **Lighting**:

    * Neutral (not colored)
    * Consistent brightness
    * Avoid glare on screen

    **Ideal**: D50 viewing booth (pro studios)

    **Practical**: Controlled office lighting

    **Avoid**: Direct sunlight, colored walls
  </Accordion>
</AccordionGroup>

## Common Color Issues & Solutions

### Issue 1: Blues Too Dull

**Problem**: Bright blue on screen → Muddy blue in print

**Why**: Blue is outside CMYK gamut

**Solutions**:

1. **Accept**: Some dulling is inevitable
2. **Design with duller blue**: Closer to CMYK limit
3. **Use Pantone**: Exact blue (Pantone 2925 C, etc.)
4. **Increase saturation in design**: Compensate for loss

**Test**: Convert to CMYK preview early

***

### Issue 2: Colors Look Different Per Print Run

**Problem**: First batch different from second batch

**Why**: Ink variation, press calibration, humidity

**Normal**: ±5% variation is industry standard

**Solutions**:

1. **Accept variation**: If minor
2. **Use Pantone**: More consistent
3. **Specify tolerance**: With printer (+/- range)
4. **Order extra**: First run, avoid re-orders

**Critical work**: Spot colors only

***

### Issue 3: Black Looks Weak

**Problem**: Black not deep enough

**Why**: Using pure black (K100 only)

**Solutions**:

1. **Use rich black**: C60 M40 Y40 K100
2. **Printery**: Auto rich black setting
3. **Specify**: Rich black for large areas

**When to use**:

* Backgrounds: Rich black
* Text: Pure black (K100)

**See**: [Black Handling Guide](/color/black-handling)

***

### Issue 4: Gradients Have Banding

**Problem**: Smooth gradient on screen → Visible steps in print

**Why**:

* Not enough color steps
* Compression too high
* Short gradient distance

**Solutions**:

1. **Longer gradients**: More space = smoother
2. **More color steps**: Increase DPI
3. **Lower compression**: 95% vs 85%
4. **Add noise**: 1-2% noise masks banding
5. **Use spot varnish**: Overlay gloss effect

**Test**: Physical proof before bulk

***

### Issue 5: White Looks Cream/Yellow

**Problem**: White background prints yellowish

**Why**:

* Paper natural color (not pure white)
* Uncoated paper (more yellow)
* Lighting conditions

**Solutions**:

1. **Choose brighter paper**: Premium white stock
2. **Coated vs uncoated**: Coated whiter
3. **Design choice**: Embrace natural paper tone
4. **White ink**: Special (rare, expensive)

**Reality**: Paper white ≠ screen white
