# ICC Profiles Guide

> Choose the right ICC profile for perfect color reproduction

## What Are ICC Profiles?

ICC (International Color Consortium) profiles are standardized files that define how colors should be interpreted and converted between different devices and printing conditions.

<Note>
  Think of ICC profiles as **translation dictionaries** between different color languages (RGB screen vs CMYK print).
</Note>

## How ICC Profiles Work

```
Your Design (RGB colors)
         ↓
ICC Profile (translation rules)
         ↓
Printer Output (CMYK colors)
```

Each profile contains:

* **Color space definition**: What colors can be reproduced
* **Conversion rules**: How to map RGB to CMYK
* **Rendering intents**: How to handle out-of-gamut colors
* **Black generation**: How to create blacks (GCR/UCR)

## Common ICC Profiles

## How to Choose the Right Profile

### Decision Tree

<Steps>
  <Step title="1. Ask Your Printer">
    **Best approach**: Contact your printer and ask:

    * "What ICC profile do you recommend?"
    * "What's your standard color profile?"

    Most professional printers will specify their preferred profile.
  </Step>

  <Step title="2. Check Your Region">
    If printer doesn't specify:

    * **Europe/Global**: ISO Coated v2 300%
    * **United States**: US Web Coated (SWOP) v2 or GRACoL
    * **Asia/Japan**: Japan Color 2001
  </Step>

  <Step title="3. Consider Paper Type">
    * **Coated paper** (shiny/matte): Use coated profile
    * **Uncoated paper** (textured/natural): Use uncoated profile
    * **Not sure?** Coated is most common for marketing materials
  </Step>

  <Step title="4. Match Printing Method">
    * **Offset printing**: Standard ICC profiles
    * **Digital printing**: Ask printer (may have custom profile)
    * **Web press**: SWOP profiles
    * **Sheet-fed**: GRACoL or ISO Coated
  </Step>
</Steps>

## Setting ICC Profile in Printery

<Steps>
  <Step title="Open Plugin">
    Select your frame and launch Printery
  </Step>

  <Step title="Go to Color Tab">
    Click the "Color" tab in the plugin interface
  </Step>

  <Step title="Enable CMYK Conversion">
    Check "Convert to CMYK"
  </Step>

    Custom profile now appears in dropdown menu
  </Step>
</Steps>

## Understanding Profile Specifications

### TAC (Total Area Coverage)

**Definition**: Maximum total ink percentage allowed

| Profile       | TAC Limit | Reason                |
| ------------- | --------- | --------------------- |
| ISO Coated v2 | 300%      | Standard for coated   |
| FOGRA39       | 300%      | Standard offset       |
| Japan Color   | 350%      | Japanese standard     |
| PSO Uncoated  | 260%      | Uncoated absorbs more |
| US Web Coated | 300%      | Standard for web      |

<Warning>
  **Exceeding TAC** can cause:

  * Wet prints (won't dry properly)
  * Smearing and offsetting
  * Paper saturation
  * Printer rejection
</Warning>

### Dot Gain

**Definition**: How much ink spreads when hitting paper

* **Coated paper**: Less dot gain (smoother surface)
* **Uncoated paper**: More dot gain (absorbs ink)
* **Newsprint**: High dot gain (very absorbent)

ICC profiles compensate for expected dot gain in their conversion rules.

## Embedding vs Not Embedding

### Embedded Profile (Recommended)

**What it means**: ICC profile data is included in the PDF

**Pros**:

* Ensures consistent color interpretation
* Printer knows exact color space
* Professional standard
* No ambiguity

**Cons**:

* Slightly larger file size (+50-100KB)

✅ **Always embed for professional printing**

### No Embedded Profile

**What it means**: PDF converted to CMYK but no profile info

**Pros**:

* Slightly smaller file

**Cons**:

* Printer may interpret colors differently
* Risk of color shifts
* Not recommended

## Profile Comparison

### Color Gamut Size

```
Largest to Smallest Color Gamut:

RGB (screen) ─────────┐ Widest
                      │
ISO Coated v2 ────────┤
FOGRA39 ──────────────┤ Similar
GRACoL ───────────────┤
                      │
SWOP ─────────────────┤ Slightly smaller
                      │
Japan Color ──────────┤ Higher TAC
                      │
Uncoated profiles ────┘ Narrowest
```

<Info>
  All CMYK profiles have narrower gamut than RGB - it's the nature of print vs screen.
</Info>

## Testing Your Profile Choice

### Before Full Production

<Steps>
  <Step title="Export Test File">
    Create small test with various colors
  </Step>

  <Step title="Review on Calibrated Monitor">
    Use monitor with color calibration if available
  </Step>

  <Step title="Order Physical Proof">
    \$10-50 investment to see actual printed colors
  </Step>

  <Step title="Compare">
    Compare proof to screen expectations
  </Step>

  <Step title="Adjust if Needed">
    * Try different profile
    * Adjust source colors
    * Use spot colors for critical hues
  </Step>
</Steps>

## Common Profile Mistakes

### Mistake #1: Wrong Region Profile

**Problem**: Using US profile for European printer (or vice versa)

**Result**: Color shifts, printer confusion

**Fix**: Always check with printer or match your region

***

### Mistake #2: Coated vs Uncoated Mismatch

**Problem**: Using coated profile for uncoated paper

**Result**: Colors too dark/muddy (ink absorption not accounted for)

**Fix**: Match profile to actual paper type

***

### Mistake #3: Not Embedding Profile

**Problem**: Converting to CMYK but not embedding profile

**Result**: Unpredictable color interpretation

**Fix**: Always embed ICC profile in PDF

***

### Mistake #4: Random Profile Selection

**Problem**: Picking profile without understanding or asking printer

**Result**: May not match printer's calibration

**Fix**: Ask printer first, or use ISO Coated v2 as safe default

## Advanced: Creating Custom Profiles

For advanced users or print shops:

### When to Create Custom Profile

* You have calibrated spectrophotometer
* Custom press setup
* Unique paper/ink combination
* Need exact color matching

### Tools Required

* Spectrophotometer (X-Rite, etc.)
* Color management software
* Test charts
* Knowledge of color science

<Note>
  Most users don't need custom profiles. Standard profiles work excellently for 99% of projects.
</Note>

## Profile Conversion Quality

### Factors Affecting Quality

| Factor               | Impact | Control                   |
| -------------------- | ------ | ------------------------- |
| **Profile accuracy** | High   | Choose reputable profile  |
| **Rendering intent** | Medium | Select appropriate intent |
| **Source colors**    | High   | Design CMYK-friendly      |
| **Black generation** | Medium | Trust profile settings    |
