Who is this for?

Role Use case
Print designers Check Pantone-to-CMYK conversions without leaving your editor
Prepress engineers Estimate ink costs, verify color accuracy (Delta E), analyze ICC profiles, run preflight checks
Packaging teams Convert paper weights, separate spot vs process colors, cost entire print runs, simulate substrate shifts
Brand managers Find the closest Pantone match to any HEX color

Install

pip install mcp-print

Requires Python 3.10+. Zero external dependencies beyond the MCP SDK.

Configure with Claude Code

Add to your Claude Code MCP config (~/.claude/settings.json or project .mcp.json):

{
  "mcpServers": {
    "print": {
      "command": "python",
      "args": ["-m", "mcp_print"]
    }
  }
}

Restart Claude Code — all twelve tools will be available immediately.

Usage Examples

Once configured, just ask Claude naturally:


Pantone Lookup

"What's the CMYK breakdown for Pantone 485 C?"

Fuzzy matching accepts any format: "485C", "pantone 485", "485 coated", "Warm Red"

{ "name": "Pantone 485 C", "c": 0, "m": 95, "y": 100, "k": 0, "hex": "#FF0D0D" }

Pantone CMYK lookup example


Reverse Pantone Search

"What Pantone colors are closest to #DA291C?"

{
  "matches": [
    { "name": "Pantone 485 C", "c": 0, "m": 95, "y": 100, "k": 0, "hex": "#FF0D0D" },
    { "name": "Pantone 485 M", "c": 1, "m": 93, "y": 99, "k": 2, "hex": "#FA0E03" }
  ],
  "search_type": "hex #DA291C"
}

Color Conversion

"Convert CMYK 100/44/0/0 to RGB"

{ "r": 0, "g": 143, "b": 255, "hex": "#008FFF" }

Ink Estimation

"How much ink for 10,000 A4 flyers at 35% coverage on offset?"

{ "ink_grams": 327.44, "ink_kg": 0.3274, "cost_estimate_usd": 8.19 }

Full Print Job Costing

"Cost estimate: 5,000 A4 flyers, 4-color offset, 120gsm, double-sided"

{
  "total_cost_usd": 628.14,
  "cost_per_unit_usd": 0.1256,
  "breakdown": {
    "ink": 11.34,
    "plates": 280.00,
    "makeready": 200.00,
    "run_cost": 136.80
  }
}

Color Matching QC

"Compare brand blue (100/72/0/18) vs proof (98/70/2/20) — is the Delta E acceptable?"

{ "delta_e": 3.41, "interpretation": "fair — noticeable difference" }
Delta E Quality
< 1 Excellent — imperceptible
1 - 3 Good — barely perceptible
3 - 6 Fair — noticeable
> 6 Poor — obvious difference

Spot vs Process Recommendation

"Should these colors be spot or process?"

{
  "spot_colors": [
    { "nearest_pantone": "Pantone 485 C", "delta_e": 0.0, "reason": "Close match — use spot for accuracy" }
  ],
  "process_colors": [
    { "nearest_pantone": "Pantone 375 C", "delta_e": 8.2, "reason": "No close match — reproduce as CMYK" }
  ]
}

ICC Profile Inspection

"What color space does this ICC profile use?"

{
  "profile_name": "ISOcoated_v2",
  "color_space": "CMYK",
  "device_class": "Output (Printer)",
  "version": "2.4.0",
  "pcs": "XYZ"
}

Barcode Ink Coverage

"Ink coverage for an EAN-13 barcode at 37mm x 26mm?"

{
  "coverage_percent": 52.0,
  "recommended_ink": "Process Black (K: 100)",
  "print_method_suggestion": "offset — good resolution for medium modules"
}

Barcode ink coverage analysis example


Paper Weight Conversion

"What's 80 lb text in GSM?"

{ "value": 118.42, "from_unit": "lb_text", "to_unit": "gsm" }

Preflight Check

"Validate my file for offset printing: CMYK, 300 DPI, 3mm bleed, fonts embedded"

{
  "status": "pass",
  "checks": [
    { "name": "color_mode", "status": "pass", "message": "CMYK is correct for offset." },
    { "name": "resolution", "status": "pass", "message": "300 DPI meets the minimum of 300 DPI for offset." },
    { "name": "bleed", "status": "pass", "message": "3.0 mm bleed meets the 3.0 mm minimum for offset." },
    { "name": "fonts", "status": "pass", "message": "All fonts are embedded." },
    { "name": "ink_coverage", "status": "pass", "message": "Total ink coverage 280% is within safe limits." },
    { "name": "transparency", "status": "pass", "message": "No transparency detected." }
  ],
  "summary": "6 passed, 0 warnings, 0 failed out of 6 checks.",
  "recommendation": "File is ready for production."
}

Checks color mode, resolution, bleed, font embedding, total ink coverage, and transparency against the target print method (offset, digital, flexo, gravure, screen).

Check Fail Warning
Color mode RGB/spot for offset/flexo/gravure/screen RGB for digital
Resolution Below 75% of method minimum Below method minimum
Bleed No bleed Below method minimum
Fonts Not embedded
Ink coverage > 340% > 300%
Transparency Present (needs flattening)

Substrate Simulation

"How will CMYK 50/30/20/10 look on newsprint vs glossy coated?"

{
  "original": { "c": 50, "m": 30, "y": 20, "k": 10, "hex": "#73A1B8" },
  "simulated": { "c": 57.5, "m": 38.3, "y": 29.8, "k": 31.9, "hex": "#4A6B7A" },
  "substrate": "newsprint",
  "print_method": "offset",
  "adjustments": { "dot_gain_applied": 30, "absorption_k_added": 16.2 },
  "delta_e_from_original": 21.11,
  "warning": "Severe color shift — this substrate may not be suitable for color-critical work."
}

Six substrate profiles with different dot gain, absorption, and paper tint characteristics:

Substrate Dot gain (offset) Tint Typical use
glossy_coated 12% None Magazines, brochures
matte_coated 18% Slight warm Art books, reports
uncoated 22% Warm Letterheads, books
newsprint 30% Yellow/gray Newspapers, flyers
kraft 25% Strong brown Packaging, bags
recycled 25% Slight gray Eco-friendly prints

Pantone Database

The built-in database contains 2,415 Pantone colors:

Series Range Description
Numeric 100–699 Yellows, oranges, reds, pinks, purples, blues, greens, grays, browns
7000 series 7400–7547 Extended gamut colors
Named Black, White, Warm Red, Reflex Blue, Process Blue, Cool/Warm Grays 1–11, Hexachrome series

Every color is available in three finishes: Coated (C), Uncoated (U), and Matte (M).

Fuzzy matching handles format variations — "485C", "pantone 485", "485 coated" all resolve correctly.
