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" }

{
  "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"
}

{ "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)",

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

{
  "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." },

  ],
  "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.
