InkRIP — colour & ICC concepts (learning depth)

InkRIP-only. Software learning only. Default stance until Eric says otherwise: stay on factory / bundled profiles — do not run full ink-limit → linearisation → custom ICC on Monitor-PC yet.

Why colour looks “wrong” after print

Monitors use light (RGB, additive). Printers use ink (CMYK + optional White / Varnish / spot, subtractive). Vibrant on-screen colours often print duller unless colour-managed. InkRIP’s job includes translating design colour into ink for the selected driver / media.

Training: RGB vs CMYK.

Practical habits (AM design-practices framing)

What an ICC profile is

ICC = International Color Consortium. Think of a profile as a translation dictionary between devices so colour stays consistent from capture → screen → printer.

Pipeline (AM Color Manager Part 1):

  1. Input — camera/scanner attaches an input profile.
  2. PCS (Profile Connection Space, often CIE Lab / XYZ) — device-independent hub.
  3. Output — printer output profile maps PCS → ink amounts for that printer + ink + media.

Four profile types (training)

Type Role
Input How scanners/cameras see colour.
Display How monitors show colour (monitor calibration).
Output Printer capabilities — usually ink + media specific. Main focus for InkRIP Color Manager.
Working space Idealised edit spaces (e.g. sRGB, Adobe RGB) — not tied to one device.

Why care: brand colour consistency; soft-proof before wasting ink; gamut mapping when a colour is out of printer range.

Generic (factory) vs custom profiles

Factory / generic Custom
Source Ships with product / InkRIP Colour Profiles packages on cncu Built with spectro + charts for this machine + ink + media
Good for Learning, first jobs, many shops Critical brand colour / problem media
Assumes Every unit is identical (often not true) Measured reality of this setup

Learning rule for Vector now: use factory / default profiles attached to the InkRIP printer driver / Colour Profiles leftovers. Full custom ICC series (ink limit, linearisation, spectro) waits until Eric names printer + media + whether a spectrophotometer is available.

Manual deepeners (boxed): Create-ICC-Profile-by-InkRIP-Basic-Steps.pdf under T:\V\sources\manuals\inkrip\ / cncu; Color Manager Parts 2–11 on softwaretraining (spectrophotometer, ink limit, linearisation, import/export, use new profile).

Where ICC shows up in the UI

Software-only drills

  1. Watch / read RGB vs CMYK + About ICC (Parts above) — no printer needed.
  2. In InkRIP, locate Color Manager entry points on 7.2.14.0.4; list which factory profiles appear — do not create a new profile yet.
  3. In Job Manager (empty or sample jobs), note the Mode column concept.
  4. Pause before ink-limit / linearisation / spectro steps until Eric opens ICC depth.
