LINK(1)

🌸 NAME 🌸

Link — as in, link ICC profiles. That's the name, bestie, short and iconic. This whole page is LINK(1), it lives in the User Commands part of the manual, and it's about collink. 💅

💖 DESCRIPTION 💖

Link ICC profiles.

No cap, that is the entire description. Short. Punchy. Ate. ✨

🎀 SYNOPSIS 🎀

okay so here's the whole vibe of it:

collink [options] srcprofile dstprofile linkedprofile

You hand it a source profile, a destination profile, and where you want the linked one to go. Then you sprinkle options on top like glitter. 🌈 And here are all of them, no skipping, I would never 🫶

• -v — Verbose. It tells you what it's doing. 🗣️
• -A manufacturer — Manufacturer description string.
• -M model — Model description string.
• -D description — Profile Description string. The default is "inoutfile".
• -C copyright — Copyright string.
• -V — Verify an existing profile, rather than link. It's giving "vibe check the profile before you commit". 🔍
• -q lmhu — Quality: Low, Medium (def, the default), High, Ultra.
• -r res — Override the clut res. that -q set.
• -n — Don't preserve device linearization curves in the result.
• -f — Special :- Force neutral colors to be K only output.
• -fk — Special :- Force K only neutral colors to be K only output.
• -F — Special :- Force all colors to be K only output.
• -fcmy — Special :- Force 100% C, M or Y only to stay pure.
• -p absprof — Include an abstract profile in the link.
• -a file.cal — Apply calibration curves to the link output and append linear.
• -H file.cal — Append calibration curves to the 3dlut.
• -s — Simple Mode. This is the default, bestie, so if you do nothing you're already in it. ✨
• -g [src.gam] — Gamut Mapping Mode [optional source image gamut].
• -G [src.gam] — Gamut Mapping Mode using inverse outprofile A2B.

🍬 Simple Mode Options 🍬

• -i in_intent — the Simple Mode intent. Pick one: p = perceptual, r = relative colorimetric, s = saturation, a = absolute colorimetric.
• -o out_intent — p = perceptual, r = relative colorimetric, s = saturation, a = absolute colorimetric.

🌀 Gamut Mapping Mode Options 🌀

• -i intent — set the linking intent from the following choice:
  • a — Absolute Colorimetric (in Jab) [ICC Absolute Colorimetric]
  • aw — Absolute Colorimetric (in Jab) with scaling to fit white point
  • aa — Absolute Appearance
  • r — White Point Matched Appearance [ICC Relative Colorimetric]
  • la — Luminance axis matched Appearance
  • p — Perceptual (Preferred) (Default) [ICC Perceptual]
  • pa — Perceptual Apperance
  • ms — Saturation
  • s — Enhanced Saturation [ICC Saturation]
  • al — Absolute Colorimetric (Lab)
  • rl — White Point Matched Colorimetric (Lab)

bestie the original spells it Apperance and we are keeping it exactly like that. no editing, that's the rule. 💅

• -w [J,a,b] — Use forced whitepoint hack [optional target point].
• -c viewcond — set the source viewing conditions for CIECAM02, either an enumerated choice, or a parameter.
• -d viewcond — set the destination viewing conditions for CIECAM02, either an enumerated choice, or parameter:value changes. The choices and parameters are:
  • pp — Practical Reflection Print (ISO-3664 P2)
  • pe — Print evaluation environment (CIE 116-1995)
  • pc — Critical print evaluation environment (ISO-3664 P1)
  • mt — Monitor in typical work environment
  • mb — Bright monitor in bright work environment
  • md — Monitor in darkened work environment
  • jm — Projector in dim environment
  • jd — Projector in dark environment
  • tv — Television/Film Studio
  • pcd — Photo CD - original scene outdoors
  • ob — Original scene - Bright Outdoors
  • cx — Cut Sheet Transparencies on a viewing box
  • s:surround — n = auto, a = average, m = dim, d = dark, c = transparency (default average)
  • w:X:Y:Z — Adapted white point as XYZ (default media white)
  • w:x:y — Adapted white point as x, y
  • a:adaptation — Adaptation luminance in cd.m^2 (default 50.0)
  • b:background — Background % of image luminance (default 20)
  • l:imagewhite — Image white in cd.m^2 if surround = auto (default 250)
  • f:flare — Flare light % of image luminance (default 0)
  • g:glare — Flare light % of ambient (default 1)
  • g:X:Y:Z — Flare color as XYZ (default media white, Abs: D50)
  • g:x:y — Flare color as x, y
• -t tlimit — set source total ink limit, 0 - 400% (estimate by default).
• -T klimit — set source black ink limit, 0 - 100% (estimate by default).

🖤 Inverse outprofile A2B Options 🖤

• -k tezhxr — CMYK Black generation:
  • t = transfer K from source to destination
  • e = retain K of destination B2A table
  • z = zero K
  • h = 0.5 K
  • x = maximum K
  • r = ramp K (default)
• -k p stle stpo enpo enle shape — p = black target generation curve parameters.
• -k q stle0 stpo0 enpo0 enle0 shape0 stle2 stpo2 enpo2 enle2 shape2 — q = transfer source K to dual curve limits.
• -K parameters — Same as -k, but the target is K locus rather than K value itself.
• -l tlimit — set destination total ink limit, 0 - 400% (estimate by default).
• -L klimit — set destination black ink limit, 0 - 100% (estimate by default).
• -3 flag — Create "3DLut" output file as well as devlink:
  • e — eeColor .txt file
  • m — MadVR .3dlut file
• -I b — Apply BT.1886-like mapping with effective gamma 2.2 to input.
• -I b:g.g — Apply BT.1886-like mapping with effective gamma g.g to input.
• -I B — Apply BT.1886 mapping with technical gamma 2.4 to input.
• -I B:g.g — Apply BT.1886 mapping with technical gamma g.g to input.
• -e flag — Video encode input as: (the flags are the ones listed under -E right below 👇)
• -E flag — Video encode output as:
  • n — normal 0..1 full range RGB levels (default)
  • t — (16-235)/255 "TV" RGB levels
  • 6 — Rec601 YCbCr SD (16-235,240)/255 "TV" levels

  • 2 — Rec2020 YCbCr UHD (16-235,240)/255 "TV" levels
  • C — Rec2020 Constant Luminance YCbCr UHD (16-235,240)/255 "TV" levels
  • x — xvYCC Rec601 YCbCr Rec709 Prims. SD (16-235,240)/255 "TV" levels
  • X — xvYCC Rec709 YCbCr Rec709 Prims. HD (16-235,240)/255 "TV" levels
• -P — Create gamut gammap.wrl diagostic.

yes, diagostic. that's the original spelling. keeping it. no notes. 💅

and that's the whole page, bestie!! 🫶 this one comes from the collink source, dated September 2014, and it's page LINK(1). go forth and link your profiles. mwah. 💖✨🎀
