 p.1 #6 · Inkpress/epson profile problem | |
Frank,
The reason I asked you to make a print with the profile anyway, even though it looked funky on screen, is that icc profile contain several sets of lookup tables - lookup tables that provide the actual conversion information for the different rendering intents, and lookup tables that render the converted image back to the screen. It's probably that second table that's screwy because, after you make the conversion, the whites that look cyan, are still reading 255,255,255, which we all know is white white white.
The same icc profiles have been supported in Ps since version 3 or 4 via the advanced color settings and since v5 when Adobe revamped the entire color management support in earnest. As long as the printer/ink/paper combination is still the same as when the profile was made, and nothing has changed with how the printer lays down the ink on that paper, then the profile should still work in whatever version of Ps you have. It's not connected to how old your printer or paper is, only if your printer is printing the same as it did when it was initially profiled.
I've actually never seen a profile do this exactly before, and it appears that only absolute whites are affected by the cyan preview. If the white drops down to near white, say 250,250,250 or so, the preview starts looking normal again. Colorvision, which made the profiling software that they used to make that profile, was never considered anywhere near the best software for making profiles, but was considerably less expensive than Monaco or Gretag, is almost certainly where the problem lies.
