The general consensus, from everything that I’ve read at least, says to use AbsCol intent when matching a press or proofer on an inkjet printer, which makes sense.
yes, although as you are finding, it doesn’t always work first time around…
This way the inkjet will show you the exact colors (as best it can) of the press/proofer. Which of course includes showing you a yellowish (or other color) paper white in some cases.
If you do not want the yellow tint to appear on the inkjet prints, but you still want to use AbsCol intent, you can edit the white point of the destination profile to match the wp of the source profile.
yes you could but I would not recommend it. All colors are relative to white. So if you change the white without changing the image / palette colors then the colors will look different relative to white… not typically good
So my question is, are there any downsides to editing the wp like this? If you lay the proofer output next to the inkjet output, shouldn’t all of the colors match (as well as ICC worflow allows) except for the paper white?
no, they shouldn’t. If you don’t want to simulate paper white then do relative colorimetric proofs and leave it at that. If you can find a proofing paper that is the same color as the simulated color then you can do a very effective relative colorimetric proof - in fact I prefer this method.
Is it best to leave the wp alone so you eye isn’t referencing two distinct white points when viewing the output?
two whites is OK but the colors need to be formulated relative to each white (and you shouldn’t view them side by side). If you choose to do absolute colorimetric proofing then you can tweak the white of the reference profile OR the proofer profile. Just remember that if you tweak a reference profile for a particular use then it should never be used for other purposes, like soft proofing. It’s a good idea to name such profiles to avoid future confusion. - like “SWOP TR001for xxx proofer”. Also, like we always say…trim all abs col proofs before viewing
Thanks for any clearification.
no problem… a very good question.
