Elie,
How does your plug-in allow me to limit (change) the total ink in
the file, whilst still using the same icc profile and conversion?
It can utilize a devicelink profile from the original (CMYK) based
on the original profile data, but with a lower inklimit.
EK: Thanks Thomas. As a matter of fact I replied from my PDA but did
not notice that it was a post on this forum and that my reply went
direct to Graeme.
So this is my reply, a little bit more detailed, in case it can be of
interest to others.
Alwan "DeviceLinkProfile" Photoshop plug-in allows you to apply
DeviceLinkProfiles (DVLP) to images in Photoshop.
If you get this plug-in, you still need one or more DVLP to apply.
Basically what you need is a DVLP which does not change your CMYK
working color space, say SWOP or ISOcoated etc..., but limits the
image output TAC to say 280% without affecting colors.
This DVLP should also preserve some print related characteristics
like pure primaries (C, M, Y, K) colors etc...
For more information about what a DVLP can do for you, you can read
Alwan LinkProfiler or CMYK Optimizer documentation which are quite
comprehensive and didactic.
It may be that your need does not justify the purchasing of a DVLP
builder, in this case you can try to find a consultant that can
provide you with the DVLP you need. If this is a problem, drop me a
mail and I will see how we can help you.
I really like the sound of it....saves my calculator, but do I
have to re-convert the RGB file to another profile with a lower TAC?
Nope you can convert CMYK > CMYK via a device link profile with the
PS plug-in.
EK: This can be an option, rebuilding your output CMYK profile with
280% TAC. To do that you need the output profile, say SWOP or ISO
coated etc... corresponding characterization data and a CMYK profile
builder.
Another option would be to continue working the way you do now and
once your CMYK image looks good for you, apply TAC reduction using a
DVLP as explained above before saving the image.
Kind regards,
