Title: How to use Device Link Profile correct?
Post by: aaronchan on July 22, 2013, 10:15:56 am

Or should I say when do we use DL profile?

I use RGB printer driver most of the time for my fine art clients.
But when it comes to commercial job, sometimes I don't get the color as my client wants,
such as Chinese RED which is 100% M and Y.

As I remember, when CMYK file goes to the printer, it will go through the conversion process which will go through the L*ab space then back into the CMYK printer profile. I think that's the time the color has been converted. So if I use the DL profile, would it bypass that and help me to preserve 100% M and Y for the final output?

p.s. I have Wasatch RIP and i1Profiler which now can make DL profile.

Thanks
Aaron

You could try using the source RGB to CMYK for a DLP but don't expect miracles. You have the tools, might as well try it. Ideally base the source on the RGB working space you are using.
