Title: poor yellow in prints
Post by: marc.s on July 04, 2006, 11:45:52 pm

I get my prints made at a lab, and I'm having problems with deeply saturated yellows. They turn out less saturated and with a cool shift in the hue.. soft proofing doesn't really indicate that (only a small change)..

I think my monitor is properly profiled (but since I had to return my previous puck as it was all wrong and stuff I just don't know anymore..). Either way I know it's not this much off.

My question is whether problems with saturated yellows is a common problem with printers and any solutions..

Saturated yellows are the most noticeable area where prints can fall down. Take a look at [a href=\"http://www.lashier.com/home.cfm?dir_cat=26966]this gamut plot[/url] and you'll see why. If the images are being converted to sRGB for printing, the problem with be particularly noticible. Even if a printer profile is being used, if the profile wasn't made well the more saturated colors may suffer.

Chromogenic really seems to struggle with yellows. I base this on some profiling I did for a LightJet (Fuji Crystal Archive) and some profiles I just downloaded from a local lab using a Lambda (Kodak papers). A quick search finds somebody claiming that RA4 blows away inkjets in this respect but this hasn't been my experience.

The yellow in your plots looks pretty good ...

Yeah but this is with inkjet, UC's, and custom profile. Project the sRGB line thru and chop off what's outside.

They don't offer any profiles, so not sure how to go about that (or if it would help)..

Unfortunately I don't really have much choice in labs here at reasonable costs (I've only been able to find two I can use).
