Original color of sky - 51C 18M 13Y 0K. After placing (and checked by editing bitmap and taking point samples in PPaint and by rasterizing EPS in PShop) - 31C 13M 0Y 24K. This isn't UCR or anything - I can't get there with any settings - and the end result is radically different. There are no color management settings in CDraw active - and it seems to do the same thing on my CDraw 7 (win95) as it did with the clients CDraw 6 (problem was discovered when comparing the ripped EPS, the rasterized EPS, the CDR, the film, the proof with the original RGB Jpeg - everything matched [all looked kinda blah] except the jpeg). As you can imagine, this kind of strangeness isn't exactly working for the client [I think we've fixed the problem in the short term by recreating it with TIFFs and an exported .AI file in FHand] when the files they create end up looking grey and flat. /(_/(_/(_/(_/(_/(_/(_/(_/(_ Bernie A.

The jpeg when placed can then be edited in CDraw via Photopaint and at that point you can use the eyedropper tool to get values in various color models including cmyk - the cmyk value at this point is different from the one you get if you were to sample from the original jpeg or the original jpeg converted to cymk. The resulting output from the CDR can be interpreted at the rip which converts rgb to cmyk and gives the same value as PPaint does, which is also the same values that PShop gives if you rasterize an EPS generated from the above CDR. It's extremely frustrating for the client as it seems to happen on both their system and mine as mentioned in the previous post - and there is no clear cut reason as of yet as to why this is occuring, meaning that it could happen again. Wierdness like this isn't profitable. >,>, >,Anyone have any idea why a Jpeg when placed in CDraw would change color? >,>, >,6 (problem was discovered when comparing the ripped EPS, the rasterized >,>, >,EPS, the CDR, the film, the proof with the original RGB Jpeg - >,>, I think you've answer your own question.

Wierdness like this isn't profitable. The colour I normally use is CMYK but the colour I get in Coreldraw bears no relationship whatsover to the colour I get in the finished PDF. Source.
