why do i problems with an EPS export & colour shift?
Hi
Quite new to all this and probably doing something stupid 😀 but having problems with the colour output from the Corel Draw EPS export.
When I create something in Corel and use EPS the colours coming into Colorip for the Versacamm or into Photoshop are Flat. Also some of the colours are shifting, especially blue to purple (although I know blue is always a problem as far as CMYK and printing goes).
I’m using Corel Draw 11 and have colour management turned off and the ‘apply ICC profile’ in the export dialog unchecked.
I have found a workround by exporting as an ai into Illustrator and then exporting from Illustrator as an EPS. Doing this I get the correct colours showing in the Colorip. Also if I import a bitmap into Corel and export it as an EPS that’s fine. So it seems to be the way Corel exports CMYK with EPS, is it very conservative in it’s gamut when using CMYK?
Like I said, I’m new to all this (though I’ve been using Corel for some time) so I may be missing something obvious in Corel or general colour management.
Any help would be greatly appreciated otherwise I might have to learn how to use Illustrator 🙁
Thanks
Danny.

hi
in colour management turn the monitor to rgb forist green will look on the screen like whot it prints ugh!chris

Hi Chris
Thanks, tried that, doesn’t make any difference on my machine. Like I said the stupid thing is, if I export to Illustrator first then to EPS, what I see on screen is roughly what I get.
Maybe my installation of Corel is Screwed!
Cheers

if your using a cadett i use troop as the rip and if you go in to view you can soft proof which gives the exact colour your printing

If its a bitmap you bringing into Corel , convert it to a bit map WITHIN corel before you export
-
Not exporting as CYMK are you ??

Hi Rodney,
It’s fine with bitmaps as I always bring them in as RGB and have the export set to RGB in the EPS export dialog.
I think Forbie is right, anything created in Corel and exported as EPS seems to default to CMYK.
I can drag what I’ve created in Corel onto an open RGB document in Illustrator and the colours when saved as an EPS from Illustrator are fine.
Can anyone else replicate this or is this just how things are.
Cheers,
Danny.

Either export from Corel in the native format the bitmap is in or convert the bitmap to what you are exporting out as.
IE if you have only RGB , then export to RGB (option in dialog box) or if you want to export to CMYK and you have RGB , then convert the RGB image to a CMYK bitmap.Your biggest problem is with mixed graphics , IE RGB and CMYK. In Corel , it’s best to convert all bitmaps to the same “format” and export as that “format”
A lot depends on your RIP , cos thats the thing that translates RGB to CMYK and thats what tells the printer how to deal with out of gamut colour etc.
Color workflow is one of the bugbears in digital printing. there is no one solution either.
Essentially NO printer is a RGB device (additive – you add colours to get white , luminance etc is also a problem) albeit it might accept RGB input , it “swaps” those colours to CMYK and is a subtractive system.
In reality you need to calibrate your monitor and the RIP to “see” what your printer will output. Thats Why I like the Wasatch , it shows in real time what the effects of the various RIPS controls re colour do.The RIP does the transform based on the ICC profile and thus What we see in the RIP display is what we get. so If I change the way the that a CMYK bitmap is treated , like going from absolute colormetric to perceptual , I actually see exactly whats gonna get printed. -
HI
if i send any vector fade fills in rgb they dont print as nice as sent cmyk from coral but if a image is rgb then send it as that seams to keep the colours better problem comes when you have a rgb bit map & fade fills.
it may be me but i think that cmyk images print a bit flat comparedchris

Rodney is right. Couldn’t have said it better myself

Hello,
When you export as EPS or print to a PostScript driver from Corel, by default all RGB vectors on your screen are converted into CMYK colour space.
They do this based on the color management settings in Corel.When you export as ai, RGB colors stay as RGB which is why you dont see the problem going to illustrator.
I would say the problem is in the color managment settings in Corel, try setting the original defaults as these generally work OK.
Best regards
