From CorelDraw to PDF: colour changes??

[Astrid_Stürner@adobeforums.com]

Recently I designed a brochure in CorelDraw 11 and used Acrobat 6 Standard(Windows XP) to turn the artwork into a pre-press PDF.

In the artwork, I had used the colour Pantone 7473 C (a dark green) a lot. Strangely enough, in the PDF some graphics done in this colour appeared in another shade of green. I checked the CorelDraw file several times, but every single graphic is done in Pantone 7473 C - no error there.

So now my question is: How come that one and the same colour is displayed in different shades in this PDF done with Acrobat 6?

create an eps from the corel file and distill this manually in the dsitiller application using press settings. How do the colours look?

Hello, de Siem,

thanks a lot for your interest in my little Acrobat problem!

I've tried your proposal, but unfortunately there is no difference to the PDF generated directly from CorelDraw. In the EPS, though, the colours look perfect - no different shades of green. So it seems Acrobat Distiller really is the problem after all...

[de_Siem@adobeforums.com]

Distiller does not change colours, apart from when using smallest file size or standard job options (and then it changes the colourspace)
Using press job options will not change anything in the eps file colourwise. It's really a garbage in garbage out conversion tool.

Also keep in mind that when you ciew the eps, you're most likely only seeing a bitmapped preview of the actual file.

Are you using any colour management in Colour draw at all?
Does the same happen if you create a new corel file and convert that to pdf?
Before converting to pdf try this:
Go to start>settings>pritners
right-click on the adobe pdf printer,
under the pdf settings tab change the conversion settigns from standard to press.
Click ok.

Using this setting print to the adobe pdf printer from corel. (Also make sure there's no 'colour' option checked in corels print dialog box.)

I wonder if your problem was similar to mine? In Acrobat 6 see if you have a tick against Advanced / Proof Colors. If it is ticked, then untick it. I found my colors changed immediately.

Karen, Thank you! Thank you! I've been grousing to myself about the pre-press coloring since I upgraded. Again, thank you.

Great! Bob, I took 2 whole days of trying to work that one out. I upgraded on Sat morning and didn't work out solution till Monday lunchtime and I was driving myself crazy. I think Acrobat defaulted to the Advanced/Proof Colors when installed and I had no idea what to look for even though I was familiar with previous versions.

I'm glad for both of us it worked out.

Hello, de Siem and Karen,

thanks a lot for your tips! I've tried de Siem's trick and created a new Corel file - bingo! Seems Corel has gone bonkers again...

Karen, could you please give me a hint where to find Advanced/Proof Colours in Acrobat 6? I'm not much of a Acrobat pro to begin with, and working with the German version my search wasn't crowned with success...

[Karen_C@adobeforums.com]

In Acrobat 6 Professional version it's just
Advanced/Proof Colors (turn the tick OFF)
