Hi guys,
I need to export an illustration from CorelDraw X3 to EPS format. I converted some objects to CMYK, and others to Grayscale. I did this using the find and replace option. Everything went fine according to the document info: my document contains only CMYK and Grayscale fills and outlines.
However, when I export the document to EPS, my EPS contains only CMYK objects. I checked this with Enfocus Pitstop. All grayscale objects have been converted to CMYK, and will consequently be printed using composite colors instead of pure black. This is not what I want.
How can I export an EPS in such a way that also the Grayscale objects remain true Grayscale?
Many thanks in advance!

When you export as EPS, the program prompts you a message, that allows to choose between RGB, CMYK or Grayscale. If you want to use mixed color modes, you must use Publish as PDF instead EPS, and choose Color Mode: Native under Advanced tab
May I inquire as to the thought process as to why you would have considered CMYK and then grayscale for print? I canunderstnfgCMYK and then a percentage of K only for gray or even an percentage of CMY. I am having trouble getting my mind around the use of grayscale.
The conversion of the grayscale to CMY or CMYKvaluse is most likely caused by leaving the apply ICC profile check box checked. Un check it and the grayscale items should convert to a build of K only.
Hi David,
Indeed maybe the problem is located in my thought process. I'll try to explain: I use a text processor (LaTeX) that can only deal with eps files. These eps files result from another program and are in the RGB colorspace.
For printing purposes, I need to deliver a pdf file. The printer company requires that I convert those figures that need to be printed in color to CMYK. Everything else (figures, body text) should be grayscale. However, some of these color figures contain black text and black and gray lines as well. I want these to be printed as true black instead of composite black. The printer company recommended to convert the black text and lines to grayscale, and all other objects to CMYK.
I use CorelDraw to import the eps files, convert all RBG color objects to CMYK and all RBG black objects (text and lines) to Grayscale. When I export the resulting figure as an eps file, all Grayscale objects have been converted to CMYK again.
To circumvent the problem, right now I have asked the printer company if it's ok to convert the color figures to CMYK, and use only the K channel for the black and gray objects (text/lines) while keeping the CMY at 0.
Maybe this explains the situation. I am very interested in your opinion about this matter.
Kind regards,

I started printing in 1974 so I'm sure that the advice you got was either miscommunicated or just plain incorrect, printing isn't what it used to be and I'm not sure it ever was was it used to be. :-)
The first thing to remember is that all postscript compliant applications will see either vector or raster (bitmap) objects, Corel handles color conversion differently for those items. All grayscale bitmap images will be converted to the K channel of the CMYK color model only.
All vector objects that are filled or outlined with a grayscale color model will when exported to an EPS are exporting to K of the CMYK color model for me. The best thing in my opinion is to not use the grayscale color model, use selected percentages of K in the first place.
This will solve this issue but to understand how Corel handes color got to www.graphictechnology.com and get my book. It is a long hard boring read but it covers what you need to know about using Corel color management. To solve all your color issue onth eforum is just too much to post, it is a 30 meg PDF download at 90 pages if I could have said it in 80pages Iwould have. :-)
