I want to convert an EPS file (with Pantone colours-CMYK) to a JPEG(RGB) which will be viewed on a browser. When I do that, the Pantone colour in the EPS file is drastically different to the RGB version. What is the best way to simulate the Pantone colour when I rasterise the EPs in Photoshop ? This has been a bit of a pain for a while....is there anyway I can make Photoshop better understand Pantone colours....Ive tried with different profiles but that hasnt been much of a help..
..any advice would b great !

thanks
Iris

I need a little more information,

What's the original souce of the EPS file, Illustrator, Coral Draw, Freehand. Etc....

Are the values in the EPS defined as Pantone Colors, or Pantone Colors Defined/Simulated using CYMK inks?

Pantone colors defined in one program will not necessarly transate to another application. Pantone is realy designed as a spot color system the values on screen mean vary little as they are intened to be reproduced using specific pantone inks and Pantone colors Simulated using CYMK values can vary widely.

Well the source of the EPS file is Illustrator and the values in the EPS defined as Pantone colours. I understand that
Pantone colours would behave differently in different applications...so Im looking to convert the Pantone EPS into the closest possible RGB jpeg...

thanks

The most current version of Photoshop and Illustrator should match, but there have been past issues with a bad Pantone library in Adobe Illustrator, so the colors you are seeing in Adobe Photoshop could be the right ones. Have you compaired them to a Pantone book?

If you are using Windows Version 10, be sure to patch to 10.0.3 of Adobe Illustrator and redefine your pantones colors with the latest Library.

It safest for color matching is to make the conversion is in illustrator, either convert all the colors to RGB in illustrator or export the image in a bitmap format such tiff or PNG.
