Question

Hi,

 

One of our clients has changed the printer settings from the old color settings to the new color settings.

 

Old color settings currently we followed: "Coated FOGRA39 (ISO 12647-2-2004)"

New color settings to be followed: "PSO Uncoated v3 (FOGRA52)"

 

For new projects, we need to follow the "PSO Uncoated v3 FOGRA52" settings in the overall book.

 

For example, If the graphic artist processes the images in old color settings using Illustrator/Photoshop and produces the .EPS file. How could be validate the .EPS file whether the correct color settigs are used or not.

 

Is it possible to validate the EPS?

 

Thanks,

Santhosh

What kind of print work is being done? FOGRA39 is a sort of generic standard for offset printing on either matte or glossy paper. However, many kinds of print media have their own specific material profiles.

 

I'm used to seeing "coated" or "uncoated" standards being applied to spot colors used in logos/branding. Pantone is the most commonly used color library. But anyone specifying such colors should have a set of Pantone Formula Guide physical swatch books to be able to see the actual colors and be able to compare those to printed results. Unfortunately those swatch books are not cheap to buy.

 

As Ton said, the EPS format has serious limitations. Using PDF would be much better, especially if the print shop has a print setup that natively supports PDF.

There will be quite a difference between coated and uncoated regarding the total ink amount allowed.

The amount in the coated files will be too much for uncoated.

But .eps files? EPS files do not support ICC color management, so the values in the file will be the values used to print.

Converting CMYK TO another CMYK can mess up your blacks.

Talk to your printer, he may be able to do the conversion when nessecary.

Talk to the printer.
