Opening old .eps files from PS4.0

Question

Hello Community,I have received some old visual material that I unfortunately cannot open. The image is split into 5 files (.eps, .c, .y, .m, .k).Does anyone have any advice on how I can put the files back together and open them?Thanks in advance!

If I follow these steps, the result is as follows...

EDIT: You may need to create a Custom CMYK profile to match a European condition, as the old Legacy Default CMYK is probably based on SWOP. Do the CMYK colour values look correct, despite the preview? This will also help you to determine if this is simply a preview issue or an issue with the actual data.

Try assigning the Photoshop 4 or 5 Default CMYK profile, is the preview any better?

The separations were either created in an old version of Photoshop before modern ICC colour management, or perhaps they were separated by 3rd party prepress software back in the day perhaps for a different CMYK condition. Could this separation be for newsprint?

If you have access to page layout software, you could place the preview .eps image and see what you get, but this will still be subject to colour management.

I'm happy to take a look at the 5 files offlist, you can send me a private message with a download link and I'll report back.

@Shorty0811 – Glad you have sorted this out now!

To update this topic for the public forum from the offlist exchange...

The highlights and neutrals look as expected in CMYK and Lab values. The skintone has some K in it, however it isn't shadowed, so this must be using a higher GCR separation. The shadow values are well under half of what they should be in K, so this may have been an artistic treatment or a "ghosting" for a text panel (however it is very dark for a ghosted panel, which ideally wouldn't have any K in it anyway, and the image is too light for a standard separation).

Colour management has changed since PS4, I am guessing that these have a 30-40% dot gain and using the old Eurostandard Uncoated or Eurostandard Newsprint colour settings.

That being said, even the colour numbers are off, they are all very light, don't be fooled by the assigned profile, if the darkest shadow is using ~3K% K, then something is very non-standard about these separations.

I would suggest that you assign the best CMYK profile that you can, then convert to RGB. Colour correct in RGB by setting a good shadow/highlight/midtone-neutral at the very least, then convert to a modern CMYK if required.
