2024 Illustrator Update save as eps changing sublimation colours

[Matilida26920480qmbh]

Recently updated to Illustrator 2024 and when I print new sublimation files saved as eps the printed colours differ from files used before the new update when all the files are the same, only difference is the time of when the file was saved. The only method I have found to work is by reinstalling an older version of Illustrator.

Has anyone else had the issue with sublimation printing?

Please describe step by step.

You save an EPS and then print it?

You save the EPS by printing a file?

What does it mean: the colors change? The values change? The output changes? Is that an RGB or CMYK file? WHich options do you set up when saving?

[Matilida26920480qmbh]

Yes I save as EPS then print it. Which we have done the same for the last 5 years.

The change of colours is actually on the fabric once they have been printed - all of the values on the files are the same. 

It doesn't seem to be on all colours but Purples are very different.

Is it an RGB file?

What happens if you turn off the optio to "Include CMYK PostScript in RGB Files" when saving as EPS?

[Matilida26920480qmbh]

Hi Ton, yes it is an RGB file. And yes I have tried to Include CMYK PostScript in RGB Files and this gives a totally different colour once printed.

I  asked to turn it off.  Do you need to use EPS to print it?  PostScript does not support ICC color management.

Hi Ton,

Yes sorry I have tried both leaving it on and off and leaving it off gives a totally different colour. It is closer when it is ticked. I have always had it ticked. 

I have tried to save as a PDF but this gives a totally different colour again.

How are your Clor Settings setup? There goes something wrong with color management. Do you have an color profile for your printer?
