Author Topic: Preview Image Colors WAY Off (Read 7624 times)

Anyone else having trouble with the preview images for their most recently accepted images? I'm a vector contributor at CanStock and the most recent batch of my images have preview colors that look fluorescent. This never happened with my older images there.

Also, review/approval time there is really slow lately. It's taking over a month for images to be reviewed.

YES! I've thought it might just be me and couldn't understand what's going on. I made a "test" with uploading ~10 vectors, to figure out the process, etc., and the preview images are horrible. I checked the color mode, it's RGB, like requested and there's no such problem anywhere else, so I don't know, it should be something on their end. I'm secretely hoping, that after they get reviewed (been also waiting for a month now) it will change, if not, there's no sense uploading more, because they get messed up. $:-\$

I contacted them and told them about it. They asked me to provide 2 or 3 image ID numbers of the affected files, so I did that. Still waiting to hear back from them.

Did you hear from them?

I contacted them too, they replied kinda fast, but in the meantime I might have figured it out on my own, what the problem is. When saving the EPS8 file in Illustrator, there's an option that says: Include CMYK PostScript In RGB Files, wich was checked. Because there was no such problem with this until now, I did not bother looking into it, but as a test I have saved 3 vector files now with this option unchecked, uploaded them and they look all right now! This might have been the problem, hopefully it's all clear now and won't happen again.

The fault lies with Canstock. I'm experiencing the same problem.

Yes, it's their fault, that somehow their system probably chooses this CMYK PostScript and/or tiwsts it, instead the RGB colors. With no other agency happens something like this. However, could you try what I have suggested? Save just one EPS8 with "Include CMYK PostScript In RGB Files" unchecked und upload it. If, by any chance, it works for you too, then we really migh have figured this out.

Here's the article about this PostScript that made me think: https://jamietshaw.wordpress.com/2011/01/23/preventing-rgb-colour-shifts/

Well, the thing is, I always upload CMYK EPS8 files (plus an RGB JPEG) so I suppose this CMYK Postscript option is irrelevant for me (but it's unchecked by default). And the previews are still off on Canstock, but they're okay at every other agency. I remember Thinkstock had the same problem when my files were transferred from iStock to Thinkstock. Their previews were always off in terms of color (too bright and saturated).

Well, I got the runaround in my first support ticket and was then being ignored so I started another one which was also ignored. So I guess CanStock has decided this isn't their problem.

However, the suggestion to uncheck the "Include CMYK PostScript in RGB Files" box when saving the Illustrator eps file DOES work after all. I unchecked that box, saved a test file and uploaded it and the preview colors were just fine.

So now I just have to delete the 25 or so incorrect looking files and re-upload them.

Whatever changed at CanStock happened to me around May 12th. Up until that point, I'd saved over 200 vector eps files with no problem and with that box checked.
