    Hello,

    I read the article on exporting PDFs and converting them to CMYK on export. Sounds great and very time saving but I, unfortunately, work with people who will not wake up and smell the coffee. I’m just wondering if there is anyone who HAS done this and how their files turned out once you got the final printed versions back. I’m working with a company who makes large catalogs and their image colors are ALLLLL over the place and it would save some EXTREME time if I could convince them to convert to CMYK on export instead of manually changing all the images… or if I could take the issues into my own hands and do that with confidence that it will turn out correctly.

    Thanks!

    I have never been able to get exports to convert to CMYK. I find when we export, they all go to RGB. WE use the print option. We print to a PostScript file and distill them.

    The converting has worked for me, I check the images in Acrobat after and it exports correctly. I just haven’t sent a file to the printer changing the images that way. It would be nice to see the two side by side to compare colors and see if there is a difference.

    If the images are photographs where color is crucial, converting to CMYK first is best. (Use batch scripts in Photoshop)

    Otherwise, find out from your printer what they prefer. Many RIPs are now set up so that RGB is the preferred format; the RIP will convert to CMYK.

    The main reason I’m hoping that this will work is because there is a large number of images (208-page catalog with multiple images on every page) and I’ve found when I batch images, if they aren’t all the same, Photoshop will stop the process on the images that are different. So batching ends up taking just as long as it would weeding out the handful that are not already CMYK and changing them manually. It is sounding like that is the only option though.

    We always leave the images “as is”. When outputting to print, we use pdf/x-4-CMYK (to be found on eci.org) option. That way no flattening, transparency is preserved.

    We use the “conbvert to profile” solution every time.

    We have 10.000 + images, that are used for web, screen, and also for printing, and we convert to CMYK in the making of the pdf.
    All our images are RGB. Hwen we need to use thise images for printing in CMYK, in out many catalogues, we do this:

    In “Output”, we choose “Colour conversion”, and choose “Convert to destination”, and then choose the correct color prifile – we use “Coated FOGRA39 – and then choose “Include destination Profile”. The pdf wil be in CMYK.

    The output is 100% the same, as if you convert the images in PhotoShop. It is the same engine inside InDesign as in PhotoShop.

    We have testet it, and the quality is 100%.

    To export an PS-file and then destill it, is wery, wery old-school …

    Thank you @Niles! I have gotten many responses where I have asked this question other places and this is the response I was looking and hoping for!
