    InDesign Pdf colors don't match the CMYK jpg in document

    sukimd Level 1

      I created a document in RGB in PhotoshopCS6, and then converted a jpg from that in a duplicate copy of that document as a CMYK image. I brought it into an InDesignCS6 document and exported as a Print PDF and the colors are much paler than the original JPG.

       

      I've looked through the boards here and other online forums, but nothing suggested is working. I've tried different color profiles in both photoshop and indesign and nothing has worked. If anyone has any advice or could help in any way it would be much appreciated (even if it is something I might have missed using color profiles). I haven't had this issue with any other pdfs before so help would be much appreciated!

       

      Thank you!

       

      Edited to add images of issue:

       

      The first is the much paler PDF:

      The second is the original, correctly colored JPG:

          You don't "try" different profiles, you make sure it is the correct one throughout and consistently. The correct CMYK profile is the one that corresponds to the actual printing process. The printer should tell you which one to use, and if you don't have it installed, download it. Ask them!

           

          Don't use Image > Mode in Photoshop. It gives you the false impression that there is some "generic" CMYK, which there isn't. In fact it is just a profile conversion into whatever you have set up as your working CMYK. By default that's US Web Coated SWOP, but that may not be the correct one to use.

           

          For images, work in RGB and place RGB in InDesign. Convert to destination CMYK - the correct one - when you Export to press-ready PDF from InDesign. This way the document can easily be repurposed for changing press conditions.

           

          You can use Photoshop to proof to process CMYK. This will tell you if there is significant gamut clipping in the conversion, and show you what that clipping will look like. You can then decide whether you need to tweak the original file to compensate. That is not required, just your call to improve appearance if it seems worthwhile.

            Hi Susannah,

             

            I don't think I have understood 100% what you have written - but I'll try help -

            please help me by explaining more fully what you did here (see below):

            "I created a document in RGB in PhotoshopCS6, and then converted a jpg from that in a duplicate copy of that document as a CMYK image. I brought it into an InDesignCS6 document and exported as a Print PDF and the colors are much paler than the original JPG."

             

            Ok, so you

            1:

            you "created a document in RGB in PhotoshopCS6"

            - what RGB setting (the ICC profile) please?

             

            2:

            you "converted a jpg from that in a duplicate copy of that document as a CMYK image"

            - so, am I right - you duplicated the document and converted the duplicate to CMYK,

            how did you do that conversiion? there are 2 main methods:

            A: image/ mode / CMYK

            - or - 

            B: "edit / convert to profile"

             

            A would use the CMYK profile which has been selected in edit / color settings (what is that please?)

             

            B would use whatever CMYK profile you select (this should be the CMYK profile specified by your printer.) what did you choose please?

             

            *important note

            there is no "generic" CMYK, ideally you'd know what the printer wants then choose that CMYK profile.

             

            3:

            you "I brought it into an InDesignCS6 document"

            - so you imported the image into an InDesign Document

            in InDesign have a look at edit / color settings

             

            4: you " - exported as a Print PDF."

            - did you select the Adobe PDF preset "high quality print" at the time of export?

            within that preset you'll see in section 4: "output" that this is setup for "no colour conversion"

             

            what "no colour conversion" means is that the image file which you imported will retain its CMYK characteristics,

            i.e. it doesn't get converted.

             

            *note

            [that’s why, when intending to make print ready PDF's  and placing CMYK, it's important to place images which have been converted to the right CMYK colourspace ( using the ICC profile your printer specifies)]

             

             

            So, you have 3 images and unfortunately there's a visual difference between them

            1: a document in photoshop which is RGB

            2: a document in photoshop which was converted to CMYK

            3: a CMYK file placed into InDesign and exported as a PDF

             

            where are the differences?

             

            with what application are you viewing the exported PDF?

            That’s pretty vital to all this.

             

            I hope this helps
