    Placing Grayscale images into InDesign CS6

    boatsport

      I'm working on a book file that includes many black and white pencil illustrations. These images start in Photoshop CS6 (grayscale) and are placed in a InDesign CS6 document (CMYK). Since it's a CMYK document the gray tones are altered.

      Are there any tricks to working around this?

      The only other option I can think of, is pull the black and white pencil illustrations into a CMYK Photoshop document. But I'm afraid to do this, as I may be subject to the blue or purple tinting of all the images...

          Your gray values are transfered to the K plate in the working CMYK profile. Turn on Overprint Preview to see an accurate preview of how they will print.

           

          If you want to see the same thing in Photoshop that you will get after placing in ID you can create a custom Color Settings file and set the Grayscale profile to the black channel of the CMYK working space.

            Thanks for your quick responce Peter! I like the Overprint Preview idea, this made things appear how I would expect it to look. After viewing the doc file after it's been exported to pdf, the images are all darker again.

            Interestingly, when I convert my grayscale images to CMYK in Photoshop and place it into InDesign everything works, looks, and exports beautifully. I just don't like having to work in CMYK if I don't have to.

              The change is how the preview is managed–the actual output values don't change in PS, ID or Acrobat.

               

              If you want the Acrobat preview to match your ID Overprint/Sep Preview, open the Acrobat Output Preview panel and set the Simulation profile to match your ID document's CMYK profile.

                Wow Rob, that was very helpful! I've never gone into that area of Acrobat, nor did I know if even existed, haha! But that's pretty huge, Thanks!

                 

                I'm afraid that still won't help me with importing a grayscale image into a cmyk InDesign file without any shift in gray tones. Since cmyk to cmyk works seemlessly. It would likely work the same with grayscale. In otherwords I believe the new question would likely be "Can I create a true Grayscale InDesign file?".

                  If you place a grayscale it is still a grayscale object, but Separation Preview shows its output values  on the Black plate—if you place a grayscale PSD filled with 50% gray into ID it will read as 0|0|0|50 in sep preview. It's because ID doesn't have a grayscale color space.

                   

                  If you want to output the 50% gray value unchanged, choose Separations as the Output Color and print the process black plate. If you choose Composite Gray then the values will change because 0|0|0|50 CMYK doesn't necessarily convert back to 50% grayscale—depends on the profiles used.

                    I really appreciate your feedback Rob. I think I'm finally getting to understand this! Thank you SOO much!! AFter some thought it does seem logical as the reason ID doesn't have a grayscale mode per say.

                    Now I just need to figure out the things you're saying because this is hitting more topics that I have not had much exposure to (yet).

                    Thanks again Rob!

                     

                    Here is the answer to my problem:

                     

                    The change is how the preview is managed–the actual output values don't change in PS, ID or Acrobat.

                     

                    If you want the Acrobat preview to match your ID Overprint/Sep Preview, open the Acrobat Output Preview panel and set the Simulation profile to match your ID document's CMYK profile.

                     

                     

                    Many thanks to those who have tuned in and taken the time to think about and answer my question!
