    RGB v. CMYK issues...

    Bruceluvia

      I'm creating an image in Ps with a transparent background to use as print media in Id. I'm finding that, to maintain my transparency, I can only do this as a PNG document. The PNG format will only allow me to save as in RGB. I need CMYK. Any suggestions?

          Recheck the cmyk requirements.  Currently many comercial printers use RBG, and only hi end 4 color printers use the cmyk method.

            Save as .psd, has non-lossy compression, and you can place in InDesign.

              Yes, when I save simply as "Photoshop" I can place it in InDesign but I lose the transparency, i.e. I get a white background. Also, I don't know what you mean by "non-lossy compression".

               

              In CS6 I have multiple Photoshop save possibilities:

              • Photoshop
              • Photoshop EPS
              • Photoshop 2.0
              • Photoshop RAW
              • Photoshop DCS 1.0
              • Photoshop DCS 2.0

              Would it matter to select something other than "Photoshop"?

                This project will probably require high end printing...

                  Try saving as a PDF and placing that in ID. But your PSD should work. In ID, check the box for the import options in the Place dialog.

                    Hi Mike,

                     

                    Thank you! This was quite helpful, as it did indeed work, but it brings me another question...

                     

                    The following indentical versions have all been saved in Photoshop to be use in InDesign for print media:

                    • PDF ver. is 11.3 Mb
                    • PNG ver. is 22.9 Mb <-- will only save in RGB (I need it in CMYK)
                    • TIF ver. was 7.1 Mb <--  this one would not maitain a transparent background and is therfore not useful
                    • JPG ver. was 2.1 Mb <-- also without a transparent background

                     

                    The only version that consistently works and prints well is the PDF.

                     

                    My question is this: Does InDesign care how large (how many Megabytes) my images are? Will my printer care?  i.e. What are the pros & cons of the file size for InDesign and when I take the project to my printer.

                     

                    Please understand that I am a relative newbie to the desktop publishing & graphic design world. I believe I would be catagorized as an "advanced beginner" and a good student.

                     

                    Thank you for any insight you can give,

                      A TIFF should save a transparent background. From a previous post.

                      There’s no transparency support in tiffs

                      That is not correct - TIFF supports transparency.

                       

                      Some other applications may not support TIFF transparency correctly, but the file format does support it, and Photoshop's TIFF code supports transparency.

                        You seem to be doing something wrong then.

                        psd supports transparency and Indesign can handle psd files.

                        Could you please post a screenshot with the Layers Panel visible?

                         

                        WIll you pass on the indd file or a pdf?

                        In the latter case working with placed rgb images is OK because one can separate on pdf export (for example PDF/X-1).

                          Make sure Layers is enabled in the Save As dialog when saving to PSD, PSB, TIFF or PDF, otherwise the file will contain an opaque flattened image.
