    Problems exporting an RGB file as PDF

    Anamaria M

      Hello,

       

      Here is my problem.

       

      I made a 10 pages file in InDesign, RGB space designed for web. Created some masters. After exporting (smallest file size as well as others too) to pdf the result gives me different tint of colour on pages even if i used the same master. So, if page 2 uses Master A and page 4 uses the same master A, in pdf they have a different color, more like they have a different color managment.

       

      Please help me with this issue and sorry if i couldnt explain very well.

       

      Ana

            No Eugene, it isnt checked. I also tried to check it and export it again. The same result.

              PsrtScr_example.jpgI dont know if this will help. I tried to change the files from master, from psd, to tiff  to jpg. Still the same result. So, is nothing wrong with the files, more likely with a setting.

                So look, here it is a print screen from the pdf. Up is the page with wrong colour. Page 1 uses the same master as the page 3 below (at page 3 you wont see number in this print screen) but their colours differe and I dont get it why. I still need this file the same colours everywhere and the right colour is displayed at the page at the bottom.

                  I'm not seeing a lot of difference in the color on my screen, but My guess is there is transparency involved on some pages and not others, and the the transparency blend space is set to CMYK instead of RGB.

                    Sorry to come again, but no, transparency blend space is set to RGB.  About other transparency things I didnt find yet. Still sreaching. Thank you for your help anyway.

                      So just what color is wrong in the screen capture?  Are you sure this isn't a monitor issue? We had a user a few weeks ago with a monitor that displayed color unevenly from top to bottom.

                        So in the screen capture, ive got up 2 pages, and down, another 2 pages. From left to right up is cover 2 and then page 1, then down, page 2 and page 3. The psd files Ive used for all masters are the same, using the same color space, using the same save options. Up, the green displayed for both background images is lighter and looks more like a CMYK green. Down, the green displayed is the RGB correct green. As i checked many times psd files are good and is nothign wrong with them from what I saw. There must be something I do wrong or I didnt notice in InDesign. As I said, space it is set for RGB, blending mode it is RGB and I do not use any other transparency objects on any of the page. So, Ive got only the background images files, and text from indesign, that is all. Still, I might do something wrong and I am not aware of, because I work usualy only for offset printing purposes, not for screen purposes set as RGB.

                         

                        My monitor behave the same as the example you gave, unevenly from top to bottom, still this is one of the first things I check if I see something wrong with colors, being aware of monitor behaviour.

                         

                        As you said the difference is not that big, but it still is and bothers me as long as I want to look everything the way I designed. Not important for this topic, still I am explaining to understand why I need everything as good as it can be. The final pdf file will be available for download on a website I design for an artist. She created an art character who has a background story developed. It is a special page on her website, designed only for this character with his story. The site will be seen in some expositional spaces by many people, so, for this purposes, I really need everything to look good, without evident issues.

                         

                        Thank you.

                          Turn on Separations Preview (Window > Output > Separations Preview and choose Separations from the dropdown). Put the cursor in an area that should be the same on both pages but looks differnt and check the numbers to see if they really are different.

                            Ive checked. In numbers they are the same. If you agree and PM me your email address, I can send the pdf file.

                              Anyway, thank you, ive turned out every file into jpg and works just fine. Still, why behaved like that when one of the master was psd. because it was screwing the page next to it also.

                               

                              Thank you anyway.

                                If the numbers are the same and the appearance is different, it is the monitor. It should make no difference if the image is saved as .psd, .tif, or .jpg (except that .jpg does not support transparency).
