    ritch balck discoloring white object

    CoGordo4 Level 1

      Hi everyone. I seem to be having a little problem with indesign and ritch black. I am making a flier that has a black background. The first time I printed out the black was a little weak. So I changed the black to a ritch black c=100 m=o y=0 k=100. Now everything that is white or even slightly transparent has taken on a blue hue. I have done this sort of thing many times in illutrator and photoshop and have never had this problem. I have checked my blending modes and everything is set to "normal" . Does any one know why this might be?  I am using Indesign  CS6  on mac os 10.6.8

          If your file is to be printed CMYK, try setting your rich black to 40c30m30y100k. That will give you a nice 3/c gray for the black to lay on top of. Can't say if that will totally solve your problem but that's the formula we always use for rich black.

            Thanks for the insight. That mix seems to work well.  It's odd this problem only happens for me in Indesign. When I do similar effects in Photoshop I dont seem to have that problem.

              Applying a rich black is a good idea for going to professional printers. But it's rarely a good idea when printing from a home printer/digital printer.


              I find it best to go the Edit> Preferences and in the Appearance of Black change the output to Rich Black.


              You can then leave the Black as 100% black in the layout - and output to an RGB device as Rich Black.


              NOTE: This only affects RGB devices (regardless of whether it uses CMYK or RGB inks the device is inheritently RGB)



              In regards to Photoshop - it's not the same as Indesign, that's why it doesn't behave the same.
