  I have a blue blurred object against a black background all created in photoshop and when I go to print there is always this light almost gray halo where the blur is. Anyone else ever get something like this? How do you fix it?

  Does it print like that when you flatten it?

  Is your document in CMYK? If so - is the black 100%K black, or rich black?

  • It's a rich black c60 m40 y40 k100– voiceof

  Is the blurred object an eps? I've had something similar and for me it was a pixel issue meaning the printer couldn't figure out how to print all the different shades. Sort of like a low res image produces problems when it fills in the pixels in between with an average. Totally depends on what you're doing but I'd make the blue object on its own and put it on a black background in a different program like Illustrator or InDesign. Photoshop isn't really meant for design, its for photo. I'd go vector but thats just me.

  • Unfortunately I can't do it in vector and the final image was created in PS but placed in Indesign.– voiceof

  Try adding a slight amount of noise to the blurred object.

  Are you printing it on a laser printer?

  • No I saw this in the color proof from the printer– voiceof1/2

  Well I experimented with the different blacks and it looks like it is picking up the C M or Y from the rich black. For instance if I eliminate C and Y it shows more magenta etc... Do you think going C100 M0 Y0 K100 will produce a good black?

  The definition of *good black* depends on its context in the rest of the image, mate.

  • This is true. Fuck it I'll send it with just cyan and black– voiceof

  create as much of the file and background in photoshop as you can then use indesign for text and you should be good. thats what i do.

  • and I am god.– epete221/2

    That's what I'm doing this is just the image for the cover that I'm working on– voiceof2/2

  it's going to produce a blue black, if that's what you want.
  Sound to me like the blue object is screening your black background out. Try setting the object, or at least the blur of the object, to multiply.

  Look at your channels. The transition of blue object to black background is probably causing some 'lighter than either' values on one or more channels.

  You need to go from the object's blue to darker than the object's blue consistently across the vignette on each channel.

  tbh, voiceof I'm a bit stumped. I had hoped that you'd answer 'no' to my questions above, and therein would lie your answer.

  I suspect it's a printer-side interpretation problem and as such would recommend you try and get a sample printed out on a different printer somehow. Also (obviously) check your printer driver's ok and it's setup properly, though you'd likely have encountered problems beforehand if there was something amiss here.

  All I know is that CMYK screen-side RGB proofs have this problem, but it disappears as soon as the file goes to print.

  Not much use to you, I know!

  Do the entire background (image + color) in Photoshop.

  • CS is still is still unreliable when it comes to blending modes/color matching.– 5timuli1/3

    And no, I didn't read the rest of the thread.– 5timuli2/3

    I did.
    Removing the Y and M from the black and adding a multiply behind the image seems to have improved the issue– voiceof3/3
