Gradient white lines in .eps file

Feb 5, 2013 9:04 PM

Tags: #illustrator #eps #print #gradient

Hi there,

 

I designed a vector in Adobe Illustrator CS6, but when saved as an .eps file, white vertical lines appear in my gradient.

What is happening? I've tried rasterizing the vector at 300 PPI with anti-aliasing, but the edges look jagged (but I really want to keep it as a vector anyway)

Does anyone have any idea what I could do?

I don't know whether it's relevant, but I'm using process colours (but that's only because I couldn't get spot colours to work properly).

Thanks

    What are your settings for saving? What are you viewing the eps file in?

     

    Top is the AI file, bottom is the placed EPS I created from it.

    What EPS settings? Such lines appearing means the gradient has been expanded to a bunch of fill shapes and that usualyl only happens if you chose some option that would require this...

    The lines appear if I place the file in Adobe Photoshop. If I open the EPS file in Adobe Illustrator though, the gradient is as smooth as a baby's behind.

     

     

    of course it is. When you open this EPS in Illustrator, you don't really open an EPS, but the AI part Illustrator embedded into the EPS file in the first place.

     

    Photoshop is not a suitable tool for "checking" an EPS file

    EPS ist not suitable for most modern workflows either. In case you really need this for transferring your logo to Photoshop (or any other Creative Suite app), simply save an AI file (with PDF compatibility).

     

    In case you need the EPS for exchange with other software, please tell us which options you chose on saving the EPS.

    This is what I get with those settings in PS. Whether I use CS5 or CS6, whether I use EPS versions back to CS during the export:

    When you open your file in PS, are you dragging and dropping, or using File Open?

     

    Take care, Mike

    uncheck the "compatible gradient". Then gradients won't be separated into objects.

     

    But might cause issues with the client's application or printing hardware.

    My export used the same settings as the OP. The PS screen shot doesn't show the white lines.

     

    Would be good to see a test file that exhibits the issue to see if it was built differently (which I doubt).

    My test: artwork created with (top) and without (bottom) the "compatible gradient" setting. Then placed into Illustrator:

    Whether I place or open and using your file settings into PS, the file appearance is the same, here. Uncheck the setting Monika shows and see if that resolves the issue for you.

    Yes, it is. This splitted gradient was the way Illustrator used to work back in the eighties (and maybe the beginning of the nineties). Printers that can only handle files that old-fashioned way will still need the setting.
