Masking causing ghost in PDF

365 views5 repliesLast post: 7/23/2004
I'm having a problem with masked areas showing up as ghosted lines when I make a PDF. Basically, I have an "i" where I used a mask to remove the dot and replaced it with another image. In PS, as a .psd, it looks perfect—zoomed in 100% you cannot see the removed dot at all. When I make a PDF of the file you can distinctly see a white outline of where the dot was. The mask is drawn much larger than the dot, so it's not that it just isn't fully covered. You can't apply a mask to a text layer unless you rasterize it, which I don't want to do. If I flatten the image before making a PDF (also not ideal), the problem disappears. My only other option is to draw a white area over the dot on another layer. Is there something I can do to fix this?

Thank you!

I just down loaded your file and processed it through a commercial RIP.

The file is fine.

Your preview in your PDF browser is not set to the correct settings.

Yes, the object is there. You can bring the file into Illustrator and delete it, but it's a non issue.

What setting in Acrobat do I need to make the ghost disappear? The people I'm making the comps for are wondering about the ghost they see and I just keep reassuring them that they aren't really there!

Thanks,

I see the ghost in Acrobat Reader. I only have 2 suggestions.

First try using a vector mask instead of a raster mask.

Or, if you don't ever need to change the letter "I" to another letter, just go to Layer>Type>Convert To Shape. That will still allow you to scale it indefinitely. Also, you can then delete the circle at the top using your Direct Select Tool (A) on the path.

Q: Why is it not ideal to flatten your image before saving as a pdf?

Aaron,

Thanks for the tips on masks. As for the flattening, people I email the pdf to often want to print it at an enlarged size. Flattening it means that when it's printed larger, it gets jaggy. Right now all of the components of the logo are type or vector shapes, so they scale beautifully when printed larger out of Acrobat—but only if the data isn't rasterized first!

Well then, just convert your "I" to a shape (Layer>Type>Convert To Shape) and remove the dot at the top. then you won't need a mask, it will still be vector, and life will be good. :-)

Just save the original "I" as a text layer and hide it.
