PitStop. Running it through PhotoShop forces you to rasterize the vector objects. That's screws everything up.

Thanks Matt for the reply, but the text is part of the image, if there is a way to fix this in pistop can you please tell me. because we have a lot of spoilage.

If the "text" is part of the image then all you can do is edit it in PhotoShop. If it is vector or live "text" in Acrobat then you can fix it with PitStop.

Are your customers providing you raster images (TIFF's or JPEG's) that contain text?

If you are fixing the text in photoshop, you usually get a knockout (white behind the type), not an overprint. In photoshop, the only way the text can be black is if it knocks out, otherwise the color would be that of 100% on the black channel and then what ever percentages of color on the other channels that the background is.

That being said, to create an overprint, select the CMY channels only use the eyedropper to select the color, then select the type area and then do an Edit==>Fill, using 100% foreground color. This will work if it is a solid background. If the background is an image or some sort of a gradient, you are pretty much left with the clone tool as your only option (on the CMY channels only).

If the text is an editable layer in photoshop, you can set it to overprint by double clicking on the text layer to get the options, and changing the blending mode to "multiply" instead of "normal" in the layer styles. Just found out about this recently and it's saved much frustration on a few recent jobs.

Can you open the pdf in Illy and edit the text there?

if you can select the text in photoshop do so - mix a "black" only and fill it - this will delete the colours underneath and leave it just "black"

if it needs a spread then go select>modify>expand - (enter an amount) - and wallop - trapped black only text

hope this helps
