Overprinting in Indesign/Illustrator/Acrobat – TURNING IT OFF

[argent]

Having a little issue at the moment which I will put to you guys.

Overprinting – Is there any way of turning this thing off completely? I've always been under the impression that u can turn off overprinting (when it's for some dumb reason set by the computer when converting to paths) simply by selecting the entity in question and going to the attributes window to turn it off.

However, I now have come across an entity that explicitly does not have overprint turned on in attributes, exporting to PDF and when I go and look at it in Acrobat, lo and behold, the thing is set on overprint which obviously messes things up.

Any ideas would be great and helpful – aside from going through a self created PDF with a fine toothed comb and turning off all over printing with prepress software like Pitstop or something

What do you mean by over printing?

bleed?

There should be an option in the preferences under "appearance of black"
You should be able to see a little checkbox that says overprinting. Just uncheck that.

This should be the case in both illustrator and inDesign

Cheers for that. Checked and works well. This issue has been bugging me like crazy as overprint isn't defined as a prepress issue. It seems that it's a 'per file' setting though which means it must be unchecked with each new file??

You shouldn't have to un-check it every file.

Can you show us a sample of what you are having issues with as turning off overprinting all together is not ideal? Send me a PM if you like

With the overprinting turned on 100% black will overprint all the time, and the opposite if it is turned off. Instead of turning overprinting off all together you can just knock your black back to 99% and it won't overprint any more. When it goes to print it will separate properly and any black sections you have set back to 99% will now knock out of what ever is behind it.

If you want nice rich blacks then you are better off leaving overprinting on and only setting black to 99% when you can't find any way to design around it. Without overprinting on you may find your blacks will look dull unless you also add some magenta or cyan into it to bring it back up again.
