Go to Window>Output>Separations
And switch from off to Separations.
Turn off the Black plate
What does it show?
Can you post a screen shot of what is happening?
Eugene, in Acrobat the text shows as knock-out, irrespective of which settings I use in InDesign pdf export UI panel. Tried also exporting as eps and exactly the same result: black will not overpint. InDesign default if black always overprints unless you deliberatly change. One question in my mind is: does Indesign uses its own pdf creation engine or relies on Acrobat driver. Thanks for you input.
I want to know how it looks in InDesign in the Separations Panel - can you check that please.
Have you added any transparency, from the Effects Panel?
Can you provide a sample file?
Black in InDesign is set to Overprint at 100% and it should not Knockout.
It's very hard to diagnose the problem with little information. So I want to see how it's behaving in InDesign.
And it's very hard to know why it's knocking out in Acrobat - without knowing your PDF settings, although I can't think of a setting in creating a PDF that would change how the Black prints, as overprint or knockout?
Sorry Eugene, I cannot access the macintosh computer at the moment. Here is late at night and the office is close now. I can tell you that if a print the same file to a lase printer as separation it is fine, so the issue is not actually with Indesign but the export plugin that either is overriding the defaults or some other setting that I cannot pinpoint at the moment. I will get the screen shot as soon I can. (By-the-way, the pdf setting I use are as simple as possible since the workflow we use at work doesn't warrant anything special: press quality, untagged, no compression and no color conversion)
No reason I can think of that the PDF would have the Black at knockout.
You're definitely using the default Black swatch named [Black]?
Just tried there with your PDF settings, and it worked fine, the black overprinted no problem.
The only things I can think of is that the Black was not 100% tint.
It used a transparency from the effects - with isolate blending ticked
It's a total guess though, I'd have to see an example of the file.
If you can provide:
Example INDD file
InDesign go to Adobe PDF Presets and Define... and SAVE the PDF preset and upload that too
That would be great.
I have recreated the preferences file but no difference.
At least half the time someone says this it turns out they only dragged the InDesign Defaults (ore the folder containing it) to the trash. ID's prefs are a two-piece set of files, stored in two different folders, and you almost always need to to replace both halves, either by using the keyboard shortcut on startup or by manually removing both files. see Replace Your Preferences
If that doesn't do it, my guess would be your installation is damaged and I'd suggest you uninstall, runt he clean tool (Resolve installation problems with CS5 Cleaner Tool) and reinstall.
