I have a very large document [more than 500 pages] created from a variety of legacy indesign and pagemaker files. I have assmemled various chapters into 1 book and exported that to pdf.
teh pritner jsut came back to me with a request to change to 1 color black instead of RGB and CMYK. The document is black and white only - there is no color. Some text is gray and some is reversed out as white.
From scouring the forums - I understand that it has somethign to do with transparency blend space- have set that to cmyk.
Also, I have found that in Acrobat 10 - using -tools - print production - convert colors - and choosing a greyscale for conversion profile should do the trick.
Is there no way to ensure creating teh correct output in inDesign? no global export option?
I am using CS 5.5 in Windows 7
Are there linked images in the file? I run into this sometimes with images that look like greyscale, but are actually RGB. I find them by turning on separations, and turning off the black plate. With the file view reduced, it's easy to see where the errant colors are coming from.
no linked images - just black and white and grey text. I've never had this problem before! I'm thinking it is because of the mismach of source files dating back to pagemaker that I worked form. Is there not a settign in InDesign to ensure that black is jsut black - not cmyk black?
I don't know of a setting, but you could try this:
In your Swatches panel, choose "Add Unnamed Colors". This should add all the various blacks from the source files. Then just delete all the blacks except the default one from the doucment. There will be a dialog that asks what to replace them with; choose the default black. As long as its icon looks like this
you can be sure that it is made of black ink only.
I have tried that - there are no unnamed colors - it seems that the basic black is cmyk black and although there are no values for cmy - it shows up as cmyk - Is tehre nothign I can do to fix this? I can't delete teh basic black - how can I change it to black only?
If black is converting to 4-colors then there is a profile mismatch somewhere—you're exporting using a destination profile that conflicts with your document's profile, or you are including profiles with the exported PDF and your printer is inadvertantly making the conversion. The simplest solution is to use the default PDF/X-1a preset, which sets the destination to Document CMYK and does not include profiles.

InDesign has no grayscale color space. Colors can only be CMYK, RGB, or Lab.
There's not a problem if black is exporting as 0|0|0|100 CMYK—your printer can simply output the Black separation.
The little calendars are individual pdf files - i have found that I can convert them to black only by using tools-convert colors- color destination - and choosing grey gamma
then when I check teh separations - there is only black. It would have been nice to control this within InDesign though
If a placed file is RGB, InDesign can't do anything about that. The file would has to be made as only black in its original program. I run into this from time to time with files created in AutoCad. I have to convert them to greyscale in Illustrator.
not so - pls see my previous answer to myself - I can do the conversion in acrobat 10 - actually - it is tools - print productio - convert colors - conversion profile - then from drop down list - way at teh bottom - tehre is gamma grey. I shoul d have been more clear - tha t I am using acrobat 10 to do the conversion.
