HELP!
veeofasa (12 points) | Tue, 2006-08-22 19:15I have two questions. I am creating a program for a non-profit. It is going to print in black and white. The ads I have recieved are all Quark documents in RGB. I have Indesign. Do I need to convert them to grayscale and how would I do that.
My other question is do I need to specify in Indesign that the file needs to be black and white.
Thanks!

The ads are pdf's from Quark
You can use Acrobat 7 Pro to convert the RGB PDFs to Grayscale.
Open each ad in Acrobat and select 'Tools: Print Production: Convert Colors'.
From within the dialog choose to 'convert' the file to destination space 'Gray Gamma 1.8 MAC or Gray Gamma 2.2 PC' [Very Bottom]
This will dump all of the color from the PDFs before importing them into your InDesign layout.
WARNING: This operation cannot be undone so save a copy of the file before using a procedure like this.
---------------------
Technically speaking you can leave the RGB conversion up to the printer. During output they can convert all of the color to a composite black plate. You just have to watch out for colors like RED or ORANGE next to dark areas or yellows against a light background. [Yellows convert to a very light gray and reds and oranges convert to about 75% - 85% gray] In my opinion it's best to deal with any issues before you deliver files to the printer.
