I am very new to Indesign. Just started working with the program a month ago and it is an older version (Indesign CS2). I am designing ads for a magazine that originally were to be in color. However, they are now needing to be black and white. I did not know if there was a way to change the work I have done to greyscale?
I cannot find any information in my indesign for dummies or just browsing on the web.
There's no easy way to do this. You can delete all your coloured swatches and replace with black — but that only gets you part way there.
Any coloured line work and panels could be copied to Illustrator, converted to greyscale and copied back — but that's only efficient if you've got a lot of it. Imported ai and eps files need to be converted in Illustrator.
Photographic images need to be corrected in greyscale to get the best results (just a straight conversion is seldom good enough).
Probably not the answer you were hoping for.
Good luck with it.
