When do you want to convert graphics to grayscale?

[stanw]

When is it a good idea to convert your artwork to grayscale to check it for contrast? Is this something you should always do or are there only some situations that this should be checked?

Thanks.

haha...not homework at all. Trying to figure out what situations I should be doing this, situations that I'm not aware of that it might be helpful...

I do this as one part of my section 508 compliance testing for colorblindness. If you do any work for government agencies it is a requirement, tho its a smart idea to do it anyway. Colorblindness is the most common disability in the United States.

For the purpose of photocopying.

Low contrast images look like crap when photocopied.
