I have several documents with black filled shapes that are not printing correctly. The black prints more dark gray and is not solid. I have tried several suggestions from other posts such as 1) Output all black Accurately, Change to a rich black, output to PDF and then print. I'm still getting the marbly looking black. Any help?
How are you printing?
First, black that is only 100% K with no other colors mixed in is going to look gray compared to a rich black. Second, large solid shapes can be difficult to print evenly under the best of conditions.
