Message: Are you sure you want to print this document as a bitmap

Cause

You have tried to print a document using color separations when you have the option to print the document as a bitmap set. If you print color separations with the printing method set to Bitmap or Anti-aliased Bitmap, the following occurs:

All spot colors will be output as process RGB colors. All spot plates will be blank.

All CMYK colors will be converted to RGB color, and thus color-separate differently

What can I do?

Change the printing method in the Print As section in the Output Options.
