Whenever I plot to PDF (using DWG to PDF.pc3) PDF underlays in the drawing appear faded in the resulting PDF. If I plot from the same file in acad 2011 the PDF underlays appear normal. Any ideas?
Contrast for the PDF underlay is set to 100 and fade is set to 0.
I am not sure I understand your question.
Do you already have a PDF underlay when you create a new PDF?
Can you send a sample file with the steps to reproduce?
Are you using the same plot style configuration in 2011 and 2012?
