Plot Transparency and PDFs

[Anonymous]

I am having a problem getting PDFs to plot when I have plot transparency on.

I use the dwg to pdf plot function and with plot transparency on... my hatches work perfectly but my PDFs appears very much screened.  (As a 50% or more screen would look) If I turn off the plot transparency, the pdf works perfectly but of course my hatch shades obliterate any line work beneath them.

I was able to convert the PDF to a .tiff, with a graphics program... increase the resolution to 600dpi and use imageattach to bring that in.  But it is an extra step for each insert and increased dpi = increased file size.

Other than increasing the resolution on the PDF has anyone found a way around this "screening" issue on PDFs when plotting with transparency on?

I would check teh settings for the DWG to PDF.pc3

Go to the Device and Document settings tab and expand the graphics button. Make sure the "Merge Control" is set to lines overwrite.
