We produce photomasks by changing the colors of the desired features to black and using the Plot command. This works well for most of the etch but not for dynamic shapes with solid fills, which print gray instead of black. Connect lines and cross-hatched fills print black but a solid fill does not. The gray is very dark and looks like black in Plot Preview on the screen but emerges distinctly gray from a laserprinter. The darkness varies between printers. Printing to pdf with Distiller gives a shape that looks black on screen but again becomes gray from a printer.
Can anybody suggest how to make the fill genuinely black, please? I am using OrCAD 16.3 on Windows XP.
Why aren't you using Gerber and processing the Gerber film instead?

In reply to John Davies:
The solid plot is possible from PCB Editor directly. You could have enabled OpenGL from main menu Setup->User Preferences->Display->Opengl the disabl_opengl value could be unchecked. Than could be checked value in display_nohilitefont Setup->User Preferences->Display->Highlight. Last step is setting the number of lines spacing for shape fill Setup->User Preferences->Display->Shape_fill display_shapefill set value 0. It is not clear but might help.
In reply to Zbynek Holub:
Thanks a lot for this information.
It works for me too.
I use PCB Editor 16.6 and I don't set the number of lines in value 0 in Setup->User Preferences->Display->Shape_fil , I only can enable or disable this parameter.
Thanks for your help.
This post will not answer your question. However, I do want you to know you are not alone with oddball plotting problems. I have had so many different little things not work properly that I now will only create Gerbers and them plot them. My favorite failure is turning on the primary side etch, looks right in preview, prints properly. Then I turn off the primary side etch, turn on the silksceen layers, looks right in plot preview, the actual plot scales incorrectly and cuts off a lot of the silkscreen to the right. CAM350 is so worth the money for what I do.
In reply to BuddSw:
I had the same problem and with the next change its running ok.
Go to the menu bar SETUP --> User Preferences --> Display --> Shape_fill.
For the variable display_shapefill put 0 inside the VALUE field.
Apply and OK.
