In Orcad PCB editor, version 16, I need to print top layer and bottom layer negative
(copper tracks are clear and the dark background). In Manufacturing> ARTWORK put "plot mode" in negative in the tab film control but then I do not get the result ..
A window opens with the following error: ERROR: aborting film - Layer polarity of layer ETCH / BOTTOM does not Negative polarity of film match. May be unreliable DRC.
what I can do?
thank you
 

check in cross section youhave to define top and bottom as plane there to get the negative artwork.
but do check the connectivity after you make any electrical layer to negative.
 
Thank you very much. Now I can do the top layer and bottom layer negative
 

Can I ask why you would want to produce a negative artwork in this day and age?
 

I agree with Marce if your board is not really big I will suggest you to go with positive planes only
