The PostScript Language Reference Manual says that as each painting operator is executed, "each new mark completely obscures any marks that it may overlay. This method is known as a painting model: no matter what color a mark has ... it is put onto the current page as if it were applied with opaque paint." My question is, is there some way to "or" a mark onto the page? I want to superimpose a large grey "DRAFT" on top of an already composed page, but the letters of the word "DRAFT" are covering up the text behind them. I can't image the "DRAFT" before the page is painted because then the "DRAFT" gets obscured. It's probably possible to set up the appropriate clipping path and then draw a whole bunch of dots, but it seems like there ought to be a better way. Hoping my question isn't incredibly naive, -David Hull
