A PostScript solution: create a dvips header file for course rasterization: %! /bop-hook {53 45{dup mul exch dup mul add 1. exch sub}setscreen} def These numbers (raster frequency and angle) are probably ok for 600dpi; otherwise, experiment a bit. Call it coarse.pro and give dvips a parameter -h coarse.pro -- Siep Kroonenberg [EMAIL PROTECTED] _______________________________________________ ntg-context mailing list [EMAIL PROTECTED] http://www.ntg.nl/mailman/listinfo/ntg-context
