In particular, thermal% transfer and direct thermal tend to be better with standard ordered% screening methods. Some laser printers may produce "smoother"% looking gray shades with Stochastic halftoning. Try it, and if% you like it, use it. % Note that this /Default halftone can be overridden by PostScript% operators that set the screening or halftone (such as setscreen). % To make Stochastic Halftone be "sticky" so that other screening and% halftone setting in the subsequent PostScript will be ignored, use:%	-c "<< /HalftoneMode 1 >> setuserparams"% on the command line prior to the file to be processed. For example,%% gs stocht.ps -c "<< /HalftoneMode 1 >> setuserparams" -f examples/tiger.ps % Alternatively, the command to set the /HalftoneMode userparam can be% concatenated to this file (see below). % =====================================================================% Try to get the previously defined resource{ /StochasticDefault /Halftone findresource } stopped{  pop pop  % Need to load the Stochastic Halftone using the lib file  (ht_ccsto.ps) runlibfile} if % If we didn't error out by now, then go ahead and define the /Default/StochasticDefault /Halftone findresource/Default exch /Halftone defineresourcesethalftone	% Use the halftone % Uncomment the next line to make the Stocahstic halftoning be "sticky"% << /HalftoneMode 1 >> setuserparams
