From: Mason C on 14 Jul 2007 16:16 I have maps with gray nations. For the printer these need to be halftone. I can laser print and produce a halftone, then scan at high resolution to get a halftone image. This works in principle but not very good in practice on my machines. Is there any way to convert gray to halftone directly in PSP? I know the "reduce to two colors" is a possibility but the printer may not like Stucki, Floyd, Burkes dots. If my printer can make halftones, why can't PSP? Mason C

You have chosen not to reveal your version, but PSP 8 and later set the screen properties with this Effects > Artistic Effects > Halftone. There's a plug-in for earlier versions. -- Fred Hiltz, fhiltz at yahoo dot com

I'd make up a test image of combinations of the 3 x 2 selections and print to see which reduction creates the most pleasing effect on your printer. And be sure to print at one pixel to one printer dot to get the best effect. Set the size of the image first, using your printer's dpi value to set the PPI value in PSP. Then do the above conversion.

I had looked in Help for "halftone" and found nothing so assumed there was nothing. I might never have found it. Thanks ever so much for all the time you've saved me.
