Hi there. I've been playing with the Gimp for the last couple of
weeks and I found it an amazing tool, however when I tried to
output my designs to my postscript printer I found that I can't
setup screen angle for the printing, which I need for my business
(screenprinting). does anyone knows how to accomplish this within
the gimp?. I googled but couldn't really find anything.
Yes, as a matter of fact, the GIMP doesn include support for
professionall printing.
I am really sorry for that. Thre is one possible work-around: the
screens can be generated as a GIMP image with the
filters->distorts->newsprint filter.
However that is mostly meant for special effects purposes than for
actual generating of screens. You would have to:
Enlarge your image so that the pixels will hold the screen dots itself
on your printer (let's say 77 LPI on a 600 DPI printer -> 7.8 pixels
per scrren dot ..so you have to create an image 8 times as large as
one that would hold one pixel for screen dot)
Make a b&W version of each channel of your image (through
image->mode->decompose), followed by a invert
(image->colors->invert ) on each decomposed layer.
Finally filters->distorts->newsprint , cmyk, only K channel matters.
cellsize, for this example, would be "8". after this one, convert to
b&w, and print each layer separately.
Sounds painfullllllllllll... Maybe the newsprint plugin can be changed
to have an option to do it's stuff into separate layers, and keep
colors as black - that would short the work-arounding cycle a lot
I will offer yopu another option however. I intend to work on
something for the postscript file saving in the GIMP (not printing).
So, if you could, run through another application, print a __small__
(32 X 32 pixels would be nice) file, with your color corrections and
screem parameters all turned on (be sure the picture, small as it is
have all 5 of CMYK + white) colors.), and send me this gerated PS. I
could be able to add the screen options to the GIMP file save as
Postscript plugin (not gimp printing).
