Bob and all,
I've recently had a computer associated moment too, coincidence?
I'm making a set of cotton sails for the tea clipper Thermopylae, at 1/96 scale. My method is to draw the sails on the computer (simple draw mode in NeoOffice) and then print onto a paper backed cotton cloth known and sold as "lawn cotton."
I was having some trouble getting the colours correct, for me, as the printer produced printouts slightly paler colours and more faint than I wanted. I've always used the printer settings as standard Epsom settings.
The Eureka moment, when in frustration after several poor runs, I used a drop down menu that offered "colour matching." In for a penny, clicked it and printed. Resulting print out was exactly as per screen image!!!
Now all you experts will say "of course, we knew that. Why didn't you ask?" Well, I'm happy now and quite happy to share this finding with you all.
