Here is the Amy the Squirrel picture for the Afit T-shirts. It was created in Hires interlace 16-color Dpaint3 page size(640x680 I think, you don't need 1 Meg of Chip ram, but it might be helpful.)
The picture and a reversed version of it(for the iron-ons) are here.
I don't know anything about inkjet/paintjet printers except that they
generally print a bit nicer than a ribbon-type. Anyway, I will give you a few notes on how MY printout tries came out (I have a Star NX-
1000 color printer, using 1.3 EpsonX printer driver,default graphic preferences settings.)
* The blues came out WAY darker than on the screen
* The two darker browns look too similar when printed out
* The light greys seem too indistinct(mainly from the wide dithering)
