This application will alter the standard Gutenprint definition files to enable them to print 1) A white under-base and 2) A three color composite image for use with direct to garment printers. If you're looking for a free Epson RIP then this is the closest you will ever get.
The second component of this project will be a plugin written in C# for Gimp that will create two layers from an image. One for a white underbase and another for the image to be printed on a garment.
Please send me a message if you are interested in being involved.
