One other concern. As I played around with the original design to get it to work for the black t-shirt, I saw that the rhodamine-plasma color that worked so well got very muddy when I converted it to CMYK. Here is what it looks like. Not pretty.
As most print processes use CMYK, this may be the result if we use the original design. I believe they use an inkjet based process that may have a wider color gamut (HP uses a 6-color process, Epson uses an 8-color process), so itt may not be as bad as shown here. The only way to know is to make a shirt, order one, and see how it looks.
I am about to post the rest of the designs. All of these will have CMYK simulation applied.
