You can get fabric sheets for regular ink jet printers which I've used for other projects, but that wouldn't give you the right texture for the scarf and I bet it would be impossible to get the deep saturated colors right. It would also be really expensive considering the cost of ink jet ink. There is also silk screening, but I don't know how to do that plus you run into the texture problem again. The dyeing is certainly time consuming, but it's not all that expensive and I can fine tune the colors as I go along. I like not having to deal with any machines or special supplies beyond making sure I don't run out of dye.
Sculpy is good stuff, but when I modify a head, I usually use Magic Sculpt which is a two part resin that air dries but has a nice long working time and has the real advantage over Sculpy in that it doesn't have to be heated it in any way to cure it. I get little 2 oz. tubs of it from eBay and that's more than enough to modify any number of heads.
