I have printed pictures for years and have used many of the different prepared fabric as it came out. My favorite is Printed Treasures. What I have found is that I get the best results if I over saturate the colors on the picture to print on the fabric -- remember the fabric is more absorbant than the paper or picture paper. I have a simple picture processing program and DH hates the looks of the pictures before I print them. I get some vivid colors and they hold the color very well. Printed Treasures has a decent hand -- it drapes well and holds the colors.
I have not made my own fabric for the printer so I don't know how well it holds up.
