I have only used kopykake frosting sheets, which is only a handful of times mind you,and my question is about printing. I seem to have trouble getting "true" colors especially red! I have tried changing the settings with the computer and it always is more brownish red than a true red. Customers were always happy but still bugs me so I don't promote that we do the images. I also put them on a dried cookie with karo or piping gel.
