Well, i did wanted to use multiple media's. For that reason i bought the dtp41.
I have a few more printers and was able to use standard profiles without a issue. I thought with such a machine i could improve the results from my z3200 and epson and also create profiles for my roland.
Also, the costs of this machine was 1/3 of a one time proffesional.
But it seems it is harder than i expected and assumed.
