Hello all. I have been screen printing for about 2 years now. I bought a 6 color 4 station press and just sort of jumped in. My business is growing, I really can't complain. But I learned by watching a dvd....and it gave me the basics, which is what i've needed until now. The longer I am in business, the move customer seem to want and need. I'm just wondering if anyone has any ideas on how to continue my screen pringing education? Should I take a class somewhere? If so, where? Should I buy another dvd? Which one? How have other peole figured this all out? I'm talking about half tones and 4 color process stuff. Any help would really be appreciated. Thanks!!!
