Hi. I'm very close to purchasing a 6-color tshirt press. I'd like to use it for printing both tshirts and posters. I've read in a couple other threads that some of you also use tshirt presses for printing posters. So, I'm hoping this will work for me. But, I'd love any input or opinions before making my purchase. Specifically, I'm wondering if there is any reason not to go with a 6-color press? I'm a bit worried about ink drying too quickly. Would any of you recommend a 4-color press instead?? Thanks.
