Well, if you're a complete newbie, I would start with a one color print. It sounds like you're starting from scratch, so you may want to think of each part of the process as separate, but part of a whole. Art, onto film; screen making; press setup; printing; finishing. Perhaps someone local to you could make a screen for you so you could learn to print first, developing the touch. You ask for some tips, but there are so many, it's best to zero in on a particular topic as it pops up. Everyone here is glad to help, and we've all been where you are. So, if you're trying to output am image to film, we can explain the steps; exposing the screen, finishing that, press setup, ink mixing, the correct ink for the product you want to print on, we're here for you.
