oh, sorry. i checked this forum TSPMB - The Screen Printers Message Board! but more importantly i called the manufacturer Rutland and talked to one of the tech guys
the above forum is great for finding out and asking questions but they also have a good selection of beginners articles for ...um...beginners
Thanks for posting that Just in case someone has a similar question and they ran across this thread, they know how to get the answer
Sometimes a quick phone call to the source is a great way to get an answer as well
