Well Coral Draw is used by Screen Printing guys. My brother in-law is a screen printer. He does all the prints for my clothing company.
He and I make the designs in Coral Draw. He's a lot better at it. (18 years experience) Myself I started using Coral about 3 years ago. I'm no pro but I can do some things. what I can't do I draw by hand and take it to him to do through Coral Draw.
