talking SHOP Screen Printing Technique Screen-Making Techniques, Part 1 A review of the components and procedures required to produce the best quality screens. By Rick Davis, Contributing Writer Shown here are the three primary frame formats used in screen printing (left to right) - wood, tubular aluminum and retensionable. i wholeheartedly believe that if our industry held one philosophy above all others, scrape rates (misprints) would drastically decrease and profits would subsequently increase.
