Abstract
Abstract A framed silk screen for application of two or more colors, said screen having a thin, flexible divider strip which separates adjoining color areas. The lower edge of the strip is held by a bonded joint to the silk screen. A method for making the framed screen provides forming a linear pervious area in the screen, mounting the strip so that its edge is aligned with the pervious area, and bonding the strip to the screen by means which allow bonding material to pass through the pervious area of the screen.
