f. Strip a sensitivity guide into the edge of the flat.
NOTE
Standard masking materials should always be used in making the flat. These are materials that will prevent the
exposing light going through to the plate. In the stripping procedure on the light table, however, film can be read
through the masking sheet. The film contained in the flat should be free of pinholes, dust, dirt, and tape
adhesive residue.
Since the plate must pick up fine detail such as fine halftone dots, the plate will also reproduce pinholes,
opaquing, and dust specks on the image area. Pinholes should be covered with opaquing solutions prepared for
this purpose. Film should be cleaned with film cleaner or an anti-static brush.
