Abstract: For screen printing, the screen is manufactured and used for printing in a single box. The screen material is coated with a delayed light sensitive emulsion, dried and assembled with a film opaque positive on the outer surface of a glass plate forming one side of the box for exposure to a flood light within the box, with the emulsion delay permitting assembly in normal environment light; the screen may be held down by a resilient foam layer, rigid plate and U-shaped member adjustably secured to the box for this purpose and further to serve as a carrying handle. Thereafter the exposed screen is washed and placed adjacent the outlet of a blower inside the box for the purposes of drying (the emulsion is originally dried in the same manner).
