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). Printing is carried out by mounting the thus manufactured screen on a frame pivoted to the box so that the screen may be coated with printing material and engage a paper to be printed lying between the screen and a vacuum plate, which vacuum plate is at the inlet of the blower and will hold the paper on the box when the screen is removed after printing. Other material, such as wood, plastic, metal, etc. not requiring vacuum may also be printed providing they are smooth and flat. This unit will print on objects up to 3 inches thick.
