Inexpensive Dry Blueprinter / Copy Machine.
To make a copy all you need is special paper, an original and a printing frame. Then, after a few minutes exposure to sunlight, and a brief developement you can have as many exact 8 1/2 by 11 inch copies as you want.
This printer is ideal for making copies of letters, runnning off a batch of posters / fliers, or reproducing plans.
With the printer on legs and two 20 watt black light ( ultra-violet ) fluorescent lamps beneath you don't even need sunlight for developing.
The fumes of ordinary household ammonia develop the paper in just a few minutes. The paper can be purchased at drafting supply / art stores in black, blue or brown line ( in a variety of printing speeds ).
Three pages ( 2 sheets - front on the first and front and back on second sheet. ) B & W photos, illustrations, expanded view and instructional narrative.
My plans are from original source materials such as books, magazines and other publications and the pages are carefully removed.
