Generation of Art Work on a Printer

In creating the art work for printed circuit cards, considerable time is spent in taping the original enlarged layout which is then reduced to the desired size.

To speed up and simplify this procedure, the necessary data is fed into a computer under program control. The computer, in turn, operates a printer using special type to print continuous line art work and legible characters at eight times normal size. When appropriately photo-reduced, an actual size film master is obtained.

Six character fields of a ten character per inch, 15 line per inch printer, are shown arranged in a two over three grouping and occupy .200 x .200 space on the paper. This area has been chosen to represent a .025 x .025 increment of the actual size art work. Having to associate three carriage space lines (horizontal) with two character positions (vertical) is not convenient from the viewpoint of symmetry. However, two carriage space lines coupled with two horizontal character positions of a hypothetical ten LPI printer would provide evenly scaled 1/10" type fields which could conveniently be used alone or, as noted below, combined to form larger basic output patterns.

A ten LPI printer is simulated on a 15 LPI carriage by employing .100 x .100 type fields offset with respect to the first and last printing line of the 2 x 3 print matrix. No printing is required on line two to fill the .200 x .200 program matrix. Automatic double spacing of the second, fifth, eighth, etc...
