Abstract
Abstract A device and method for setting copy comprising placing various copy, in the form of indicia-bearing material, half-tones, or other art work, onto a translucent plaque having an electrostatic charge thereon. The copy is capable of carrying the electrostatic charge such that it is removably positioned thereon yet maintains the desired position until further processing. A photographic sheet is then placed over the pre-arranged copy and exposed to light transmitted through the translucent plaque whereupon a positive or negative is formed. The sheet is then used in lithography, typography, engraving, silk screen printing, sign making and similar technologies which utilize photographic sheets.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
129 words
A visual typesetter comprising: a housing, a light permeable plaque mounted on said housing capable of carrying an electrostatic charge, an electrostatic charge generating means mounted on said housing and electrically connected to said plaque for generating an electrostatic charge thereon, copy arranged on said plaque, said copy being formed of a material capable of adherence to said plaque when subjected to an electrostatic charge, a lighting system within said housing capable of transmitting activating light through said plaque, a lighting system activating means and a timer switch, said timer switch electrically connected to said electrostatic charged generating means and said activating means electrically connected to said lighting system, whereby said electrostatic charge generating means may be activated for a predetermined time period and concurrent with said lighting system.
Claim 2
Dependent Claim
129 words
A visual typesetter comprising: a housing, a light permeable plaque mounted on said housing capable of carrying an electrostatic charge, an electrostatic charge generating means mounted on said housing and electrically connected to said plaque for generating an electrostatic charge thereon, copy arranged on said plaque, said copy being formed of a material capable of adherence to said plaque when subjected to an electrostatic charge, a lighting system within said housing capable of transmitting activating light through said plaque, a lighting system activating means and a timer switch, said timer switch electrically connected to said electrostatic charged generating means and said activating means electrically connected to said lighting system, whereby said electrostatic charge generating means may be activated for a predetermined time period and concurrent with said lighting system.
Claim 3
Dependent Claim
22 words
The visual typesetter of claim 1 wherein said copy comprises miniature transparent placards being stored on a rack extending from said housing.
Claim 4
Dependent Claim
44 words
The visual typesetter of claim 1 further including a transparent film mounted on said plaque and being formed of a material capable of being charged with an electrostatic charge to cause adherence of said copy thereto after said copy is arranged on said typesetter.
