Abstract
Abstract A photographic exposure apparatus and method for preparing production artwork of an image to be reproduced by photoengraving. The apparatus includes a movable panel superposed on a stationary plate for supporting a film containing an image to be reproduced in contiguous contact with a light sensitive sheet superposed on the stationary plate. Film registration indicators at least on the stationary plate permit successive identical registration of the film and at least one light sensitive sheet. An orbital motion guide and a linear motion guide, separately connected with driving motors and separately connected with the film support panel, are selectively manually adjusted and the respective motor energized for moving the film support panel in a predetermined path of predetermined magnitude during exposure of the image on the light sensitive sheet. In an alternative embodiment, the image is projected on the light sensitive sheet when attached to the film support panel by an overhead projector.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
100 words
In a graphics modifier having a planar base, a stationary film supporting face plate overlying the base and a transparent superposed film supporting carriage panel movably supported relative to the face plate and having pulley and cable means maintaining marginal edges of the carriage panel parallel with the respective marginal edges of the face plate during movement of the carriage panel, the improvement comprising: orbital and linear motion guide means mounted on said base and selectively connected with said carriage panel for moving said carriage panel in a predetermined path; and, motor means drivably connected with said motion guide means.
Claim 2
Dependent Claim
100 words

Claim 3
Dependent Claim
108 words
The combination according to claim 1 in which said orbital motion guide means includes: a disk rotatably overlying a marginal edge portion of said base; a dial pointer overlying said disk for relative movement toward and away from a starting position; bolt means connecting said dial pointer with said disk in off-set relation with respect to the axis of said disk for maintaining said dial pointer in a predetermined position, said dial pointer having an aperture coaxial with the axis of said disk when the dial pointer is in a starting position; and, a guide mandrel supported by said carriage panel and projecting into the dial pointer aperture.
Claim 4
Dependent Claim
98 words
The combination according to claim 1 in which said linear motion guide means includes: a centrally apertured pivot plate overlying a marginal edge portion of said base, said pivot plate having a diametric groove in its upper surface; slider means longitudinally slidable within the pivot plate groove and moved a predetermined distance from a starting position by said motor means, said slider means having a central aperture coaxial with the pivot plate when the slider means is in a starting position; and, a guide mandrel supported by said carriage panel and projecting into the slider means central aperture.
Claim 5
Dependent Claim
38 words
The combination according to claim 3 and further including: clamp means securing said pivot plate to said base for maintaining the pivot plate groove in a selected angular position relative to the marginal edges of said face plate.
Claim 6
Dependent Claim
39 words
The combination according to claim 4 in which said motor means includes a drive shaft and said slider means includes: a slider; rack means supported by said slider; and, a pinion on said drive shaft engaging said rack means.
Claim 7
Dependent Claim
53 words
The combination according to claim 3 or 5 in which said face plate is characterized by at least one pair of registration pin holes indicating at least one photosensitive sheet or film position thereon and further including: a pair of registration pins for successive registration of one or more photosensitive sheets or films.
Claim 8
Dependent Claim
53 words
The combination according to claim 1 or 2 in which said face plate is characterized by at least one pair of registration pin holes indicating at least one photosensitive sheet or film position thereon and further including: a pair of registration pins for successive registration of one or more photosensitive sheets or films.
