<p>Photographic exposure apparatus and method for preparing production artwork of an image to be reproduced by photo-engraving. Prior art handwork or manually operated devices employed in modifying artwork images required high levels of skill and considerable time to achieve satisfactory results. The subject apparatus includes a movable panel (12) superposed on a stationary plate (8) for supporting a film (135) containing an image to be reproduced in contiguous contact with a light sensitive sheet (138) superposed on the stationary plate. Film registration indicators (28, 30, 32, 34, 36) at least on the stationary plate permit successive identical registration of the film and at least one light sensitive sheet. An eccentric motion dial guide (20) and a linear motion drive guide (22), separately connected with drive motors (24, 26) 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 (313) by an overhead projector (311). </p> |
