Abstract
A latensifier for developing latent images recorded on direct print paper includes a pair of generally U-shaped fluorescent lamps mounted to expose the paper to latensifying radiations, the planes of said lamps being disposed at a right angle to each other, with a neutral density step filter arranged in association with one of the lamps to control pre-conditioning radiation to the paper, reflectors operatively associated with the second of the lamps to control additional pre-conditioning radiation to the paper and also to allow maximum use of the second lamp for recorded image development, the second lamp being selectively energized in accordance with the speed of relative movement of the lamps and paper.
Claims6
Apparatus for latensifying images which have been recorded on direct print media comprising first and second sources of latensifying radiation, said first source being operable to expose a first transverse portion of said direct print media at a first linear position thereof, and means associated with said second source and selectively operable in an on/off mode to expose other transverse portions of said direct print media at different positions linearly displaced with respect to said first transverse portion and simultaneously with the exposure of said first portions by said first source.
Apparatus for latensifying images which have been recorded on direct print media comprising first and second sources of latensifying radiation, said first source being operable to expose first portions of said direct print media at a first linear position thereof, and means associated with said second source and selectively operable to expose other portions of said direct print media at different linear positions thereof and simultaneously with the exposure of said first portions thereof by said first source, said recording media being movable relative to said sources of latensifying radiation and including further means associated with said second source to direct said radiation to said other portions of said direct print media wherein, with respect to said direction of movement of said media, a first part of said other portions of said media is positionally ahead of said first portions and a second part of said other portions is positionally after said first portions.
Apparatus for latensifying images which have been recorded on direct print media comprising first means to expose said direct print media to latensifying radiations, said recording media being linearly movable at a first and a second range of speeds relative to said first means, and second means associated with said first means and selectively operable in accordance with the range of speeds of said relative movement to vary the energy level of latensifying radiations to which said recording media is exposed.
Apparatus for latensifying images which have been recorded on direct print media comprising first and second sources of latensifying radiation to which said direct print media is adapted to be exposed, said direct print media and said first and second sources being relatively movable and means selectively to energize at least one of said sources in accordance with the speed of said relative movement, whereby to vary the energy of the latensifying radiation to which said direct print media is exposed in accordance with the exposure time of said direct print media to said sources, and further means for directing latensifying radiations to said direct print media prior to and subsequent to the exposure portion of said direct print media to said first-mentioned source of latensifying radiation.
