Abstract: In a method for copying originals onto photographic single-sheet copy material, the original is scanned, and on the basis of the scanning values obtained the requisite quantities of copying light for the ensuing copying of the original onto the single-sheet copy material are ascertained. First, the unexposed single-sheet copy material is transported into the exposure beam path, then acted upon by the quantities of copying light ascertained previously, and finally removed for further processing. During the removal of the exposed single-sheet copy material, the next piece of unexposed single-sheet copy material is being transported into the exposure beam path.

Abstract: Individual sheets of a sheet material to be treated which arrive in an arrival sequence, are distributed on two or more adjacently located conveying tracks. The sheets are conveyed along the conveying tracks through a processing station and are sorted thereafter in accordance with their arrival sequence. The distribution of the sheets is based on evaluating utilization of the conveying tracks to minimize the distance between sheets following each other on the same transport track. A throughput for sheets with varying length that is approximately equal to the throughput for sheets of same length is achieved.

Abstract: An improved method and apparatus to record picture information on recording material in the form of single sheets. The picture information to be recorded for each sheet is present in electronically stored pixel form and is recorded pixel by pixel onto the recording material. The sheets of the recording material are transported through a paper stage of a printer in at least two adjacent tracks, and the stored picture information belonging to the respective sheets located in the recording station is recorded onto the sheets located in the adjacent tracks. Because the sheets are transported in a plurality of tracks through the recording station, a higher throughput can be attained even if smaller sheet sizes are being processed.

Abstract: In a method for producing photographic copies, first copies are produced in a first pass in a first printer, and any second copies needed are produced in a second pass by a second printer which is calibrated to the first printer by means of a setup test method. In this setup test method, the original-specific data ascertained in the first pass are delivered to a computing and control unit of the second printer. With the aid of these original-specific data and with the aid of an original model adapted to the copying material, the requisite quantities of copying light are ascertained in the computing and control unit of the second printer, and the second copies are made. The developed second copies are subjected to an analysis. Based on the analysis, the original model adapted to the copy material is optimized for the second printer until the second copies are substantially identical to the first copies.

Abstract: A method for producing copies of photographic originals, wherein an original is scanned regionally. With the aid of measurement data thus obtained, a decision is made in a test step, on the basis of specified criteria, whether the original is worth copying or not. On the basis of this decision, the particular original is or is not copied onto photographic copy material. In the test step, the scanned original is assigned to at least one of at least three categories of originals; namely a first category which includes originals that are unequivocally worth copying, a second category which includes originals that are unequivocally not worth copying, or a third category which includes originals that are neither unequivocally worth copying nor unequivocally not worth copying.

Abstract: Process for preparing film strips for subsequent orders, the film strips belonging to a customer order. Each film strip includes a number of numbered masters which are fed into a preparation station. There, they are glued to a carrier belt and coiled into a film roll, which can be used at subsequent processing stations. Customer-specific order data regarding the desired number of copies of specific masters and, where applicable, the desired copy format, are entered via an input unit in the preparation station and stored onto a carrier medium which is compatible with the subsequent processing stations. In the process, the customer-specific order data are entered before the film strips are fed in.

Abstract: During the processing of an order in a photographic printer, a developed copy film strip can be scanned negative by negative and point-by-point in a scanning station of the printer. From the scan signals, density values for exposure time determination in three partial colors and details on the image field number of the scanned negative can be obtained, and these data are stored in a memory, coordinating the determined three partial exposure times with the corresponding image number. All negatives of the copy film strip are exposed successively on photographic paper on an enlarged scale, using the determined exposure times. In a further step, a number of successive negatives of the film strip are exposed on full-scale or reduced scale in matrix form onto a single sheet of said photographic paper.

The second exposure arrangement includes a cathode ray tube with control system. The cathode ray tube is arranged at approximately a right angle with respect to the exposure light path of the first exposure arrangement. The second exposure arrangement further comprises a color filter assembly, an objective and a mirror for directing the screen copy master emitted by the cathode ray tube to the photographic copy material. The color filter assembly, the objective and the mirror are combined as a structural unit to constitute an imaging optical system, which can be positioned into the exposure light path instead of an reproduction objective of the first exposure arrangement.

Abstract: A device for copying photographic masters onto photographic copy material, the device including a masters stage on which the master is conveyed to a measuring station where it is impacted with light and measured. Subsequently, copying light quantities required for exposure are determined from this measurement. After the measuring station, in the direction of conveyance, there is an exposure station, where the master is impacted with the determined copying light quantities and copied onto copy material. The device further includes a transmission measuring system and a reflection measuring system for measuring test masters or test copies. The transmission measuring system and the reflection measuring system are integrated, structurally speaking, in an area of the masters stage on which the master is conveyed, measured and copied onto the copy material.
