摘要： A photographic copier has a first platform for supporting an original to be copied, and a second platform for supporting copy paper. A focusing system is disposed between the platforms and includes a plate which can be mounted at different distances from the platforms. The plate has a central opening which removably receives a tubular holder. The holder is supported in the opening by a ring which permits the position of the holder relative to the plate to be adjusted. Two lenses are removably mounted in the holder and serve to project an image of the original onto the copy paper. Different magnifications can be achieved in that the copier comes equipped with a variety of holders having different lengths, and a few selected lenses having different optical characteristics. The magnification is changed by simply interchanging holders and/or lenses, and adjusting the position of a holder to be used relative to the plate.

摘要： A copier has a movable housing which accommodates a support for an original to be copied, a source of illumination for the original, a lens system for forming an image of the original and a support for photosensitive material which is to receive the image. The housing has an opening in one of its sides and carries a hinged lid for lighttight sealing of the opening. A reflector is pivotally mounted inside the housing in the vicinity of the opening and can be moved between an operative position in which it intercepts the image from the lens system and an inoperative position in which it does not. When an image of normal size is required, the reflector is in its inoperative position and the image is projected onto the photosensitive material located inside the housing. When an image of large size is required, the reflector is brought into its operative position and the opening in the housing is uncovered. The reflector can then project the image through the opening and onto a large sheet of photosensitive material held on a wall or other suitable support.

摘要： An exposed and developed filmstrip and band of similar length are connected edge-to-edge. An address for each negative of the filmstrip is imprinted on the band in the form of a bar code adjacent to the respective negative. The negatives are scanned and exposure values are calculated for the negatives from the resulting data. The exposure values are used to make proofs, and the exposure values for each negative are then stored in a memory under the corresponding address. When an order for final copies of a particular negative is subsequently received, the address of the negative is read from the band and used to retrieve the respective exposure values from the memory. The final copies are thereupon made based upon the retrieved exposure values.

摘要： A film has a series of exposed and developed negatives. Each negative is scanned at a multiplicity of regions, and the densities of each region in the three primary colors are measured. A blue/red density differential is derived for each region by subtracting the red density of a respective region from its blue density. The neutral density of each region is calculated, and every region is assigned a coordinate on a plot of blue/red density differential versus neutral density. According to one embodiment, the blue/red density differential for each region having a neutral density equal to or greater than a limiting value is then subtracted from the blue/red density differential given by a characteristic curve for the film. The differences obtained in this manner are analyzed, at least for selected negatives, and the minimum difference for each selected negative is determined. The region corresponding to the minimum difference is that region of a negative having the maximum blue density. The blue/red density differential for the region of maximum blue density is compared with a pair of reference values derived from respective reference curves representing blue/red density differential as a function of neutral density. Based on the results of this comparison, each selected negative is classified as to whether it was exposed by artificial light or natural light, and is assigned an appropriate color correction factor for copying. Another embodiment is employed if the characteristic curve is found to lie near one of the reference curves. Here, the steps of subtracting blue/red density differentials and analyzing the resulting differences are omitted, and all negatives of the film are immediately classified as having been exposed by artificial light.

摘要： A lengthy strip of originals is transported along a transport path. Positioned along the transport path are a plurality of copying stations, for simultaneous copying of plural successive originals. The originals are transported setwise or batchwise, thereby lowering the average transport time per individual original and increasing copying-machine productivity without the need to speed up the performance of other operations attendant to copying-machine operation. When originals are correctly spaced and all copiable, they are processed setwise or batchwise as just outlined. When not spaced in accordance with a standard and/or when not all copiable, the machine changes over to one-at-a time operation, disabling all but the most downstream copying station, until the arriving originals are again all copiable and spaced by the standard distance. During normal operation, a strip of print paper is advanced by an increment corresponding to the plural concurrently exposed originals. During one-at-a-time copying, the strip of print paper is advanced one print at a time, and the strip of originals is advanced until the next copiable original arrives at the most downstream station.

摘要： Color prints from transparencies which constitute frames or sections of universal film are made on printing paper by ascertaining the quotient or difference of integrated transmittance of the transparencies in green and red light, comparing the signal which denotes such ratio with a variable reference signal whereby the resulting comparison signal denotes the color temperature of light by which the respective transparency was exposed, and carrying out color corrections to depart from correction to neutral gray in dependency upon whether the ascertained color temperature denotes exposure in daylight or artificial light. The value of the reference signal is changed in such a way that the intensity of the ratio-designating signal which is necessary for generation of a comparison signal denoting the switchover point between the classification of transparencies into those respectively exposed by daylight and artificial light is lowered when the overall density of the transparency is lower and vice versa.

摘要： A color copying apparatus having a photoelectric color exposure control device is calibrated by making a copy of a calibrating original, which includes a gray stepped wedge, on a photographic copying material using an exposure determined by the photoelectric color exposure control device and assumed to be proper for achieving the desired density values in the developed image of the calibrating original. The density of the developed image of the gray stepped wedge is then measured in order to obtain actual density values, which are compared with corresponding desired density values. Finally, the photoelectric color exposure control device is adjusted for achieving the required exposure correction as determined during the comparison of the actual and desired values. The calibration is performed for each of the individual values so that correction of the control device is also achieved for each of the corresponding colors.

摘要： Successive frames of a web of photographic color film are subjected to objective examination during transport through an automatic evaluating circuit which may constitute a discrete prereader or a prereader which is integrated into a copying machine upstream of the copying station. The prereader furnishes signals which represent color and/or density correction data for reproduction of those film frames which can be properly copied only with a setting of exposure controls which deviates from the average setting for copying of the majority of film frames. The objective examination of all film frames is followed by a subjective examination which is performed by an attendant who inspects at least some of those film frames whose examination by the prereader resulted in the generation of correction signals. The attendant inspects the film frames at the copying station or at a second station which is located immediately downstream of a discrete prereader, and the attendant simultaneously observes the corresponding correction signals which are furnished by the evaluating circuit and are displayed close to the copying station or in register with film frames at the second station. The attendant can approve, modify or cancel the correction signals, and can also initiate the generation of additional signals, e.g., to identify those film frames which are unfit for copying.

摘要： An automatic prereader for exposed and developed frames of a web of spliced-together photographic color films is preceded by a first station and followed by a second station at the first of which groups of successive frames are subjected to a first subjective examination by an attendant and at the second of which some of the frames are subjected to renewed subjective examination by the same attendant. The attendant actuates one or more pushbuttons upon examination of frames at the first station to produce signals which denote improperly oriented frames, frames which were exposed in artificial light and/or frames which are unfit for copying. Such signals are used to modify signals which are furnished by the automatic prereader. The modified and unmodified signals which are furnished by the prereader are examined for intensity, and those signals whose intensity is outside of a preselected range are displayed at the second station so that the attendant can observe such signals simultaneously with observation of the respective film frames and is in a position to initiate the generation of additional signals which are used to modify or erase the corresponding signals from the prereader before the signals are transmitted to the exposure controls of a copying machine.
