  • Patent number: 6335147
    Abstract: There is disclosed a developing processing method and apparatus in which developing processing is carried out with a developing solution being jetted toward an emulsion surface of a photosensitive material from jetting holes of a blowoff chamber. Only one blowoff chamber is disposed in a developing tank and conveying roller sets are disposed at both sides of the blowoff chamber. The photosensitive material is horizontally conveyed above the blowoff chamber by the conveying roller sets. Due to the number of components of the developing processing tank being thus reduced, the apparatus can be made small in size. Positions where the photosensitive material is nipped by the roller sets are located within a processing solution, and therefore, there is no possibility of the photosensitive material being nipped and conveyed in a state in which outer peripheral surfaces of the rollers are wet non-uniformly with the processing solution. As a result, non-uniform processing is prevented.

In this case, clogging of the jetting holes does not easily occur and the processing solution can be jetted from the jetting holes stably for a long period of time. Accordingly, non-uniform processing is rarely caused. Intervals between the jetting holes in the transverse direction of the photosensitive material are each in a range of 3.0 mm to 4.5 mm. The jetting holes are disposed in such a manner that jetting holes of adjacent three rows in a direction in which the photosensitive material is conveyed are located at different positions to form a staggered arrangement, and the three rows of jetting holes are formed repeatedly.

  • Patent number: 5851243
    Abstract: A radiographic element is disclosed capable of producing a maximum density of at least 3.0 when imagewise exposed and processed in less than 45 seconds. The element includes magenta dye or dyes, including a dye for spectrally sensitizing radiation-sensitive silver halide grains, that leave a residual density at 505 nm of greater than 0.1 when the element is processed. Transmission of red light through the radiographic element when imagewise exposed and processed to produce a viewable image is reduced by the incorporation in at least one of the hydrophilic colloid layers of at least one ionic linear condensation polymer containing a cyan phthalocyanine dye.

  • Patent number: 5840470
    Abstract: Silver bromide color negative films can be rapidly processed using shortened color development times and specific amounts of color developing agent and bromide ion. After development, and optionally desilvering or fixing, the developed film is scanned to form density representative digital signals for the color records. These signals are then digitally manipulated to correct both interimage interactions and gamma mismatches around the color records to produce a digital record that is capable of providing a display image having desired aim color and tone scale reproduction. That digital record can then be stored or used to provide corrected display images, such as color prints, using output display devices.
