Abstract: A method for selecting a colorant amount for printing is described in which a maximum optical density of an image is identified. The maximum optical density is compared to with a threshold optical density, and when the threshold is exceeded, dot cluster sizes from a first lookup table are selected, otherwise, dot cluster sizes from a second lookup table are selected. A colorant thickness corresponding to the selected dot cluster sizes is selected for printing the image.

Abstract: A film exposure apparatus employs a liquid crystal display. The film exposure apparatus may reduce the film and plate fabrication cost and time required in a publication printing process and may also enhance printing quality. The apparatus may include an exposure device that illuminates the LCD. The LCD may display an image in one or more gray scales that may correspond to color concentrations in a document to be reproduced. The LCD may control the amount of light that passes through the LCD and that exposes red (R), green (G), and blue (B) films.

Abstract: A method for the automatic reproduction of the colors of an original scene from an original image present as a color negative or diapositive film includes scanning the original image electronically, and storing the RGB color values of the image points as scanned transmissions or scanned densities. In the RGB color space, a gray straight line is determined, which approximates the cloud of points formed by the scanned densities of the image points in an optimum way. The transmissions are corrected by minimum transmission values in each case being subtracted from the scanned transmissions. Then, reconstructed film exposures are determined, whereby, by the gray straight line, film exposure straight lines are constructed that describe the relationship between the logarithmic film exposures and the corrected densities. Following the normalization of the film exposures to a standard image range, the film exposures are transformed into the LAB color space.

Abstract: A method of and apparatus for printing color images by the superimposition of a number of separations, using a first half-tone technique optimized for surface reproduction, such as dithering, and a second half-tone technique, differing from the first and optimized for edge reproduction, such as thresholding with error diffusion, is disclosed. The second half-tone technique is used in edge transitions for pixels of a separation which substantially influences the edge transition, and the first half-tone technique is used outside the edge transition. And the first half-tone technique is used throughout in the case of pixels of a separation which provide no or minimal contribution to the edge transition.

Abstract: Disclosed is a full color printer which comprises a optical writing head for writing a latent image onto a printing paper such as a silver salt-sensitive member. The optical writing head has an array of optical shutter elements each of which is made of PLZT. Red color light, green color light, and blue color light are sequentially projected to the light shutter element, and the drive voltage applied to the light shutter elements is changed synchronized with the color change. To prevent the generation of spike noise, the drive voltage is not changed suddenly, but is changed smoothly.

Abstract: A method and an apparatus for printing images on different mediums, such as images recorded on a photographic film and index print images onto photographic paper while an image printing device is reduced in size. A film carrier is positioned to a first position so that images recorded on a negative film set on the film carrier are exposed by a light source. Further, the film carrier is moved to a second position so that images formed on a liquid crystal panel are exposed by the same light source as that used for the exposure of the images on the negative film.
