A system and a method for driving an output device in which both product intent and production details are entered by a print producer on a submission portal. When a product definition is complete, the job is transferred to a prepress server where it is rendered which involves pre-flighting the job. In a next step, rendered color separations together with output device specific instructions are sent to a print server from where the job is printed.

System and method for driving an output device

An apparatus and a method are disclosed for digitizing a color negative picture and correcting the image signals in a way that they are linearly related to the luminance of the photographed scene for grey tones in the scene. A second embodiment allows obtaining on the basis of the color-corrected image signals a reproduction of true color of the scene on a color display unit. For determining the correction, use is made of the characteristic system curve indicating for each of the color components the relation between the luminance of a neutral color swatch in the scene and the density sensed by the scan system. Several methods for drafting said system curve are described. Furthermore, the way of obtaining the color-corrected image signals by means of a color transformation and the way of determining the transformation are explained.

Color negative scanning and transforming into colors of original scene

A method and apparatus is provided for scanning original images wherein the original images are scanned by a scanner and processed in a computer workstation. The scanning of an original image is carried out simultaneously with the processing of at least one other original image. A method and apparatus for scanning an original image wherein the original image is scanned in bands by a scanner and processed in a computer workstation. The scanning of one band is carried out simultaneously with the processing of at least one other band.

Color negative scanning and transforming into colors of original

A method is described for selective color correction of an original color image. In one embodiment, a color is selected by picking a colored pixel from the color image and a changed color, having a restricted color change, is associated with the selected color. All original colors, situated within a local color gamut, comprising the selected color, undergo a color modification according to the color change. The effect of the modification decreases as the original color reaches the boundary of the local color gamut. The selected color and changed color may be defined in the native color space, the local color gamut is preferentially defined by an action radius related to a psychometric color space. Two or more selective color corrections may be combined by a weighted mean modification, by choosing for each color change a weight value, which decreases as the selected color is more different from the original color.
