First, a user who will try a service of a print system registers trial from a user system in the print system. When the trial of the print system from the user system is permitted and registered, the print system provides an RIP processing or a printing processing to a user in response to a processing request from the registered user system within a range set for the trial without charge or with a discount accounting.

Image processing system and method

An image forming control apparatus includes: a gradation correction curve generator and a calibration data generator. The gradation correction curve generator generates a gradation correction curve based on a correspondence between an output instruction values each representing a density of an image to be formed by an image forming apparatus and actual density values each representing a density of the image formed by the image forming apparatus. The gradation correction curve represents a correspondence between predetermined standard density values and the output instruction values. When an output instruction value corresponding to a maximum standard density value is smaller than a maximum output instruction value, the calibration data generator corrects the gradation correction curve so that the output instruction value corresponding to the maximum standard density value coincides with the maximum output instruction value, and generates the calibration data based on the corrected gradation correction curve.

Image forming control apparatus, image forming control method and computer readable medium

An image-formation control apparatus is connected to an image forming apparatus for forming an image on a medium with a plurality of color materials. The image-formation control apparatus includes a receiving unit and a first calibration unit. The receiving unit receives an image formation command, which is to be executed by the image forming apparatus. The first calibration unit generates a first formation command to form a first number of color patches for adjusting output characteristics of the color materials in the image forming apparatus and outputs the generated first formation command to the image forming apparatus. The first calibration unit calculates an estimated consumption amount of each color material used in the image forming apparatus on a basis of the received image formation command and determines colors of the color patches formed on a patch sheet on a basis of the estimated consumption amount.
