An image forming system includes an image forming apparatus and a server. The image forming apparatus transmits to the server image data representing an image. The image is read by the reading device from the recording medium on which the print device prints the image, in response to an instruction to print at the origin of the print area. The server acquires, from the image data transmitted from the image forming apparatus, a printing-complete reference position, as a position where the recording-medium origin is made a reference, in a location printed on the recording medium by the image forming apparatus in response to an instruction to execute printing at the print-area origin, and acquires the displacement as a difference between the acquired printing-complete reference position and the print reference position stored in the storage device.

An image processing system for sequentially executing processes includes a process execution control apparatus to control an execution of the processes, and an image generation-output control apparatus to control an execution of image generation-output operation. The process execution control apparatus includes a control-side drawing information generator to generate drawing information to be referred when an image forming apparatus performs the image generation-output operation. The image generation-output control apparatus includes an output-side drawing information generator corresponding to the control-side drawing information generator. The control-side drawing information generator excludes an execution result of a designated process item from execution results of a plurality of process items, to be executed for generating the drawing information, to generate designated-information-excluded image information. When process contents of the designated process item is set at the image generation-output control apparatus, the output-side drawing information generator executes the plurality of process items based on the designated-information-excluded image information.

A raster image processor (RIP) system is used in a printing system to process a variety of different jobs. A front end receives the jobs and determines the job type. The job types include a print job, a preview job, and an estimation job. Depending on the type of job, the front end configures the RIPs within RIP system accordingly to process the job. The RIPs may process the job in parallel, with a high performance RIP processing the first page of the job. If the job is not processed in parallel, then the front end assigns the job to a very high performance RIP. The front end also assigns the preview job to a preview RIP and the estimation job to an estimation RIP. The front end configures RIPs as needed.

In a case where another first region exists which faces the edge pixel across a second region on a line in a predetermined direction passing through the edge pixel of the first region, the correcting unit selects a correction amount for correcting the exposure amount applied by the exposing unit for the pixel to be corrected from information describing a plurality of correction amounts in accordance with a first number of pixels being a number of pixels on the line within the second region between the first region and the other first region and corrects the exposure amount for the pixel to be corrected in accordance with the selected correction amount.

An image processing apparatus includes a memory to store instructions, and one or more processors to execute the instructions and cause the image processing apparatus to function as a count unit and a determination unit. The count unit counts an image object of gray in an input image as a color pixel, wherein the count unit does not count an image object of white in the input image as a color pixel. The determination unit determines whether the input image is a color document based on a number of color pixels counted by the count unit.

An image processing system includes a process execution control apparatus to control an execution of processes, and an image generation-output control apparatus to control an execution of an image generation-output operation. The process execution control apparatus includes a control-side drawing information generator to generate drawing information, and a process allocator to allocate a plurality of text information adding processes to the process execution control apparatus and the image generation-output control apparatus when generating the drawing information. The image generation-output control apparatus includes an output-side drawing information generator corresponding to the control-side drawing information generator.

An image forming apparatus includes: a first correction unit configured to obtain a measurement value of a correction amount based on a detection result by a detection unit, and correct an image forming condition based on the measurement value; a second correction unit configured to obtain a variation value by a prediction calculation at a predetermined timing, obtain a prediction value by accumulating the variation value since the first correction unit performed the correction, and correct the image forming condition based on the prediction value, the variation value being a estimated value of the correction amount; and a determination unit configured to obtain an evaluation value related to a prediction error based on the variation value since the first correction unit performed the correction, and determine, based on the evaluation value, the correction timing by the first correction unit.

A display processing apparatus includes a gloss-control plane generating unit configured to generate gloss-control plane data for specifying a type of a surface effect applied to a recording medium and an area in a recording medium to which the surface effect is applied; an obtaining unit configured to obtain replacement information that is used to replace a type of the surface effect that is not available in a device configuration with a type of the surface effect that is available in the device configuration; a replacing unit configured to replace the type of the surface effect designated by the designation information with the type of the available surface effect using the replacement information obtained by the obtaining unit; and a preview image generating unit configured to generate a preview image based on the gloss-control plane data having an area to which the available surface effect is to be applied.

When time required for print processing is estimated, estimation in consideration of overlap between objects is performed in such a manner that the objects are regarded as objects with a predetermined simple shape.

A visual display assembly adapted for use as an anti-counterfeiting device on paper currency, product labels, and other objects. The assembly includes a film of transparent material including a first surface including an array of lenses and a second surface opposite the first surface. The assembly also includes a printed image proximate to the second surface. The printed image includes pixels of frames of one or more images interlaced relative to two orthogonal axes. The lenses of the array are nested in a plurality of parallel rows, and adjacent ones of the lenses in columns of the array are aligned to be in a single one of the rows with no offset of lenses in adjacent columns/rows. The lenses may be round-based lenses or are square-based lenses, and the lenses may be provided at 200 lenses per inch (LPI) or a higher LPI in both directions.
