Abstract: An image forming system includes: a resource information storage unit that previously stores resource information to be combined with input print information; a first setting unit that sets an image characteristic of the resource information stored in the resource information storage unit; a second setting unit that sets an image characteristic of the input print information; and a color conversion unit that, when the image characteristic set by the first setting unit and the image characteristic set by the second setting unit are different, performs color conversion on the resource information based on the image characteristic set by the first setting unit, and performs color conversion on the print information based on the image characteristic set by the second setting unit.

Abstract: Since many ICC profile generation tools print and measure a large number of color patches and then make profile generation calculations, profile re-generation requires a long time. Hence, patch data are generated, calorimetric values corresponding to the patch data are obtained. Reference values of an Lab color space, which correspond to the patch data, are calculated using a conversion lookup table from a CMYK color space to the Lab color space, which is included in a profile. A conversion lookup table from the Lab color space to the CMYK color space, which is included in the profile, is updated using the calorimetric values and reference values.

Abstract: A recording apparatus having a buffer to store recording data associated with a recording area in a scanning direction of a recording head divided into a plurality of areas. The buffer stores the recording data in units of the divided areas. The recording apparatus includes a signal generation unit configured to output a signal according to a position of the recording head, a transfer data generation unit configured to generate transfer data transferred to the recording head based on the signal output from the signal generation unit, and a pattern data generation unit configured to generate predetermined pattern data. The transfer data generation unit includes a first input section for receiving the recording data read from the buffer and a second input section for receiving the pattern data generated by the pattern data generation unit.

Abstract: A method and graphical user interface for selecting pad printing functions for an image output device. The user interface is provided to a user and displays a pad printing dialog box that enables selection of pad printing output. Selectable pad printing options are displayed, which include the number of sheets per pad and the total number of pads to be output. When the user selection of pad printing and pad printing options are received, the total quantity of sheets to be output based on selected pad printing options and organizing the sheets for pad printing output from the image output device are automatically determined. Availability of pad printing is determined based on finishing options selected.

Abstract: A pattern producing unit performs arithmetic on values of pixels corresponding to a pattern and a basic pattern read from a data storing unit with an AND operation unit, and thereby produces a pattern having substantially the same shade level as the pattern. The latent-image-containing image producing unit produces the latent-image-containing image by selectively combining the pattern and the produced pattern according to the values of respective pixels of mask image data read from the data storing unit for producing a latent image.

Abstract: A document reader comprises line sensors that are staggeredly arranged and read a white reference plate to obtain a white reference read value A, and a white reference average value AA is determined from value A for each line sensor. The line sensors read another white reference plate placed on a document support plate to obtain a white reference read value B, and a white reference read average value BB is determined from value B for each line sensor. A sensitivity effect coefficient C for each line sensor is determined by dividing BB by AA. Using the line sensors, there are obtained a document read value E for each line sensor by reading an illuminated document on the document support plate, a white reference read value Aa by reading with the white reference plate before reading the document, and a black reference read value D by reading the white reference plate under a condition that an illumination is turned off before reading of the document.

Abstract: A method for configuring a printer to automatically print multiple proof prints includes configuring a printer with an adjustable process parameter to a first value, configuring the adjustable process parameter to a second value; generating a single submission event that expresses the first value and the second value of the adjustable process parameter, and configuring the printer with the single submission event such that the printer automatically prints a first proof print with the first value and a second proof print with the second value.

Abstract: Disclosed is a print controlling device including a control unit to control printing according to an instruction which relates to the printing, wherein the control unit analyzes a page description language which relates to the printing, determines whether the printing is practically monochrome printing or color printing, and changes a first command of the page description language to a second command for monochrome printing when it is determined that the printing is monochrome printing.

Abstract: An image generating method comprises the steps of extracting elliptical shape parameters (specifying an elliptical shape), gradation pattern parameters (specifying a gradation pattern to be drawn in the elliptical shape) and drawing area parameters (specifying a drawing area) from an instruction for drawing an elliptical radial gradation, generating a transformation matrix for transforming the elliptical shape into a perfect circular shape based on the elliptical shape parameters, calculating an inverse matrix of the transformation matrix, transforming the gradation pattern parameters using the transformation matrix, transforming a first area containing the drawing area using the transformation matrix, drawing a radial gradation in the perfect circular shape in a second area containing the transformed first area based on the transformed gradation pattern parameters, and generating the elliptical radial gradation for the drawing area by inversely transforming the second area (in which the radial gradation has

Abstract: An original size detecting apparatus is capable of carrying out accurate original size detection without erroneous detection of the size of an original due to the influence of external scattered light. A CCD reads reflected light of light irradiated from a light source onto an original placed on an original platen glass. Optical sensors detect two open states of the original presser plate, and a scanner controller performs predetermined control corresponding to each of the open states of the original presser plate detected by the optical sensors, to determine the size of the original based on the result of the reading by the CCD.
