Abstract: Methods and systems herein provide for verification of a calibration of a printer utilizing a hand-held mobile device. In one embodiment, a mobile device includes a camera that captures image data of a calibration target printed by a printing system. The image data is captured in an uncontrolled environment. The mobile device further includes a processor that determines a difference between the uncontrolled environment where the image data was captured and a controlled environment, and adjusts the image data based on the difference. The mobile device then determines whether the printing system is out of calibration based on the adjusted image data.

Abstract: Methods and systems herein provide for estimating when the print quality of a printer is expected to decrease below a threshold based on a function of change in the print quality of the printer. In one embodiment, a system calculates a plurality of print quality measurements based on pages printed by a printer. The system determines a function of change of the print quality of the printer that is based on changes in the print quality measurements. The system estimates when the print quality of the printer is expected to decrease below a threshold based on the function of change in the print quality of the printer. The system then provides the estimate to a print operator.

Abstract: Non integer scaling of images to reduce artifacts is presented herein. One embodiment includes determining a scaling resolution based on a pixel resolution of the image and a pixel resolution of an output device (i.e., factors of the scaling resolution). The image is converted to the scaling resolution to change (e.g., increase) the pixels of the image by the first factor. A grid is generated to scale the converted image. The grid has a number of sections defined according to the second factor times the pixel resolution of an output device. The converted image is sectioned according to the grid. Each section of the grid includes an integer number of pixels of the converted image. The color values of the pixels of the converted image are averaged within each section of the grid to compute a single color value for each section of the grid and scale the image.

Abstract: The present invention provides a method, data processing system and computer program product for providing a data stream transform service, for example for transforming a data stream into a format suitable for printing. A data-stream is divided into one or more work units, each work unit is provided to one or more transform engines to transform the work unit into the required format, and each transform engine is monitored whilst transforming a work unit. By monitoring each transform engine details of, for example, resource usage are obtained which may be used to calculate a fee to charge a client for performing transformation of a data stream, and/or failure of a transform engine can be detected and corrective action taken should a transform engine fail.

Abstract: Methods and systems herein provide for reducing artifacts during printing. One printing system is operable to prepare a continuous tone image (CTI) for printing onto a print medium by generating an initial half tone image (HTI) based on the CTI. The printing system includes a printer and a print controller. The print controller filters the initial HTI and the CTI with a perceptual filter and determines an error between the filtered CTI and the filtered HTI. The print controller prints the HTI via the printer to determine printer artifacts and processes a scanned version of the printed HTI to determine an error between the filtered CTI and the scanned and filtered HTI. This processing updates the initial HTI and reduces the error between the filtered CTI and the filtered HTI.

Abstract: Provided are a method, system, and article of manufacture for determining whether to convert image data in an input color space to an output color space in a transform domain or real domain. An input block of coefficients in an input color space is generated, wherein the input block includes a first type coefficient and a plurality of second type coefficients. The first type coefficient in the input block is converted to an output value in an output color space. A determination is made as to whether real domain processing is required. The input block is converted in a transform domain to an output block of coefficients in the transform domain in an output color space in response to determining that the output value does not require real domain processing.

Abstract: Provided are a method, system, and program for decoding compressed data. Compressed data is received and decoded. An error is detected while decoding a first location in the compressed data. A reentry data set is accessed having a pointer to a second location in the compressed data following the first location and decoding information that enables decoding to start from the second location. The second location in the compressed data is accessed and the decoding information in the accessed reentry data set is used to continue decoding the compressed data from the second location.
