  • Publication number: 20100218257
    Abstract: A program obfuscation method includes: detecting a loop from an obfuscation target program; adding a conditional expression to the obfuscation target program at a preceding stage of the loop, wherein the conditional expression is neither permanently invalid nor permanently valid and adding a flow in which (a) when a logical value of the conditional expression is false, processing of the obfuscation target program proceeds to a start of the loop, and (b) when the logical value of the conditional expression is true, the processing executes a set of executable statements equivalent to a set of executable statements which are ones from the first executable statement to a middle executable statement among a plurality of executable statements in the loop, and then the processing proceeds to an executable statement subsequent to the middle executable statement in the loop.

  • Publication number: 20100215262
    Abstract: What is disclosed is a novel system and method for performing ray-based compression mapping in a color management system. The present method compresses a color point located at or near a boundary surface of a color gamut to a point beneath the gamut surface in order to eliminate artifacts which are likely to arise from a color marking device trying to reproduce colors which are on a boundary of the device's printable gamut. The present method is directly applicable to a variety of gamut mapping strategies employed in color management systems.

  • Publication number: 20100215865
    Abstract: A method of forming a printing master on a flexographic plate by melting a radiation-curable phase change ink including at least one curable monomer, at least one phase change agent, at least one photoinitiator and an optional colorant. Multiple layers of the melted phase change ink are then deposited on the flexographic plate to form a raised pattern. Each of the deposited layers of ink are gelled before the deposition of a subsequent layer on the deposited layer. After a printing master with sufficient thickness is formed on the flexographic plate, the ink on the flexographic plate is cured.

  • Publication number: 20100215382
    Abstract: The present invention provides an image forming device including: plural image formation sections, a second exposure section, a transfer body, a reading section and an identification section. Each image formation section includes a control section that controls a first exposure section to form an identification image of a color represented by color information in accordance with an image formation instruction. The second exposure section performs exposure onto a charged image-bearing body and forms an electrostatic latent image. An image is formed at the transfer body. The reading section reads an image. The identification section outputs to the plurality of image formation sections an image formation instruction and, on the basis of a duration from the output until the identification image is read by the reading section, identifies a position of the image formation section forming the image of the color instructed by the image formation instruction.

  • Publication number: 20100214598
    Abstract: A computer implemented system and interactive method for selecting finishing options for a print job are disclosed. The method includes receiving a print job which includes a document to be printed and associated job ticket information. Printers capable of executing the print job are identified and a user selection of one of the capable printers is received. Finishing options available on the selected printer are displayed and a user-selected one or more of the displayed finishing options are received. A three-dimensional visualization of the document as it would be rendered on the user-selected printer with a user selected finishing option(s) is generated.

  • Publication number: 20100215385
    Abstract: An image forming device includes an image holding member and a charging unit. In a case in which an AC current, while being increased, is supplied to the charging unit in a state in which a DC voltage value and an AC voltage value applied to the charging unit are maintained, or a case in which a DC voltage, while being increased, is supplied to the charging unit in a state in which the AC voltage value applied to the charging unit is maintained, a current detection unit detects DC current values. An inflection point derivation unit derives an inflection point of a correlation line representing an correlation between the detected DC current values and the supply amounts. An execution unit executes pre-specified processing when a characteristic value of the derived inflection point reaches a pre-specified value.
