Abstract: An image processing device (140), which converts multivalued pixel values of an RGB color space corresponding to original colors of a multicolor original image into multivalued pixel values of a CMY color space corresponding to color inks used for printing in order to overprint a multicolor original with a plurality of color inks, includes: a color space coordinate conversion unit (141) configured to convert the multivalued pixel values of the RGB color space into the multivalued pixel values of the CMY color space corresponding to the color inks used for printing with reference to a color conversion LUT (131) for storing relationship between the multivalued pixel values of the RGB color space and the multivalued pixel values of the CMY color space; and a correction unit (142) configured to correct the multivalued pixel values of the CMY color space converted with reference to the color conversion LUT in response to the color inks used for printing and an overprint sequence thereof.

Abstract: One of printers linked with each other by way of a network is selected according to a printing condition for a given printing job. System information on whether the selected printer makes print in a plate printing system or in a non-plate printing system is obtained. The given printing job is output to the selected printer so that the selected printer makes copies by page when the selected printer makes print in a plate printing system.

Abstract: A Loran receiving apparatus is repeatedly switched by the actuation of a display mode changeover means between the state of displaying a plurality of measured time differences on a display in a sequential order and the state of continuously displaying only one of the measured time differences. A Loran signal detector detects a phase code of an incoming Loran signal. The detected phase code is stored in N memory parts, each corresponding to the Loran signal repetition period. Coincidence of the outputs from the memory parts is detected as the presence of a correct Loran signal.
