Abstract: A largest page size obtaining unit obtains a largest page size of a printed matter based on manuscript data. A RIP processing unit generates a page image in a bitmap format for each page based on the manuscript data. A position determining unit determines a position within a reference page having the largest page size for each page based on the manuscript data. A display image generating unit generates a display image including a page image of a spread page by arranging the page image to be displayed at the position determined by the position determining unit. A display unit displays the generated display image. With this, there is provided an image display device which correctly displays the printed matter including pages of different sizes.

Abstract: A RIP system (100) includes a multi-screening information generator (102) for generating a multi-screening information file (Dms) which is an XML-format file containing information such as screen ruling, dot shape and screen angle, necessary for assigning a multi-screening operation, and discloses the multi-screening information file (Dms) to outside of the RIP system by storing in a shared disk or a flexible disk. On an input data creation process side, a client machine makes reference to the multi-screening information file (Dms), and thereby assign the multi-screening operation.

Abstract: A digital impositioning apparatus performs impositioning using file output of electronic data instead of film output. An impositioning portion 12 creates imposition data for each page based on arrangement information. Here, in order to conform to the type of a printer 31, the impositioning portion 12 rewrites as required the arrangement information by an instruction from a terminal 21 to create suitable imposition data. A joining portion 13 positions the above imposition data so as to be optimally arranged on a printing plate. This positioning can be performed as being checked on a screen of the terminal 21. The print information adding portion 14 reads from outside and arranges accessories required for printing. A dot generating portion 17 converts a rasterized file after the above data processing from raster style data for each page to dot data organizing a plurality of pages, in consideration of dot gain adjustment from a control peroration 15.
