Abstract: A method for reassigning a section out of a plurality of sections of a digitally represented printed product from an original signature to a new signature for producing said section, the method including (i) displaying a table on a computer display, wherein the table includes a list of items, each item representing a section and including (a) a section identifier, (b) a signature identifier associated to the section identifier and representing a signature to which the section is assigned and (c) a signature portion index indicating a portion of the signature corresponding to the section; (ii) selecting on the computer display a specific item including a specific signature portion index; and (iii) moving on the computer display the specific signature portion index from one item to another one, thereby assigning a different section to a specific signature having the specific signature portion index.

Abstract: A method for defining an imposition plan for producing a first portion of a first printed product and a second portion of a second printed product, the method including (a) defining a first run list of the first portion; (b) defining a second run list of the second portion; (c) including a first page of the first run list and a second page of the second run list in a signature of the imposition plan for producing the first portion of the first printed product and the second portion of the second printed product.

Abstract: The invention relates to a method and apparatus for merging page elements according to a layout signal into one page for reproduction on a reproduction device. The page elements are segmented into smaller segments before storage into memory. Due to the particular format of the page elements, data required for the merging of page elements can be retrieved, decompressed an processed quickly so merging can be done in real time during printing. The format used for the segments enables easy and fast execution of various image operations such as mirroring, clipping, rotation, etc . . .

Abstract: The invention relates to a method and apparatus for merging page elements according to a layout signal into one page for reproduction on a reproduction device. The page elements are segmented into smaller area tiles before storage stored into memory. Data from the page elements includes metadata describing the position into the memory of the sub-elements of the page element. Due to the used format for the page elements, data needed during merging can be retrieved, decompressed an processed quickly so merging can be done in real time during printing. The format used for the area tiles enables easy and fast execution of various image operations such as mirroring, rotation, etc . . . Complexity data can be incorporated into the page element data, giving information about the amount of processing required to execute the merging.

Abstract: A method is disclosed for producing a colour image by printing on a sheet a plurality of monochrome images on top of each other. The monochrome image (37) is composed of microdots (36), having an address (x,y). Each microdot (36) is represented by a pixel (32). The pixel (32) carries information about the address (x,y) and an image signal .sup.I x,y that corresponds with the density to be printed on the microdot (36). This image signal is given as 8 bit signal data for example. The microdots (36) are partitioned by a screen (40) in identical screen cells (33), composed of M microdots (36). Each microdot is associated with a pixeltonecurve (34). The image signal .sup.I x,y is transformed to a bitmap signal B by the pixeltonecurve (34). The image signal .sup.I x,y is transformed to a bitmap signal B by the pixeltonecurve (34) corresponding to the microdot (36). The bitmap signal B is represented by 2 or 4 bit resulting in important memory savings for the bitmap signals.
