Examples are described herein for imposing print jobs across lane(s) of a print medium web for frame-by-frame printing. A frame rewind distance (FRD) may be set to a length of a longest pattern of the print jobs and a frame repeat length (FRL) may be set to a difference between a frame length and the FRD. For each lane of a first frame of the frame-by-frame printing: patterns of one of the print jobs may be imposed along a length of the lane, and a distance that a tail end of the one of the patterns extends beyond the FRL may be preserved as a respective gap length for the lane in a second frame. For each lane of the second frame of the frame-by-frame printing, patterns of one of the print jobs may be imposed beginning at the respective preserved gap length.

In an example, a method includes rasterizing a seed image using a processor. A plurality of rasterized modified images may be generated from the rasterized seed image. Generating each rasterized modified image may include determining an image attribute modification and applying the determined image attribute modification to at least a portion of the rasterized seed image to generate the rasterized modified image.

Generating rasterized modified images from a rasterized seed image

Multiple packages are manufactured by defining a package template, with at least one individualized image area, and selecting at least one image seed. For each package, an index key is selected and, based on the selected index key, a plurality of image attribute modifications are determined from within applicable ranges of image attribute modifications. The determined image attribute modifications are applied to the image seed or seeds to generate respective images, and the image or images are applied to the respective individualized image area of the package.

Generation of images

An example method is provided in accordance with the present disclosure, which may be used for example for aggregating print jobs on a web of print medium for frame by frame printing. The example method comprises imposing several print jobs, each comprising patterns to be printed, on the web of print medium, in at least two parallel lanes in the longitudinal direction of the web of print medium, wherein the patterns imposed in each frame are whole patterns, a starting point for the imposition of patterns in each lane and each frame depends on an end point of the imposed patterns in the same lane in the previous frame, and a frame rewind distance is determined for each frame whereby, when printing on the web of print medium, the starting point of each lane in one frame comes to be adjacent to the end point of the lane in the previous frame.

Methods and devices for a lenticular image product include a print media, a printed faceted surface disposed on the print media, an interlaced image printed on the printed faceted surface, and a printed lenticular lens printed on the printed interlaced image and the printed faceted surface. The lenticular lens can be disposed over the print media selectively.

Printed facets

A VDP workflow system and method are disclosed. The system includes an image memory to store a photograph image. The system also includes a VDP document tool to access the photograph image from the image memory and to generate a VDP document comprising the photograph image. The system further includes a red-eye removal tool to process the VDP document to discover red-eye artifacts and to remove the red-eye artifacts from the photograph image on the VDP document based on a programmable red-eye sensitivity value.

Red-eye removal systems and method for variable data printing (VDP) workflows

Automated imposition wherein a print job comprises multiple documents, and the documents comprise pages having different dimensions. Pages of different dimensions of the same document may be imposed on a single sheet, and pages of equal dimensions may be lined up in a layer across the sheet, forming a cut line along the layer and across the sheet.

Automated imposition

Digital printing technologies often rely on raster image processors (RIPs or RIP engines) to convert vector image data to raster, or bit-map, data, which allows a printer to render the image as a pattern of dots or pixels. One problem that the present inventors recognized with conventional RIPs is that they have limited communications capabilities that can in some circumstances reduce their effective processing speed. Accordingly, at least some embodiments of the present invention allow controlling a RIP engine using two or more different RIP control entities.

Selectable control of raster image processor

A method of printing a multi-page job including producing separate non-bit mapped files for each page of the multi-page job, producing a page file for each page of the multi-page job, storing the page files in a memory and printing the page files in sequence. The page file may include color separations for the various colors to be printed on the page or other convenient forms of storage devoted to a single page. The page file may be in a bit mapped format or may be in the form of a continuous tone image in a format which can be easily converted into a bit-map format by the printer during the printing process. Preferably, the continuous tone image can be converted into a bit map for printing on the fly.
