A printing apparatus includes a printing-medium conveyance unit, a printhead, and a control unit. The printhead has a first array of ejection ports ejecting a first ink and a second array of ejection ports ejecting a second ink, with the ports arranged in a printing-medium conveyance direction and the arrays arranged in a predetermined direction intersecting the conveyance direction. The control unit performs control to print an image of a foundation layer and images in stack and non-stack regions on the printing medium by having the conveyance unit convey the printing medium while scanning the printhead. The control unit performs control so that in printing in the non-stack region, the image of the foundation layer is printed using an ejection-port group in the first array at the same position as an ejection-port group in the second array for printing the image in the non-stack region, in an ejection-port arrangement direction.

In an example, an apparatus is described that includes a vision system and an image correction module. The vision system captures an image of a multi-lane print output. The image correction module receives the image of the multi-lane print output from the vision system and calculates a calibration to image data from which the multi-lane output is printed. The calibration minimizes visual variations between the multi-lane print output and a reference image.

A production installation (21) produces book blocks (22) in parallel from digital prints on basic sheets (24). Each book block has n book sheets aligned through rows (46) and columns (44) and each basic sheet has m book sheets (43) equal to the number m of book blocks to be produced. Under the control of an electronic unit (56), a point bonding group (51) dispenses adhesive strokes (61) on the basic sheets across the rows and/or the columns, a stacking group (52) stacks the basic sheets and forms a basic block (62) stabilized by the point bonds, while a separation group (53) cuts and separates the book blocks from the basic block along the rows and the columns for following treatments. The basic sheets have machine-readable basic codes (68) and the electronic control unit actuates the point bonding group, the stacking group and the separation group on the basis of information derived from the basic codes.

The invention relates to multilane printer for printing packaging material. The printer comprises a first lane for packaging material, a second lane for packaging material, and a printer head arranged in connection with the lanes. The lanes are arranged laterally offset in an overlapping manner, such that the printer head is able to simultaneously print on at least a portion of the packaging material travelling in each lane. The invention also relates to a multilane wrapping machine and a method for simultaneously printing a plurality of lanes for packaging material using one single printer head.
