A recording device includes a recording unit, a scanning unit, and a recording control unit. The recording unit includes first and second recording parts each having multiple discharge orifice rows that each have multiple discharge orifices arrayed in a predetermined direction. The first recording part and the second recording part are separated from each other in an intersecting direction that intersects the predetermined direction. The scanning unit performs recording scanning by moving the recording unit. The recording control unit performs recording of a region on the recording medium including one edge of the recording medium by the first recording part alone, recording of another region including the other edge of the recording medium by the second recording part alone, and recording of a region in between the two regions using both recording parts.

A coating of a coating medium, produced by means of a multichannel printhead (5) in a coating region (3) on a two- or three-dimensional surface (2) of an object (1), which is built up from coating points (8) along tracks (7) of one or more coating paths (6), characterized in that the starting coating point (HP) of at least one track (7) is aligned with a starting contour (AK) and an end coating point (EP) of the track (7) is aligned with an end contour (EK).

Mask entries for each of a plurality of passes over which print fluid drops are to be dispensed for printing an image are generated based on different types of masks and based on image data for the image. Print fluid drop dispensation for a pixel for which the mask entries for a given pass specify repeated print fluid drop dispensation is moved to a mask entry for an adjacent pass that does not specify print fluid drop dispensation for the pixel. Ejection of print fluid to print the image is caused based on the generated mask entries.

A printer for printing on a print medium as said print medium advances through a print zone, the printer including a number of print heads extending over the print zone, each print head including at least one nozzle array wherein at least two adjacent nozzle arrays overlap forming at least one stitching zone in the overlap region; and a printer controller for generating a sequence of nozzle firing commands for each nozzle array to selectively deposit droplets of print fluid on said print medium from said nozzle arrays in accordance with an image to be printed, wherein the printer controller further applies masks having decorrelated patterns to said sequence of firing commands for at least those overlapping nozzles of the nozzle arrays coinciding with the at least one stitching zone to obtain a predetermined optical parameter of the printed image in the stitching zone, irrespective of an offset between two adjacent nozzle arrays.

A method for printing a plurality of print jobs on a flat bed printer includes automatically grouping the print jobs into a plurality of consecutive container jobs, and for each container job automatically creating a digital plan of the flat bed, automatically defining a mask with cutting information according to the created plan, receiving the defined mask on the flat bed, receiving the media pieces on the flat bed positioned in according with the received mask, and unattended printing of the print jobs on the media pieces by the flat bed printer making use of the received mask. The automatic grouping includes gathering the group of print jobs due to the print job characteristics of each of the print jobs and/or the flat bed characteristics of the flat bed and ordering the consecutive container jobs due to the print job characteristics of each of the print jobs and/or the flat bed characteristics of the flat bed.

A printing apparatus includes a print execution section and a controller. The print execution section includes a printing head which has nozzles for discharging ink of specified color, the nozzles being aligned in a first direction; a head driver which drives the printing head to discharge the ink of the specified color thereby forming dots of the specified color on a printing medium; and a conveyor which conveys the printing medium relative to the printing head in any direction of the first direction and a second direction intersecting with the first direction. The controller is configured to: acquire object image data; generate a plurality of pieces of dot data, which represent formation states of the dots of the specified color, for a plurality of pixels by using the object image data; and print a printing image on the printing medium by using the plurality of pieces of dot data.

A fluid ejection apparatus is disclosed. One apparatus includes a first head chip and a second head chip. The first head chip includes nozzle groups A1, A2, B1 and C. The second head chip includes nozzle groups D2, E1, E2 and F. The nozzle groups A1, A2, B1, C, D2, E1, E2 and F eject fluid at an average usage rates A1, A2, B1, C, D2, E1, E2 and F, respectively. The average usage rate A2 is smaller than the average usage rate A1. The average usage rate B1 is smaller than the average usage rate A1. The average usage rate C is smaller than the average usage rate A1. The average usage rate D2 is smaller than the average usage rate E2. The average usage rate E1 is smaller than the average usage rate E2. The average usage rate F is smaller than the average usage rate E2.

There is provided a liquid droplet discharging control device for a liquid droplet discharging apparatus which includes a liquid droplet discharging head in which a plurality of nozzles discharging liquid droplets are formed, discharges liquid droplets while relatively moving the head and a medium in a direction intersecting a direction in which the nozzles are arranged. The liquid droplet discharging control device includes a controller that causes a first nearby nozzle, which discharges a dot adjacent to a dot row corresponding to a predetermined nozzle which is not capable of discharging a liquid droplet, to discharge a liquid droplet for a dot of a large size and that causes a second nearby nozzle, which is separated from the predetermined nozzle and discharges a dot adjacent to a dot row corresponding to the first nearby nozzle, to discharge no liquid droplet for a dot.

Replacement processing is executed when the number of times of permission for a pixel corresponding to an ejection defective nozzle in a mask pattern is larger than a smallest number of times of permission, of the numbers of times of permission for pixels corresponding to ejection normal nozzles.

In a method for printing, print images can be stored in the printer controller as bitmaps made up of bitmap data arranged in rows and columns. A printing element of a print head may be associated with a respective column of the bitmap. The same bitmap data of the bitmap may be associated with the printing elements of the print heads that are situated in an overlap region. The printing elements in the overlap region can be activated such that a print dot associated with a bitmap datum may be printed both by a printing element of the one print head and by a printing element of the other print head.
