Abstract: A dot matrix printing method is provided for printing an image on a printing medium with reduced banding, by moving, with respect to the medium, a printing head in a fast scan direction during a plurality of printing passes. The method comprises writing the image during the plurality of printing passes by mutually interstitial printing steps and/or interlacing steps, wherein the writing step comprises moving the medium with a transport distance step in a slow scan direction perpendicular to the fast scan direction between the printing passes of the at least two sub-images. The sum of all transport distance steps after writing one swath of each sub-image is exactly one head length, and the transport distance steps are performed in at least two different step lengths. An apparatus for dot matrix printing an image using sub-images, and transport distance steps with at least two different step lengths, is also provided.

Abstract: Printing media, a method and an apparatus for printing an image on a print medium are provided, the image having super-pixels made up of a combination of dots, wherein each of the dots is independently controlled with respect to the size of each dot, the density of each dot, and an overlap of at least two of the dots.

A printer provided with such a print head is also provided.

Abstract: A dot matrix printing method is provided for printing an image on a printing medium with a printing head (10) having a contiguous set of equally spaced marking elements (11). The marking elements available to be fired at firing moments are described as the active set. There is relative linear movement between the printing head (10) and the printing medium in a fast scan direction (Y). The method comprises the steps of: 1) dividing the image in a plurality of sub-images to be subsequently printed with mutually interstitial printing steps, and 2) using the printing head (10) to generate a plurality of equally spaced raster lines of dots on the printing medium in the fast scan direction (Y) by firing the marking elements (11), each raster line extending in the fast scan direction (Y), adjacent dots in the raster line not being generated by the same marking element (11).

Abstract: The present invention describes a method for printing, with one type of printhead, with a resolution that differs from the resolution of the type of printhead used. In the method according to the present invention, the speed in the fast scan direction is changed with reference to a reference velocity which the printhead is intended to be driven with, while preferably keeping the firing frequency of the sets of nozzles unchanged. The firing order of the may or may not be changed.

Abstract: The present invention provides a method of printing an image onto a printing medium using a printing system having an elongate printhead (10) with an array of marking elements (A, B, C, A, B, C) comprising at least one group of marking elements (A, B, C). The marking elements form at least one row (6, 7, 8), the direction of which forms a longitudinal axis of the printhead (10). The printhead (10) is driven in a fast scan direction (F) to print in one pass marks on the printing medium along one swath of print, and the printing medium and the printhead (10) are movable relative to each other in a slow scan direction (S) to print further swaths. The printing system is such that two adjacent marking elements of a group are firable with a time difference T but are not firable simultaneously without causing a printing defect.

Abstract: A method and apparatus for dot matrix printing of an image on a printing medium using radiation curable compositions is described. The image is printed using the radiation curable composition as at least one set of mutually interstitially printed sub-images, each sub-image comprising a set of dots, a dot consisting of a number of droplets applied on top of each other, each droplet being formed from one of a plurality of radiation curable compositions, the droplets mixing on the printing medium thus forming the dot with a specific grey level. Before printing a next sub-image from the set of sub-images, the dots of the previously interstitially printed sub-image are actively rendering non-migratory by exposing them to radiation.

Abstract: A dot matrix printer and printing method for being able to print a dot matrix (65) on a printing medium (66) using a plurality of marking elements (1-16) on a printing head (50) is described. A set of combinations of firing order of the plurality of marking elements (1-16) is determined as well as a sequence of relative translation movements between the printing medium (66) and the printing head (50) so that all the dots in the dot matrix (65) can be printed by application of each of the set of combinations, and any dot in the dot matrix (65) can be printed by at least a first and a second equivalent marking element (1 and 9) from a set of equivalent marking elements. For printing sets of dots in the dot matrix (65), a first equivalent marking element (1) is selected from the set of equivalent marking elements to print the set of dots as part of a first firing order.
