Method and printing device for the line-wise printing of a image composed of an assembly of image elements.

摘要

The line-wise printing of a image composed of an as. sembly of image elements (pixels) by means of a printing nead which embodies a row of N (N 2) printing elements which are arranged along a image line at a mutual distance from each other. The printing stroke is greater than the distance between two neighbonng ponting elements, as a result of which there is created at least one strip in the image in which there are pixel positions which are covered by m (2 ≦ m ≦ N) printing heads. For this stno (or stnos) severai options are then presented for printing the pixels situated within them. A pixel in such a strip can now be pnnted by one or by several of these m pnnung elements, the allocation of one or more of these m printing elements to a position being capable of being chosen as fixed or vanable. Furthermore, it is possible, if a pixel can be printed by several printing elements, to distribute the pixel printing values of the relevant pixel point over these several printing elements according to a fixed or variable distribution code.
