VERFAHREN ZUM AUFZEICHNEN VON INFORMATIONEN
摘要:
In order to record information on a recording substrate (2), a printing head (1) with a number (a) of printing elements (11) is moved to and fro across printing positions (22, 23, 24) by lines. Partial numbers (n) of the printing elements (11) form sub-groups (15) in accordance with a predetermined individual print line which are allocated to the printing positions (22, 23, 24) of a printed line (29) and formed by at least partly differing printing elements (11). The printing elements (11-1 to 11-4) of the sub-group (15) concerned are selectively controlled at the printing positions (22, 23, 24) in accordance with the printing data to produce a model print line (31). On the completion of a subsequent model print line (33), the formation of a subsequent model print line (34) is determined at least on the continuation side on the formation of the previous print line (29). Stripes caused by line continuation errors or inking ribbon structural errors are distributed with a vertical displacement over the printed image by the process of the invention; unlike the case with uniform structures, the human eye hardly takes notice of such distributed faults.
