Abstract (en)
[origin: EP2392462A1] A printing method by a writing mechanism having either one print head with multiple arrays of side by side writing elements or a plurality of side by side print heads is applied to a writing mechanism comprising a rotating drum (3) supporting a photosensitive plate, at least two engraving laser heads (1,2) movable parallel to the axis of rotation (x) of the rotating drum (3), an array of laser diodes (5) on each laser head (1,2) and displacing means for the laser heads (1,2) in order to move them by a distance equal to the product of the number of laser diodes and the writing resolution. The laser heads (1,2) are side by side. The distances between the laser diodes (5) and a first laser diode (5) are not congruent modulo n. Spots that are generated by laser diodes (5) column by column, one per each laser diode, interlace to form a complete image.
