Embodiment Construction

[0047] exist Figure 1a In the present invention, the deposition medium 100 is used to receive a predetermined amount of a substance at an initially determined deposition point on the medium. In the following description, the term "deposition" will be used to refer to the transfer of a certain amount of substance from the ejection head 10 onto this medium 100, it should be understood that the term "deposition" includes printing but more refers to enveloping. To this end, the spray head 10 is translated relative to the medium 100, parallel to the receiving surface of the medium while still maintaining a constant distance from this surface. The spray head 10 moves relative to the media 100 in two directions: the transverse direction T and the longitudinal direction L. These two directions may be parallel to the edge of the media 100 . Most commonly, they are perpendicular to each other, especially if the medium 100 is rectangular. It is assumed below that the movement of the s...

Abstract

The invention relates to an ink-jet printing deposition method including a compensation of deviations (delta l1, delta l2, delta l3,... ) of ejection nozzles (1, 2, 3...) carried by a printing head (10). To this end, the deviations are measured first at the moment of the deposition, and then, during the deposition, each nozzle is activated when it shows a shift in relation to the point on a support where the substance is to be deposited, substantially opposite the deviation of said nozzle. Said depositions carried out in this way do not comprise accidental Moire patterns.

Description

technical field [0001] The present invention relates to a deposition method for inkjet printing. Background technique [0002] The inkjet printing method is well known and widely used, not only for printing text or images on all types of surfaces, but also for a variety of other applications. They consist of a movable spray head which moves relative to the receiving medium and which has at least one nozzle which is controlled to discharge a predetermined amount of substance at controlled moments during the movement of the movable spray head. Each nozzle is aimed at the medium so that the ejected quantity of material reaches an initially defined point of impact on the medium. The medium is also adapted to allow an amount of substance received at a point to remain at that point without any subsequent diffusion or movement of the substance across the medium. [0003] Substances deposited in this way can vary in appearance and type, depending on the application involved. Exam...
