The technical solutions of the two patent applications cannot change the distance from the headstock to the surface of the printing material according to the thickness change of the printing material, and further cannot guarantee the printing effect.
Wherein, the reason that can't change locomotive to printing material surface's distance according to printing material thickness variation leads to unable assurance printing effect lies in:
inkjet printing requires that the printing head be at an optimal distance from the substrate to provide a print of sufficiently high print density and resolution. Too far or too close a distance has an effect on the quality of the print, which can result in too large a dot spacing and blurred images, and too close a distance can result in overlapping dots and excessive image color. However, since the number of the printing stock is relatively large, the thickness of the printing stock is also various, and the distances between the printing stock with different thicknesses and the printing head are different, so that the printing effect is affected.
In this regard, there is a need for a digital printer with a head that can be adjusted in height to accommodate different specifications of printing stock.

The technical scheme is that although the height of the printing module spray head can be changed, the height of the printing module spray head is changed by changing the screwing depth of the adjusting screw, and the printing module spray head is of a pure mechanical structure, when a printing stock is changed each time, the screw is manually screwed to change the height of the printing module spray head, so that time and labor are wasted, the adjusting process is totally dependent on the experience of an operator, and the adjusting precision is difficult to guarantee.
