Embodiment Construction

[0019] like figure 1 As shown, the hot melt inkjet printer includes a frame 10 (shown in phantom only) and houses a paper magazine 12 and a paper supply system 14 suitable for supplying paper sheets 16 to a print station 18 on the top side of the frame 10 . At printing station 18, paper 16 is sucked against the flat top surface (printing surface) of perforated paper support plate 20 by a vacuum system (not shown). The carriage 22 is arranged to run on the sheet 16 perpendicular to figure 1 Movement back and forth in the direction of the plane of the drawing. Thus, by activating the printhead 24, a column of images is printed on each stroke of the carriage 22. Next, the sheet 16 is advanced a step of the appropriate length in the direction indicated by arrow A so that the next column can be printed. An ejection system 26 ejects the sheets onto a tray 28 which, in the example shown, holds sheets 30 that have been printed. The sheet support plate 20 is temperature controlled ...

Abstract

In a hot-melt inkjet printer, a sheet (16) is advanced to a printing surface (20) where hot-melt ink is applied to the sheet, the sheet is heated above a second A first temperature for the temperature and a second temperature on the printing surface to prevent wrinkling of the sheet.

Description

technical field [0001] The invention relates to a method of processing an image receiving sheet in a hot melt inkjet printer, wherein the sheet is advanced to a printing surface where hot melt ink is applied to the sheet, and to a printer employing the method. Background technique [0002] US6196672B1 discloses a hot melt inkjet printer in which in order to accelerate heating of the sheet to a temperature ensuring proper curing of the ink a preheater is provided which preferably has a higher surface temperature than the printing surface. [0003] In printers in which sheets of paper or similar image-receiving sheets are used as recording media, the tendency of paper to wrinkle sometimes poses a serious problem. The wrinkling phenomenon is related to the fact that paper and similar materials tend to absorb moisture from the ambient air and expand and contract according to its humidity. In general, expansion and contraction are not isotropic, and are especially pronounced in ...
