A METHOD FOR PRINTING ON A PLURALITY OF SHEETS; AN INKJET PRINTING APPARATUS

摘要

The present invention relates to a method for printing on a plurality of sheets (20, 22). The method comprising the steps of: arranging the plurality of sheets on a support surface (14) of an endless conveyor, the plurality of sheets including a first sheet and a second sheet being arranged at a sheet-to-sheet distance (SI) between one another; advancing the plurality of sheets on the support surface in a conveying direction (T) along a print head assembly (12a-12d) for applying droplets of ink on the sheets; providing a suction force through perforations arranged in the support surface for holding the plurality of sheets on the support surface, wherein the suction force provides an air flow through uncovered perforations present in the sheet-to-sheet distance in a print region between the print head assembly and the support surface; and forming an image by the print head assembly on each of the plurality of sheets supported on the support surface of the conveyor by applying droplets of ink. The method further comprises the step of controlling the sheet-to-sheet distance in response to a dew formation attribute for indicating dew formation on the print head assembly.
