摘要： The invention relates to a method of controlling a digital inkjet printer 3 for printing images on an image receiving medium 2 up to a maximum medium width. The digital printer 3 is arranged to operate in a selected first print mode which is characterized by a first speed in a main scanning direction X for at least one carriage 5,12. A digital image is received and a print setting that the digital image is planned to be printed in an enhanced adhesion print mode is received. A time period needed for a pass in the main scanning direction X is extended
c1) by lowering a speed in the main scanning direction X from the first speed to a second speed, and
c2) by enlarging the pass width up to a maximum medium width in the main scanning direction X and/or by temporarily stopping the at least one carriage 5,12 at an end of the pass.
Marking material is ejected during the pass on the image receiving medium 2 by means of a print head 4a,4b,4c,4d,4e at the second speed within the extended time period, and Is cured by means of a UV curing device 11 at the second speed within the extended time period. The invention further relates to a digital inkjet printer configured to perform the above mentioned method.

摘要： A method for printing a digital image in swaths with a swath time corresponding to the width w1 of the digital image on the image receiving medium 2 in the main scanning direction X. The print controller 10 issues a trigger that a spitting action for at least part of the printing elements 8 of the print head 4a, 4b, 4c, 4d, 4e needs to be performed. A swath time of subsequent swaths is gradually increased until the print head reaches a maintenance tray 11 at a side of the print surface 1. The print head stays at the maintenance tray 11 until air between the print head and the maintenance tray 11 has approximately reached a standstill. Then the at least part of the printing elements 8 of the print head are spitting marking material in the maintenance tray 11. After the spitting the swath time of subsequent swaths is gradually decreased until the swath time is corresponding again with the width w1 of the digital image on the image receiving medium 2 in the main scanning direction X. The invention further relates to a digital inkjet printer configured to perform the above mentioned method.

摘要： Method for matching colours between different print modes in a printing system, the method comprising the steps of: when printing in a first print mode, mapping colours specified in first image data to colours to be specified in second image data according to a first mapping; and when printing in a second print mode, mapping colours specified in the first image data to colours to be specified in the second image data by applying a correction mapping in conjunction with the first mapping.
