摘要： A machine (1) is equipped for printing a pattern on a substrate (20). The machine (1) comprises a table (10) for supporting and moving the substrate (20), and a print head (30) for firing ink droplets towards the substrate (20). Further, the machine (1) comprises a cover plate (40) which is arranged such as to encompass the print head (30), wherein the print head (30) partly extends through a hole in the cover plate (40). During a printing process, evaporation of solvent which is part of the ink droplets starts as soon as the ink droplets land on the substrate (20). The presence of the cover plate (40) has an equalizing effect on the evaporation rate over the printed pattern. As a result, a height distribution of all printed elements of the pattern is within predetermined limits, once the elements have dried up.

摘要： During the manufacture of PoIyLED displays, printed elements of the LEDs are obtained by first printing bottom element layers (23a) and subsequently printing top element layers, according to a predetermined pattern. When the dimensions of a PoIyLED display are relatively large, the printing process of each layer (23a) takes place in several strokes. In order to prevent a situation in which unacceptable differences in the height distribution of the obtained elements exist, the layers (23a) of elements which are located at a circumference of a group of elements associated with one printing stroke are printed in two steps. During a first printing stroke, a first portion of the element layers (23a) is printed, whereas during a subsequent printing stroke, the remaining portion of the element layers (23a) is printed. Consequently, the printing strokes are performed in an overlapping manner.
