Micro-coated pattern printing method and system

Abstract

This invention provides a printing method and a system for micro-coated patterns, in which, at least an ink jet head can print patterns arrayed in a matrix, in which, said head has multiple holes, said method and the system include: selecting jet holes for jet-printing on the head in terms of the distance between lines and adjusting said head to a suitable printing position to instruct the head to print according to the pattern, so this invention uses a same ink-head to correspond to patterns of different usages and adjusts the resolution of the ink jet and uses other jet holes working normally to continue the work when a hole is faulty or broken and control the work by time sequence fall among jet holes to replace traditional precision mechanical variable control and organizes a set of ink jet heads to a module to reduce the cost.

Description

technical field [0001] The present invention relates to a micro-coating pattern printing method and system, in particular to a micro-coating pattern printing method and system applied to matrix-arranged patterns. Background technique [0002] The pattern that needs to be printed in the industry often needs to have a specific form, such as a color filter element printed on a display or an organic light-emitting flat-panel display. The data processing method required by it is relatively simple and does not require a general image The inkjet printing method can only be completed after complicated processing procedures. [0003] The patterns required for printing in today's industries must be used in practical applications according to the patterns of different uses, and the angle of the rotating inkjet head corresponds to different pattern resolutions for pattern printing. When the hole spacing is changed, the inkjet head must be replaced to adapt to different patterns. This m...

AI Technical Summary

Problems solved by technology

like Figure 8 As shown, the nozzle hole spacing on the inkjet head 40 is smaller than the column-to-column spacing of the pattern 50 to be printed. In this case, even if the pattern is printed by rotating the inkjet head 40, the inkjet head 40 still exists The nozzle holes on the top do not correspond to the column position of the pattern 50 to be printed, which will lead to errors in the printing results

In addition, when a few nozzle holes of the inkjet head are faulty or damaged, it is necessary to replace a new inkjet head for pattern printing, which will also increase the production cost and is not environmentally friendly.
