Problems solved by technology

However, if the starting point temperature T threshold If the design is too high, when the inkjet head prints the column and row blocks with higher printing density, the temperature of the inkjet chip may exceed the maximum temperature for normal operation due to the excessive temperature rise of the inkjet chip during printing. T max damage to the inkjet head

Embodiment Construction

[0010] The present invention is used to find the starting point temperature T corresponding to different printing densities threshold , so that the inkjet chip can be heated to the highest temperature T that can work normally when the inkjet head completes printing a block max , to optimize the print quality. When the inkjet head will print a lower print density block, the temperature of the inkjet chip will change less after it has been printed, so its starting point temperature T1 threshold It can be set higher, even so, when the inkjet head finishes printing, the temperature of the inkjet head can still be maintained at the highest temperature T at which the inkjet chip can work normally max . Relatively, when the inkjet head is to print a block with a higher printing density, the temperature of the inkjet wafer changes greatly after printing, so its starting point temperature Th threshold It must be set low so that the temperature of the inkjet head when it finishes pri...

Abstract

The invention relates to a method for finding the ideal initial temperature of ink-jet crystal plate of ink-jet head, comprising that: controlling said ink-jet head to print the data at a preset printing density; measuring the temperature of said ink-jet crystal plate; and comparing the measured temperature with a target temperature.

Description

technical field [0001] The invention provides a method for finding the ideal starting temperature of the ink-jet chip of the ink-jet head, in particular relates to a method for finding the ideal starting temperature of the ink-jet chip of the ink-jet head corresponding to a predetermined printing density. Background technique [0002] Inkjet printers provide high-level printing quality at a reasonable price and have become popular printing equipment in the information age. With the rapid advancement of technology, the pursuit of higher printing quality has become the goal of research and development by the information industry. Generally speaking, the printing principle of inkjet printers such as thermal bubble inkjet printers is to use the heating element on the inkjet head to heat the ink. When the energy is sufficient, the ink will generate bubbles and then eject the ink. However, part of the supplied energy is consumed by the ink, and part remains in the inkjet head, the...
