METHOD OF MEASURING DISCHARGE AMOUNT FOR DROPLET DISCHARGE HEAD, METHOD OF DECIDING DRIVING VOLTAGE, DROPLET DISCHARGE DEVICE, AND APPARATUS FOR MEASURING DISCHARGE AMOUNT FOR DROPLET DISCHARGE HEAD

摘要

PROBLEM TO BE SOLVED: To carry out measurement discharge according to a pattern corresponding to an actual drawing, and to accurately measure a discharge amount for each of a plurality of discharge nozzles.;SOLUTION: The method of measuring a discharge amount for a droplet discharge head includes an impact-dot forming process of forming a plurality of impact dot lines DL by repeating a standard dot-line forming process of forming an impact dot line DL a plurality of times, an area measurement process of measuring the area of each of the impact dots D, a discharge-amount calculation process of calculating the amount of the discharged liquid for each of the discharge nozzles 21 based on the aggregate area of the individually measured impact dots D present across the plurality of impact dot lines DL, which aggregate area is obtained by assigning each of the impact dots D to the respective discharge nozzles 21. In the standard dot-line forming process, the measurement discharge is carried out by changing a plurality of measurement discharge patterns one after another. In the impact dot forming process, each of the standard dot-line forming processes is carried out by assigning a plurality of changing processes of changing the measurement discharge patterns to the individual standard dot-line forming processes one after another.;COPYRIGHT: (C)2010,JPO&INPIT
