Title:
INKJET PRINTING DEVICE AND JET QUANTITY INSPECTING METHOD
Document Type and Number:
WIPO Patent Application WO/2010/005011
Kind Code:
A1
Abstract:
Provided is a technology of uniformizing in-plane distribution of a jet quantity of a printing device. A color ink is jetted onto a substrate (5) from a plurality of nozzle ports (22), and the rear surface of the substrate (5) is irradiated with measuring light by means of an illuminating device (16). The transmitted measuring light is received by a light receiving device (25), and chromaticity and luminance are measured. Since deficiency/excess of a jet quantity of the nozzle port (22) is recognized when the measurement value is compared with a reference value, parameters of a voltage to be applied to a piezoelectric element can be corrected and the jet quantity can be set equal to the reference value.
