20100039462 | LIQUID-DISCHARGE-FAILURE DETECTING APPARATUS, INKJET RECORDING APPARATUS, AND METHOD OF DETECTING LIQUID DISCHARGE FAILURE - A light-emitting element emits a beam onto a droplet discharged from a nozzle. A light-receiving element receives a scattered light generated by scattering of the beam by the droplet. A discharge-speed controller controls a speed of discharge of the droplet from the nozzle to be set at the speed outside a normal discharge-speed range that is determined depending on a viscosity of a liquid. Finally, a failure detecting unit detects a liquid discharge failure from data of the scattered light received by the light-receiving element. | 2010-02-18 |
20100039463 | WHITE INKJET INK IMPROVED FOR DISPERSION STABILITY - An inkjet printing method includes in order the steps of: a) providing to an inkjet printer one or more colorless liquids and a white ink including a pigment with a refractive index greater than 1.60; b) mixing the white ink in a controlled amount with the one or more colorless liquids to form a white ink-mixture wherein the viscosity is reduced by at least 5 mPa·s by reference to the white ink when measuring the viscosity at 40° C. with a Brookfield DV-II+Pro at 12 rotations per minute; and c) printing the white ink-mixture with the inkjet printer onto an ink-receiver. Additionally, a color inkjet ink set includes the one or more colorless liquids and the white ink, and an inkjet printer for use in the inkjet printing method. | 2010-02-18 |
