Title:
IMAGE-PROCESSING DEVICE AND METHOD, PROGRAM, AND IMAGE-RECORDING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/012759
Kind Code:
A1
Abstract:
Provided are an image-processing device and method, a program, and an image-recording device that can suppress the occurrence of banding and colour irregularities without reducing productivity. The gradation values for each pixel in the image data for a first colour and a second colour, which are two differing colours from a plurality of colours, are converted to reflect differing types of nozzle ejection rate; and the converted image data is subjected to halftone processing. A first set of nozzle ejection rates reflected in the gradation values for the first colour is limited to comprising lower rates in the end nozzles at both ends of the nozzle row than the rates in the central nozzles. A second set of nozzle ejection rates reflected in the gradation values for the second colour comprises less difference between the rates in the end nozzles and the rates in the central nozzles when compared with the first set of nozzle ejection rates.
