Embodiment Construction

[0064] figure 1 It is a diagram showing the configuration of the image recording device 1 according to the first embodiment of the present invention. The image recording device 1 is a sheet-fed printing device (so-called inkjet printer), and sequentially records color images on a recording medium 9 serving as printing paper by ejecting tiny droplets of ink. on a plurality of recording media 9 .

[0065] Such as figure 1 As shown, the image recording device 1 has: a moving mechanism 2 that moves a plurality of recording media 9 along figure 1 The movement direction of the (+Y) direction in the middle moves; the ejection unit 3, which ejects tiny droplets of ink toward the recording medium 9 in the process of being conveyed by the moving mechanism 2; the supply part 51, which supplies the recording medium to the moving mechanism 2 9. The discharge unit 52 receives the recording medium 9 after printing from the moving mechanism 2 ; and the control unit 4 controls the above-men...

Abstract

An image recording apparatus generates black, cyan, magenta, and yellow halftone image data from a multi-tone color image. When the cyan halftone image data is generated, the size of a cyan dot to be formed at a target pixel position is provisionally determined and added to the size of a black dot to obtain a total dot size. When the total dot size is less than or equal to a first threshold dot size, the cyan dot size is determined to be the provisionally determined size, and when the total dot size is greater than the first threshold dot size, the cyan dot size is determined to be the largest dot size within the range of a difference between the first threshold dot size and the black dot size. It is possible to prevent excessive overlapping of black and cyan dots, thereby suppressing poor color reproduction and cockling.

Description

technical field [0001] The present invention relates to an image data generating method and an image data generating device for generating halftone image data by performing halftone screening process on a multi-grayscale color image, and an image for recording an image on a recording medium Recording method and image recording device. Background technique [0002] Conventionally, there has been used an image recording apparatus that records a color image on a recording medium using an inkjet method by relatively moving an ejection portion that discharges fine droplets of ink into an array. Multiple nozzles. Based on the halftone image data generated by the halftoning process, ink dots (dots, ink dots, halftone dots) are formed at each pixel position on the recording medium to record a color image. In such an image recording device, the dots of inks of various colors mostly overlap at each pixel position on the recording medium, which may cause color cloudiness, poor color ...
