Embodiment Construction

[0036] Embodiments of the present invention will now be discussed in detail, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout. The embodiments are described below in order to explain the present invention by referring to the figures.

[0037] Such as figure 1 and figure 2 As shown, the inkjet printing device of the present invention includes a printing cart 2, on which a base plate 1 for installing an inkjet device is arranged, and a plurality of inkjet devices are installed on the base plate 1 for ejecting at least one color ink. The printing carriage 2 is installed on the guide rail beam 3, driven by the driving motor 6, the printing carriage 2 reciprocates along the first direction (main scanning direction) along the guide rail 4 installed on the guide rail beam 3, and the printing carriage 2 passes through the belt pulley The combination is connected with the drive motor 6, and the drive m...

Abstract

The present invention proposes a scanning inkjet printing method, which is characterized in that it includes the following steps of obtaining the step error value of the printing medium in the scanning direction; correcting the feed value of the printing medium in the sub-scanning direction according to the step error value; using The interpolation printing method prints the image onto a print medium. The inkjet printing method of the present invention can realize accurate and high-precision printing by measuring the conveying error of each part of the paper-feeding roller and compensating the conveying error of each part of the paper-feeding roller before performing interpolation printing.

Description

technical field [0001] The invention relates to a scanning inkjet printing method and an inkjet printing device, in particular to a scanning inkjet printing method and an inkjet printing device which use interpolation printing to improve the printing resolution of a printed image in the sub-scanning direction. Background technique [0002] Generally speaking, the inkjet printing device includes: a moving bracket, an inkjet inkjet device is installed on the moving bracket, so that the moving bracket with the inkjet inkjet device moves back and forth along the main scanning direction (Y direction), and during the movement ejecting ink droplets onto the printing medium; and a feed roller that conveys the printing medium in the sub-scanning direction (X direction). Printers using feed rollers require precise control of the feed rollers. If the control of the feed roller is unstable during printing, black lines may appear due to overlapping prints, or blanks may appear due to wi...
