A digital inkjet printing method for embroidered cloth that can realize intelligent visual guidance

Abstract

The invention discloses a digital printing method for embroidered cloth that can realize intelligent visual guidance. The embroidered cloth is cross-stitched, and the specific steps are as follows: Stop after the digital printing area; b. Use a long linear array CIS camera for image acquisition; c. After collecting the image, send the data to the PC for image processing; d. Locate all the directions for pattern printing on the cross-stitch cloth image grid area; e. According to the texture of the embroidered cloth positioned by the visual guidance, control the inkjet print head to print the correct pattern at the exact position; f. Then return to step a. Compared with the prior art, the present invention realizes the intelligent visual guidance and positioning function of the digital jet printing machine by adding the machine vision of the long line array CIS camera, so that the digital jet printing equipment is no longer affected by the material deformation of the printed object and the mechanical movement error of the equipment itself. Factors, so as to achieve accurate pattern printing.

Description

technical field [0001] The invention relates to a spray printing method, in particular to a digital spray printing method for embroidered cloth which can realize intelligent visual guidance. Background technique [0002] Cross-stitch printers are referred to as universal printers for short. They are usually composed of a belt guide machine and a printing module. They can be used in large-format and super-long-format printing tasks. It is a non-contact inkjet printing high-tech digital printing with objects. equipment. The main function of the cross-stitch printer is to print the embroidery pattern on the cross-stitch cloth, so that there is no need to look at the drawings during the embroidery process, and there is no need to draw grids and dot grids. Embroidery greatly shortens the embroidery time and reduces the difficulty of embroidery. [0003] It is necessary to print the pattern on each square grid accurately and without deviation. However, since the cross-stitch cl...

Problems solved by technology

However, since the cross-stitch cloth is a flexible material and has ductility, the texture of the longer and wider cloth (usually about 1.5m in width) will be distorted when it is sent to the printing area through the belt guide machine. The flatness of the cloth cannot be guaranteed during the printing process, and the distance between the printing grid and the adjacent small holes between the grids on the cross-stitch cloth is very narrow, usually about 1mm, and the positioning requirements are very high. It is easy to print on adjacent squares; coupled with the motion error between the tape guide machine and the printer itself, the actual step size of the cloth movement will be inconsistent with the theoretical step size

The above-mentioned factors cannot be solved according to the current technical means, which will eventually lead to the inability to accurately print the positioning printing pattern on the cross-stitch cloth
