AI Technical Summary
Technical Problem
Existing digital printers have difficulty precisely controlling the deformation of socks on the cylinder when printing socks, leading to problems such as white gaps and overprinting, which makes it difficult to guarantee product quality, especially when printing in large quantities.
Method used
A digital printer with visual positioning is used to identify the position and shape of the sock heel, toe, and cuff through a camera, perform image alignment and deformation processing, and generate a new printed pattern to ensure that the image matches the shape of the sock.
Benefits of technology
It achieves 360-degree seamless printing, avoiding white gaps and overprinting, and improving print quality and efficiency.

Abstract
The application discloses a kind of sock product printing method, S1. Single-station or multi-station digital printer is selected, printer setting is carried out;S2. The calibration of planar coordinate system between camera sampling image and printer printing image is carried out;S3. The sock to be printed is sleeved on the cylinder of printer;S4. Visual system scans and acquires sock information, obtains sampling image;S5. The image to be printed is aligned with sampling image, and the heel, toe and cuff part in the image to be printed is removed, to generate new printing pattern;S6. New printing pattern is sent to printer;S7. Printer prints sock on cylinder.The application can automatically identify the heel, toe and cuff information of sock, through the alignment operation of the image to be printed and the sampling image, and through the cooperation of matting and deformation technical means, the printed image is matched with the real shape of sock, and the sock does not appear white and overprint during printing, which greatly improves product quality and yield.
