Technical Field
The invention belongs to the technical field of elliptical printing machines, and particularly relates to a seamless stripe printing system of an elliptical printing machine.
Background
The silk screen printing is to cover a plate with a gap on a printed object, such as clothes, then pour the colored paste on one end of the plate, then use a scraper to scrape the colored paste towards the other end, and the colored paste is printed on the surface of the clothes when being scraped through the gap area, so as to form a pattern corresponding to the gap. The stripe pattern is a common pattern, and a certain aesthetic feeling can be generated through the thickness and the color of the stripe.
When stripes with various colors are required to be printed on the clothes, because only one printing mechanism is provided with one plate at present, in order to prevent slurry with various colors from mixing together, slurry with one color can be placed on the plate, so that the number of printing mechanisms is required for each color, and the number of printing mechanisms is required for each width, thereby in turn limiting the design of stripe patterns, particularly the matching of the stripe colors and the stripe thicknesses.
