Double-color printing nozzle permutation and combination structure and printing method

Abstract

The invention discloses a double-color printing nozzle arrangement and combination structure, which comprises a nozzle mounting bottom plate, a large image printing nozzle assembly arranged on the nozzle mounting bottom plate and a small image printing nozzle assembly arranged on the nozzle mounting bottom plate, and is characterized in that the large image printing nozzle assembly is used for printing a large image on a whole-surface jet printing medium, and the small image printing nozzle assembly is used for printing a small image on the whole-surface jet printing medium; and the small image printing nozzle assembly is used for printing the prominent small image on the whole surface of the jet printing medium. The nozzle mounting bottom plate is provided with a large-image nozzle assembling hole for mounting the large-image printing nozzle assembly and a small-image nozzle sliding groove for mounting the small-image printing nozzle assembly side by side, and the small-image printing nozzle assembly is slidably arranged in the small-image nozzle sliding groove. According to the invention, a large-image printing mode and a small-image printing mode are combined and arranged, the arrangement of the large-image printing nozzles can cover a whole-surface jet printing medium, the arrangement of the small-image printing nozzles only needs to cover the width of a small image needing to be highlighted, and the small-image printing nozzles can automatically move, so that the small image can be printed and highlighted at different positions of the whole-surface jet printing medium.

Description

technical field [0001] The invention relates to the technical field of digital inkjet printing, in particular to an arrangement and combination structure of two-color printing nozzles and a printing method. Background technique [0002] Some industries in the field of inkjet printing use two-color or multi-color printing. One of the tones is specially used to highlight the effect of small pictures of different colors in the main color printing area, such as LOGO or company name, etc., to highlight the small picture in the main color printing area. The position in the spray area is flexible and changeable. In order to meet the printing requirements of different locations, the printing trolley is usually filled with a row of small image printing nozzles to cover the entire surface of the printing image, and then drives different The nozzles will print correspondingly, and the other small image printing nozzles that are temporarily unused will be shut down. However, the nozzle...

Problems solved by technology

However, the nozzles that do not work frequently are prone to blockage and cause poor printing quality. In severe cases, the nozzles must be replaced. The nozzles are expensive equipment consumables. The number of nozzles directly affects the purchase cost of the customer, and the replacement of the blocked nozzles will increase the maintenance cost of the customer. and equipment production efficiency, the existing technology needs to be improved
