UV (ultraviolet) ink jet printer bright surface line printing method capable of ensuring transparency and high color concentration of light reflecting film of processed piece

Abstract

The invention discloses a UV (ultraviolet) ink jet printer bright surface line printing method capable of ensuring transparency and high color concentration of a light reflecting film of a processed piece. The UV ink jet printer bright surface line printing method is characterized in that ink of each color in an ink jet module is stored in a pair of ink boxes which are symmetrically arranged relative to a center line of the ink jet module. The UV ink jet printer bright surface line printing method provided by the invention comprises the steps of (1) dividing a processed piece with a light reflecting film into multiple continuous line printing regions according to a transportation direction of the processed piece; (b) performing line printing operation for at least three times on each line printing region of the processed piece with the light reflecting film; and (c) switching on a UV lamp on one side of the ink jet module to solidify ink sprayed by the ink jet module when the last line printing operation of each line printing region is performed. The UV ink jet printer bright surface line printing method provided by the invention has the advantages that after the line printing of the processed piece with the light reflecting film surface is finished, the light reflecting film of the processed piece has the high reflectance and the high transparency, and patterns formed on the light reflecting film through line printing has the high color concentration.

Description

technical field [0001] The present invention relates to a UV inkjet printer bright surface printing method with transparency and high color density, especially a method of printing on the reflective film of the workpiece at least three times, and delaying the curing of the ink. A printing method in which the reflective film of a piece retains high reflectivity, high transparency, and high color density after printing. Background technique [0002] Since UV inkjet printers can print on many different materials or thicknesses of processed parts, in addition to providing faster printing speeds and achieving stable and consistent printing quality, its reliable performance also saves users Printing can be completed quickly without the work and time of making color separation screens, so that UV inkjet printers can bring a variety of economical and practical printing solutions and have a competitive advantage. [0003] Among the UV inkjet printers currently on the market, there i...

Problems solved by technology

[0004] However, when the above-mentioned UV inkjet printer completes pattern printing on a workpiece with a transparent reflective film surface, the reflectivity and transparency of the reflective film of the processed workpiece will be greatly reduced, and the printing on the reflective film of the processed workpiece The pattern produced also has a low color concentration, which leads to the poor quality of the pattern printed by the UV inkjet printer on the workpiece with a transparent reflective film surface

Therefore, in order to overcome this shortcoming, the traditional process is to use a cutting machine to cut the required pattern on a colored transparent film, and then paste the cut colored transparent film on the reflective film of the workpiece, so that the reflective film of the processed piece Form the desired pattern, but the steps of this method are complicated, and relatively cause problems of high cost and low yield
