Abstract

The invention discloses a film inspection device, comprising a table body, the table body includes a table top and table legs; a light box, the bottom plate of the light box is fixed on the table top, and A white light source; the top of the light box is a white light-transmitting board. There are also dimmers and cooling fans. The invention effectively solves the problem of high labor intensity and easy fatigue during long-term and careful inspection of film sheets, ensures the inspection effect, and can adjust the intensity of the light source according to the different densities of film sheets, has good heat dissipation performance, and is simple in structure. Easy to use.

Description

technical field [0001] The invention relates to the field of printing and plate making, in particular to a film inspection device. Background technique [0002] The film used in printing and plate making is called film, and it can be printed on the PS plate with the film, which is equivalent to the negative of a photo, and it plays a linking role in printing. Although digital-to-plate technology (CTP) is developing very fast, it will take some time for popularization and application. Now the film in the traditional printing process is still one of the key links in printing. Without the film, it is impossible to print and print. In the past, the film was completed by photo-plate making; at present, the film is interpreted by the phototypesetter into the dot matrix data of the digital image through the raster image processor (RIP), and then the result of the typesetting is color-separated and output to the The film is finished. In order to eliminate all kinds of unfavorable...
