Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the embodiments and accompanying drawings, but the present invention is not limited thereto.

[0026] A color printing method based on the principle of optical interference, using an optical plastic film 1 as a carrier, a number of optical interference devices with a size of 200 nanometers to 100 microns and different reflection colors constitute basic pixels, and are arranged two-dimensionally on the carrier. Pixels make up color graphics.

[0027] Such as figure 1 As shown, in the color printing method based on the principle of optical interference, the basic pixels are composed of red optical film filter 2 , green optical film filter 3 and blue optical film filter 4 on optical plastic film 1 . The size of the red optical film filter 2, the green optical film filter 3 and the blue optical film filter 4 is 200 nanometers to 100 microns, all of which are composed of a first metal film 5, a poly...

Abstract

The invention discloses a color printing method based on an optical interference principle. In the color printing method, an optical plastic thin film is used as a carrier; basic pixels are formed by optical microstructure devices with different reflection colors, of which the diameters are of submicron scale; the basic pixels are two-dimensionally arranged on the carrier to form a color graph; the optical microstructure devices by which the basic pixels are formed are three optical thin-film interference filter units with red, green and blue reflection colors respectively; and various colors are formed by regulating the area ratio of the three filter units. The color printing method is based on the optical interference principle, pigment ink used in the conventional printing method is abandoned, and the color printing method is an environment-friendly technology, has high resolution and high color saturation and can be used for large-format production. Therefore, the color printing method is widely applied in the fields of printing, anti-counterfeiting, decoration, information display and the like.

Description

technical field [0001] The invention belongs to the field of color printing, and in particular relates to a color printing method based on the principle of optical interference. Background technique [0002] Printing has made great contributions to human progress and the spread of civilization. At present, printing is widely used in advertising, education, newspaper media and other industries. Existing printing methods are based on printing technologies such as gravure and letterpress of photosensitive materials, and use the absorption and transmission characteristics of ink to realize color images. However, there are disadvantages such as complicated process and serious pollution of printing materials, which have brought great pressure to environmental protection. [0003] In order to solve complex processes such as sensitization, developing, fixing, and washing in computer-to-plate-making and cumbersome processes such as light-proof operations, material science researcher...
