The invention relates to the technical field of a preparation method of a thin film material, and in particular relates to a preparation method of a polyethylene flexible printing environment-friendly thin film. The preparation method comprises the following steps of: uniformly mixing polyethylene particles and polyethylene to obtain a mixture; heating and melting the mixture by a film blowing machine and blowing a thin film; slitting the thin film by a slitting machine; coating the slit thin film, wherein printing ink and solvent used for re-treating the coated thin film are waterborne printing ink and solvent without methylbenzene; slitting the coated thin film again; making bags for the thin film by a bag making machine; and finally, obtaining a finished product, testing and putting in a storeroom. Compared with the prior art, according to the preparation method provided by the invention, not only is not the environment polluted, the environment extremely protected and the generation of exhaust gas matters greatly reduced, but also the product quality is ensured. 8 color printing rolls can be quickly switched. The preparation method is simple, low in cost and strong in industrial accessibility.

The invention provides an intelligent laser color printing system based on the Internet of Things. The system comprises a server, a preset module based on a plurality of control parameters of a printer and a corresponding model of corresponding printing definition are stored in the server, and according to the relevance between the preset value of the control parameters of the printer and the printing definition value, each action element of the printer is adjusted in real time; a detection element corresponding to various control parameters is arranged in the printer, and is used for comparing a real-time detection result with various control parameters pre-stored in the server to determine whether the printing definition is within a preset range, if yes, printing is performed according to the current state of the printer, and if not, each element of the printer is adjusted through an adjusting module. According to the method, the function model based on big data and a storage database are constructed, so that the state data of the printer can be obtained from a quantitative angle, and the optimal printing state based on the Internet of Things is achieved by comparing the state data with a reference database.

The invention relates to a forming process of a three-dimensional window type scene-permeable label, which comprises the following steps: S1, front printing: selecting a shrink film material, and printing basic information of the label by using gravure matte varnish and flexographic printing; s2, shielding printing: adopting a multi-layer white ink matching line anilox roller to perform printing, respectively showing ink loading quantity from shallow to deep, highlighting layers and drawing one or more developed outlines, so that the shrink film cannot be completely transparent visually; and S3, back surface printing is carried out, an anilox roller is used for carrying out YMCK four-color printing on the back surface of the label, when the label is used, the outline forms a window, and the patterns printed on the back surface penetrate through the product and are combined with the window to form a three-dimensional transparent scene. Compared with the prior art, the label has the advantages that the self identification requirement of the label is met, transparent shadows can be appreciated at different angles and are attractive, so that the curiosity of a user is increased, the attention can be effectively distracted, the visual fatigue can be effectively relieved, in addition, the transparent shadows are clear, and the softness and flatness of the label are relatively good.

The invention discloses a tetra-coordinated octahydroxyquinoline boron compound, preparation method and application of the compound, belonging to the technical field of stimulus-response luminescent materials. Three single crystals of the compound can be obtained through different preparation methods, show double-fluorescence emission and have typical homogeneous polymorph property. After a solidsample of the compound is mechanically ground or subjected to external force, fluorescence light can be changed, and after the ground solid sample is subjected to heat treatment, the fluorescence light can be restored, so that high-efficiency restorable mechanophore property. The solution of the compound is heated to a certain temperature, is written/printed to paper, and can shown different fluorescence lights at room temperature, so that the creative application of color printing of single ink can be initially achieved. In conclusion, the compound has wide application prospects in the fieldsof color printing, anti-counterfeit materials, pressure sensors, optoelectronic devices and the like.

The invention relates to the field of three-dimensional (3D) printers, in particular to a 3D printing nozzle module for plastic fibers with three-primary colors and two-selected colors. The 3D printing nozzle module comprises a main body, wherein the main body is provided with three or two V-shaped channels; and three or two feeding mechanisms simultaneously or alternately enter one nozzle head inlet, so that an alternate switching and combination process of the three-primary colors and the two-selected colors is realized. In an experiment, a nozzle sprays a color achieving an ideal color effect. By combining the conditions with existing applied software and a separated double-nozzle 3D printer, the two single feeding mechanisms can be simultaneously fed into one nozzle module to be used,and the three-primary colors can be controlled without developing a new program; and by adopting the scheme, multi-color printing can be conveniently realized for 3D printing.

The invention discloses a seamless multicolor printing process and a quick-drying printing ink formula employing the same. The seamless multi-color printing process comprises the following steps of: (1) preparation, (2) modulation of printing ink, namely modulating quick-drying printing ink with different colors, (3) determining of a printing color sequence, (4) trial printing, (5) inspection, (6) white spraying, (7) determining of a printing area, (8) formal printing, (9) black spraying, (10) cutting, (11) dust removal, (12) protective oil spraying, and (13) finished product inspection. Therefore, four-color printing of silica gel is achieved, high definition, high color saturation and uniformity of color images printed on the surface of a silica gel product are guaranteed, the printing speed of formal printing is increased, operation and maintenance are simplified, the printing quality is guaranteed, the production cost is reduced, the printing ink is good in quick drying property and fast in printing ink release, and can adapt to high-speed printing, and the speed of high-speed printing and the quality of the printed product can be guaranteed.

The invention discloses a novel printing process for forming printing patterns on a foaming layer. The novel printing process comprises a ground color printing mechanism, a foaming layer printing mechanism, a digital jet drawing mechanism, a foaming mechanism and a conveying mechanism. The ground color printing mechanism, the foaming layer printing mechanism, the digital jet drawing mechanism andthe foaming mechanism are arranged above the conveying mechanism in turn. Therefore, the printing production system uses the digital jet drawing mechanism to form the printing patterns on the foaminglayer so that the printing and dyeing speed is high, the process flow is greatly shortened, and the printing effect is good and the color is vivid and gorgeous.
