Problems solved by technology

[0005] At home, some manufacturers have applied for the patent of rice paper for micro-spraying, such as the patent "Digital micro-spraying high-simulation copy method for coating rice paper and silk in Chinese calligraphy and painting" (application number CN200810116778), which provides a kind of micro-spraying suitable for micro-spraying. High imitation of the manufacturing method of coated rice paper and silk, this method first coats a layer of glue, and then coats the paint, this method is a sheet-fed coating process, this method cannot meet the continuous coating on the whole roll of machine-made rice paper The requirements of cloth production are not suitable for large-scale industrial production; the patent "reel rice paper for art reproduction and its manufacturing process" (application number CN201210577467) provides a kind of technology suitable for industrial continuous production of reel rice paper. It has solved the problem that sheet-fed coating cannot form large-scale industrialized operation, the production is time-consuming and laborious, the production cost is high, and the quality is difficult to meet the simulation requirements of industrialization for artwork reproduction. Problems existing during application are solved; the patent "infiltration coating method of inkjet printing material" (application number CN 200710063661) and the patent "inkjet printing coating and inkjet printing simulation material made of the coating" (application number CN200710063662 ) respectively disclose a coating method of an inkjet printing material, a kind of inkjet printing coating and the inkjet printing simulation material made thereof, to solve the serious ink problem caused by traditional rice paper or silk paper on a color inkjet printer Bleeding, poor contrast, and poor color saturation
These two patents solve the problems that occur when printing on traditional rice paper or silk paper, but do not solve the problems that exist in the application of domestically produced rice paper for micro-spraying.
At the same time, these two patents are only suitable for sheet-fed coating, and their stability is poor, so they are not suitable for industrial continuous production; the patent "an inkjet recording paper" (application number CN200810225556) and the patent "a high-simulation material for inkjet printing" (Application No. CN200810225553) respectively discloses a material suitable for inkjet printing
Among them, the patent "a high-simulation material for inkjet printing" discloses silk paper and silk cloth, and does not involve inkjet printing rice paper, and the patent "a kind of inkjet recording paper" only solves the problems caused by the slow ink absorption speed of the printing substrate. The ink that occurs interpenetrates and affects the printing quality of the pattern resolution, and does not solve the problems existing in the application of the domestically produced micro-spray rice paper; the patent "inkjet printing simulation material" (application number CN201120402556), the utility model Inkjet printing simulation materials can solve the problems of serious ink diffusion, poor contrast and poor color saturation caused by traditional rice paper or silk paper on color inkjet printers. The problem
[0006] It can be seen that the currently domestically produced rice paper suitable for micro-jet printing has problems such as: uneven printing color (print spots appear), poor color reproducibility, insufficient color gamut, poor pattern layering, and poor detail performance. and other problems; unstable production control, resulting in fluctuations in product quality, and when printing on different batches of paper with the same pattern, the color is inconsistent, there is a color difference, etc., there is still no good solution
