A pearlescent printing process for making pearlescent printed products comprising the steps of:
And (3) preparing a coating: weighing the silver onion powder, the gloss oil and the curing agent according to the formula amount, and uniformly stirring to obtain the pearlescent coating;
Plate making: manufacturing a screen plate with patterns by a photosensitive plate making method, and installing the screen plate on printing equipment;
Screen printing: taking the plastic injection molding part 10 as a printing stock of printing equipment, pouring pearlescent paint at the front end of a silk screen of a screen plate, applying downward silk screen pressure by utilizing a scraping plate, and extruding the pearlescent paint on the silk screen to the surface of the plastic injection molding part through meshes of the silk screen; printing a pearlescent layer on the surface of the plastic injection molding by utilizing the screen after sizing, and pre-treating the surface of the plastic injection molding before printing, wherein the pre-treating mode comprises at least one of flame spraying treatment, air spraying treatment and oil spraying treatment; by adopting the mode, the adhesiveness of the surface of the plastic product can be effectively improved, so that the printing quality is ensured.
And (3) drying: taking down the printed plastic injection molding piece 10, and putting the plastic injection molding piece into a drying device for drying and curing to form a pearlescent layer 20 to obtain a pearlescent printed product;
Cutting: and trimming the pearlescent printed product to obtain a finished product. The pearlescent printing is a special printing technology using pearlescent ink, and the pearlescent ink has pearl inside the body of a freshwater mussel natural luster to enable the packaging printed matter to display colorful colors like the precious luster of the pearlescent, is noble and elegant, has the glittering effect of metal pigment, can generate soft luster of natural pearls, can generate multi-level reflection when being irradiated by sunlight, and can display soft and attractive or colorful luster and color through interaction of reflected light. Therefore, the pearlescent printing process is widely applied to the printing of various plastic products, and is characterized by high printing speed, good printing effect, low cost and the like. The pearlescent printing generally adopts a screen printing process, and comprises the following main steps: design of patterns, plate making, printing, drying, cutting and the like, wherein the plate making is a key step of a screen printing process, and the quality of the plate making directly influences the quality of a printing effect.
Optionally, the plate making process comprises the steps of:
Stretching the net: placing a net frame on a net stretching machine, and selecting net cloth needing meshes to stretch the net; the screen frame is cleaned, then placed on a screen stretching machine, and screen cloth with 60 meshes or 40 meshes is stretched on the screen frame to obtain a screen plate;
Edge sealing adhesive tape: sealing the edges of the periphery of the screen plate by using an adhesive tape; the four sides of the screen plate are wrapped by adopting the silver dragon adhesive tape so as to protect the firmness of the mesh cloth and the Nanbao glue and improve the attractiveness of the screen plate;
Cleaning the screen printing plate: cleaning the screen printing plate by using a degreasing agent; each screen printing plate is required to be cleaned by clean water after being brushed by a degreasing agent pneumatic brush, and is placed in a water tank to be drained;
Baking the screen printing plate: placing the cleaned screen plate into an oven for baking; uniformly inserting the baking oven into the middle of the baking oven according to the grids in the baking oven, wherein the temperature of the baking oven is controlled within 38 ℃;
And (3) screen plate sizing: scraping photosensitive glue on the front and back surfaces of the baked screen;
Sun screen printing plate: sticking a film on the back screen cloth coated with the screen plate by using a 3M adhesive tape, and putting the film on glass of a plate copying machine for exposure;
Developing in water: taking down the film after exposure, putting the screen into water for development, flushing a fine manuscript surface of the screen with a water gun, and putting the developed film into an oven for baking; before baking, checking the developed screen, and baking the qualified screen;
Checking and repairing: checking and repairing the dried screen; checking the baked screen again, and repairing the position with ink leakage with photoresist;
The exposure is firm: the repaired screen is put on the plate copying machine again, and the front and the back of the screen are exposed for 160 seconds, so that the firmness of the manuscript surface is improved.
Optionally, the screen plate sizing process comprises the following steps:
And (3) primary sizing: pouring the photosensitive glue into a scraping groove, placing the screen plate on a wood frame in an inclined way by 35 degrees, scraping glue for the first time on the back and the front of the screen plate by using the scraping groove, optionally scraping the glue for 3 times on the back of the screen plate by using the scraping groove, scraping the glue for 3 times on the front of the screen plate, and scraping the glue for sealing the screen again on the back of the screen plate; putting the dried product into an oven for drying;
And (5) sizing for the second time: after the dried screen plate is scraped for the second time, optionally scraping 6 times of glue on the back surface of the screen plate by a scraping groove, scraping 4 times of glue on the front surface, and drying in an oven;
And (3) third gluing: after the dried screen plate is scraped for the third time, optionally, scraping 6 times of glue on the back surface of the screen plate by a scraping groove, and then putting the screen plate into an oven for drying. After the third baking, the screen plate is glued, and the screen plate needs to be glued in places with weaker light rays in the dark during gluing. The application uses three glue applying processes to ensure the glue applying effect of the screen printing plate, thereby ensuring the plate making quality.
It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the application, which are all within the scope of the application. Accordingly, the scope of protection of the present application is to be determined by the appended claims.
