Description

Diamond canvas gluing method

Technical Field

The invention relates to the technical field of diamond canvas gluing, in particular to a diamond canvas gluing method.

Background

DIY diamond picture designers organically combine exquisite shining artificial crystal flat-bottom round drills or square drills with exquisite background patterns, while digital printing diamond canvas needs to be coated with glue when being attached to the drills, and can not be coated with glue when not being attached to the background patterns of the drills. The prior gluing process is a screen printing mode glue scraping process, and a screen printing plate is used as a manufacturing process: printing film or parchment paper (making the position of the sticking diamond into black color blocks), making a frame (made of aluminum alloy or iron), mounting a wire mesh in the frame for fixation, uniformly coating photosensitive glue, placing the printed film on the frame for exposure, washing the wire mesh frame with water, and reserving the glue scraping wire mesh frame for later use. And (3) a glue scraping process: the digitally printed diamond canvas is tiled on a desktop, a corresponding silk screen frame is manufactured in advance, glue is poured into the position to be glued manually, a special scraper plate is used for manually scraping the silk screen plate, the glue leaks to the diamond canvas from a silk screen hole to complete the gluing process, then the diamond canvas with the same pattern is scraped, and after the same pattern is scraped, special cleaning thinner is used for cleaning redundant glue on the silk screen plate and then the diamond canvas is stored for later use. The silk screen plate manufacturing and glue scraping processes are complicated, a large amount of labor and materials are occupied, more importantly, the used silk screen plate needs a large amount of special cleaning thinner when cleaning redundant glue, the volatility is strong, the smell is strong, the silk screen plate is harmful to the bodies of constructors, and the environment is polluted. The manufactured silk screen plate has a certain service life, and the scraping plate is worn on the silk screen plate because the silk screen plate is scraped by force. Because the silk screen plate has complicated manufacturing process and cannot be quickly manufactured in a short time, the screen plate with a corresponding style needs to be manufactured in advance, thereby greatly increasing the production cost and the stock of semi-finished products. Each production can be carried out in a certain number of styles in batch production to reduce the production cost, the production cost of the custom-made product of a client is too high, and the production period is too long, so that most manufacturers need to prepare a large amount of semi-finished products and finished product stocks. The pressure of manufacturers on stock is increasing due to the increase of new money.

The method for manufacturing the silk screen printing plate by adopting the glue scraping process has the defects of the following steps:

1. the register difficulty is high: the silk screen frame after making is done should be reflected very little by the expend with heat and contract with cold, can ignore, and the diamond canvas is obvious by the expend with heat and contract with cold, when the pattern rubber coating is printed to the diamond canvas of different batch different thickness, all can appear and the silk screen frame that corresponds has the error, greatly increased the frictioning and the version degree of difficulty, the frictioning often takes place to inaccurate (manual work batch production quality is difficult to manage and control), the digital stamp of diamond canvas on the existing market, what the effect is the best adopts dispersion aqueous heat sublimation ink, the diamond canvas of printing, the gorgeous lifelike diamond canvas of color is fine and smooth to feel, it is unable than similar that the diamond canvas (oily weak solvent ink) that the canvas printed is. The digital printing of thermal sublimation cloth will be with transfer machine high temperature chromophoric (about 240 degrees temperature keep about 30 seconds of time), and the shrink specific energy of cloth can reach more than 2%, and cloth high temperature itself will warp, because of it receives cloth thickness, transfer machine pressure, transfer machine temperature, rendition speed, transfer machine advance cloth pulling force and respond to, size after present branch art can't the complete control shrink brings a lot of difficulties for later stage silk screen frictioning to the version.

2. The periphery of the drill sticking position is free from redundant glue: the screen printing file manufactured by the prior art is a little larger than the periphery of the diamond canvas printed by a digital code. Therefore, the plate alignment and glue scraping are convenient, the gluing files are all formed in a square shape for the convenience of plate alignment, when the flat-bottom round drill is pasted, the corresponding color block background below the drill is in a square shape, the gluing is also in a square shape, after the round drill is pasted, glue with redundant areas is exposed outside, after the square drill is pasted, the glue with redundant areas is exposed outside on the pattern background and the outer edge of the square drill, and the gluing in the prior art is not attractive.

The diamond picture pattern corresponds to another group of spray heads, common printing color channels are printed, and conventional ink is selected for printing. And printing by a digital printing machine to obtain the diamond canvas printed with the two ink patterns.

And 3, scanning the diamond canvas printed with the two ink patterns by a scanning imaging system on the spreading machine, reading the pattern information of the spreading locating point on the diamond canvas, and generating a spreading locating point file.
