Description
Technical Field
The invention belongs to the technical field of printing, and particularly relates to a fine casting embossing thermoprinting product and a printing technical scheme of the product.
Background
The existing embossing bronzing needs to be designed and manufactured by a special plate making factory, the embossing bronzing has a production cycle problem in actual production, the cycle from the order placement to the plate making company to the receipt of the manufactured embossing bronzing by a printing enterprise is slightly long (generally about 3-7 days), occasionally, the problem of delayed delivery also exists, the problem has no autonomy on the production plan arrangement of the printing factory, and the printing factory is relatively passive in production and cannot actively respond to the market for some printing products urgently needed by customers. Meanwhile, the cost of the traditional embossing plate stamping and plate making is high, and the cost of the stamping plate and the embossing bottom film is about 50 yuan/cm; taking 3-4 patterns with the size of 2 cm for each unit hot stamping as an example, the cost of a set of gold stamping plates and a matched resin positive film in the proofing process needs to be about 2500 yuan, and the gold stamping plates can be generally used only once (the patterns needing gold stamping are different due to different design patterns in the next proofing). In addition, the conventional embossing and stamping on the production process has the defects that large-area gold stamping is easy to generate patterns, or paper deformation is caused due to uneven padding, especially laser foil is stamped, or the laser foil and the laser paper are operated, so that the hot stamping difficulty is higher.
Disclosure of Invention
Aiming at the problems, the invention provides a product which is fast and convenient to produce and low in production cost and adopts a fine casting embossing film for embossing and hot stamping and a production process thereof.

2) And under the condition that the fine casting transfer gloss oil on the paper is not dried, adhering a fine casting embossing film to the surface of the fine casting transfer gloss oil, applying a certain pressure, transferring the grains on the fine casting embossing film to the surface of the fine casting transfer gloss oil, drying the fine casting transfer gloss oil by using a UV curing light source, and stripping the fine casting embossing film from the UV curing dried gloss oil to obtain the UV curing fine casting transfer gloss oil with the grains.
3) And then carrying out metal foil transfer on the UV-cured fine casting transfer varnish, carrying out heating and stamping on the metal foil and the UV-cured fine casting transfer varnish through a heating and stamping roller, transferring the metal layer on the metal foil to the surface of the UV-cured fine casting transfer varnish with grains, and finishing fine casting embossing.
And the step 3 is summarized, namely screen printing fine casting transfer gloss oil → UV curing + fine casting embossing transfer → carrying out heat transfer gold stamping on the fine casting transfer gloss oil with the pattern.
The method comprises the steps of carrying out fine embossing casting on the surface of paper, and then carrying out heat transfer gold stamping on the surface of the cast texture.
The fine casting transfer gloss oil is transparent gloss oil, and in the fine embossing casting process, a UV light source penetrates through the fine casting embossing film, so that the gloss oil can be fully dried, and the gloss oil has good adhesive force; the gloss oil is soft and has better folding resistance, and information on the film can be completely transferred to the gloss oil; the dried varnish is heated (60-120 ℃) to be slightly softened, and the metal layer on the metal foil can be transferred to the surface of the dried varnish.
The proportion of the fine casting transfer gloss oil is different from that of the existing printing ink, and the requirements of a printing process are met by continuously adjusting the raw materials and the proportion in the printing process, and the fine casting transfer gloss oil is prepared from the following raw materials in parts by weight: 40-45 parts of acrylic resin, 15-20 parts of acrylate copolymer, 10-15 parts of methacrylic acid-beta-hydroxyethyl ester, 10-15 parts of isobornyl acrylate, 10-15 parts of tripropylene glycol diacrylate, 3-5 parts of photoinitiator and 2-5 parts of auxiliary agent.
Under the condition that the fine casting transfer varnish is not dried, a fine embossing film is attached to the surface of the varnish, a certain pressure is applied, the varnish is solidified while being pressurized, then the fine embossing film is stripped from the surface of the solidified varnish, finally, the grain information is completely kept on the solidified casting transfer varnish, and the pressure is generally applied by a pressing wheel, so that the pressure is not too high.
Further, the fine casting embossed film in the step 2) is a transparent film through which UV light penetrates, and the film thickness is 0.09-0.15 mm.
The embossing surface of the fine casting embossing film can not be back-coated in the process of attaching and impressing the fine casting embossing film, so that incomplete transfer information caused by reaction with undried gloss oil is avoided; the fine cast embossed film can be reused.
The fine casting embossed film is generally formed by heating a film material (generally a high polymer material such as PET/OPP) in a hot pressing mode, and then shaping the lines on an embossed steel roller on the film material in a stamping mode.
Further, the heating temperature for heating the embossing roller in the step 3) is 60-120 ℃.
The fine casting embossing hot stamping product manufactured by using fine casting embossing hot stamping comprises paper, wherein the paper is stamped with fine casting transfer gloss oil with grains after UV curing, and a metal layer is hot-transferred and hot-stamped on the fine casting transfer gloss oil after UV curing.

The invention has the beneficial effects that:
1. the adopted silk screen plate can be manufactured by a printing enterprise, the plate making time is short and can be finished within 1 hour generally, and the adopted fine casting film can be used for preparing a common film in advance; the system can meet the requirement of rapid proofing, gives rapid feedback, can respond to the market in time, and has stronger autonomy to printing enterprises.
2. The cost is lower than that of the traditional embossing thermoprinting, and because the process innovatively adopts a method of hot embossing transfer and film press casting, a gold stamping plate is not needed in the embossing thermoprinting process; the adopted silk screen plate can be manufactured by a printing enterprise, a plate (such as a silk screen plate with partial snowflakes) can be adopted together with silk screen plates of other procedures, the fine casting embossed film is about 20 yuan/m, 8000 yuan is required for a film roll with 500m, width and width of 800cm, the film roll can be repeatedly used, the price of casting transfer ink is about 240 yuan/kg, and the calculated using amount of the one-time proofing ink is not more than 100 yuan.
3. The method comprises the steps of manufacturing a fine pattern film, firstly pressing lines on the surface of gloss oil in a mould pressing mode, and then transferring a metal layer on an electrochemical aluminum foil to a position with lines and needing gold stamping through heat transfer; no matter the common foil or the laser foil is scalded, the problem of high difficulty in plate making and padding operation is directly solved because a bronzing plate is not adopted. The mould pressing and gold stamping position is controlled by printing, can be applied locally or in full edition, has high maneuverability, and solves the problem of positioning and registration fluctuation of the alumite; excessive temperature and pressure are not needed in the casting process, paper is not easy to deform, and certain guarantee effect is achieved on the processing stability of the subsequent procedure.
