Abstract
The invention discloses a process for improving gold stamping effect by increasing gravure printing base oil, which comprises the steps of additionally installing one or more groups of gravure printing plates by utilizing the existing multicolor overprinting gravure unit, additionally printing a gold stamping ink at a trademark gold stamping position, drying in a dryer, and then sending a printed matter to a hot stamping machine for gold stamping; the gold stamping ink comprises the following components in percentage by weight: polyethylene wax: ethyl acetate: 76-82% of ethanol: 2-4: 4-6: 0.5 to 1.5. The invention provides a process for improving the gold stamping effect by adding gravure printing base oil, which can eliminate the defect of dot dropping of an electrochemical aluminum foil gold stamping product, has good hot stamping effect and high product qualification rate, saves the working hours of subsequent inspection and improves the gold stamping effect.
Description
Technical Field
The invention belongs to the technical field of gold stamping processes, and particularly relates to a process for improving a gold stamping effect by adding gravure printing base oil.
Background
The gold stamping process of the trademark is generally carried out after the printing process, and the trademark enters a gold stamping machine for electrochemical aluminum foil hot stamping after being overprinted with multiple colors by a gravure printing unit. At present, the processing technology of the brand hot stamping position in the printing procedure has two kinds, one is that the hot stamping position is the gravure printing plate hollow out bottom paper printing; the other is that the hot stamping position is gravure printing plate without hollow printing, and the common gravure ink or finishing oil is adopted for printing. The hot stamping on the hollowed-out base paper can cause the hot stamping of the electrochemical aluminum foil to have points and defects due to uneven coating or convex-concave unevenness of the printing surface of the base paper, and the product quality requirement cannot be met; the common gravure ink or overprint varnish is adopted for hot stamping, so that the reverse drawing of a gravure ink layer causes the simultaneous scarcity of the alumite and the ink due to the processing technologies of heating hot stamping of the alumite, peeling of a base film and the like, and the subsequent inspection working hour is increased. Therefore, a process for improving the gold stamping effect by increasing the gravure printing base oil, which can eliminate the defect and defect of the electrochemical aluminum foil gold stamping product, has good hot stamping effect and high product qualification rate, saves the subsequent inspection working hours, needs to be developed.
Disclosure of Invention
The invention aims to provide a process for improving the gold stamping effect by adding gravure printing base oil, which can eliminate the defect of dot dropping of an electrochemical aluminum foil gold stamping product, has good hot stamping effect and high product qualification rate, saves the working hours of subsequent inspection and improves the gold stamping effect.
In order to achieve the purpose, the invention adopts the technical scheme that: the method comprises the following steps of additionally installing one or more groups of gravure printing plates by utilizing the existing multicolor overprinting gravure printing unit, additionally printing one layer of gold stamping oil at a trademark gold stamping position, drying in a dryer, and then sending a printed matter to the hot stamping machine for gold stamping;
the bronzing oil comprises the following components in percentage by weight: polyethylene wax: ethyl acetate: 76-82% of ethanol: 2-4: 4-6: 0.5 to 1.5.
Furthermore, the electric carving pattern of the gravure printing plate is consistent with the gold stamping pattern, and the depth of the printing plate is 18-22 mu m.
Further, the gold stamping ink was diluted to an on-machine viscosity of 17 seconds using n-propyl ester as the dilution solvent.
Further, the drying temperature was 50 ℃.
Further, the printer speed was 120 m/min.
The invention has the beneficial effects that: the production process is characterized in that after the product is subjected to multicolor overprinting and before the gold stamping process, one or more groups of gravure printing plates are additionally arranged by utilizing the existing multicolor overprinting gravure unit, and the medium which is difficult to peel off and can smooth the original paper is additionally printed at the gold stamping position, so that the phenomena of broken points and incomplete products can not occur during gold stamping production, the product percent of pass is improved, excessive inspection working hours of subsequent procedures are reduced, the working efficiency is improved, and the production cost is reduced.
Detailed Description
The present invention is further illustrated by the following examples, which include, but are not limited to, the scope of the present invention.
Example 1
One or more groups of gravure printing plates are additionally arranged by utilizing the existing multicolor overprinting gravure printing unit, the gravure printing plates are electronically engraved, the electrically engraved patterns are consistent with the gold stamping patterns, and the depth of the special printing plates is 18 mu m; the preparation comprises the following components in percentage by weight: polyethylene wax: ethyl acetate: ethanol 76: 2: 4: 0.5 of bronzing ink; diluting the gold stamping ink to the on-machine viscosity of 17 seconds by using n-propyl ester as a diluting solvent; printing one gold stamping ink at the position of the trademark gold stamping, and then drying in a dryer, wherein the drying temperature is controlled to be 50 ℃, and the speed of the printer is controlled to be 120 m/min; and then, the printed matter is sent to a hot stamping machine for hot stamping. The gold stamping product is smooth, flat and firm, and has no defects, dropping points, blotches, bottom exposure and burrs.
Example 2
One or more groups of gravure printing plates are additionally arranged by utilizing the existing multicolor overprinting gravure printing unit, the gravure printing plates are electronically engraved, the electrically engraved patterns are consistent with the gold stamping patterns, and the depth of the special printing plates is 20 mu m; the preparation comprises the following components in percentage by weight: polyethylene wax: ethyl acetate: ethanol ═ 79: 3: 5: 1, gold stamping ink; diluting the gold stamping ink to the on-machine viscosity of 17 seconds by using n-propyl ester as a diluting solvent; printing one gold stamping ink at the position of the trademark gold stamping, and then drying in a dryer, wherein the drying temperature is controlled to be 50 ℃, and the speed of the printer is controlled to be 120 m/min; and then, the printed matter is sent to a hot stamping machine for hot stamping. The gold stamping product is smooth, flat and firm, and has no defects, dropping points, blotches, bottom exposure and burrs.
Example 3
One or more groups of gravure printing plates are additionally arranged by utilizing the existing multicolor overprinting gravure printing unit, the gravure printing plates are electronically engraved, the electrically engraved patterns are consistent with the gold stamping patterns, and the depth of the special printing plates is 20 mu m; the preparation comprises the following components in percentage by weight: polyethylene wax: ethyl acetate: ethanol ═ 82: 4: 6: 1.5 of gold stamping ink; adopting n-propyl ester as a diluting solvent, diluting the gold stamping ink until the viscosity of the gold stamping ink on a machine is 17 seconds, and additionally printing a layer of gold stamping ink at the gold stamping position of the trademark; then drying in a dryer, controlling the drying temperature at 50 ℃ and controlling the speed of the printing machine at 120 m/min; and then the printed matter is sent to a hot stamping machine to carry out gold stamping and gold stamping on the product, and the product is smooth, flat and firm without defects, dropping points, blotches, bottom exposure and burrs.
