Description
Technical Field
The invention belongs to the field of package printing, and relates to an online gravure printing method of a reverse glazing process.
Background
The reverse glazing process can achieve the effects of high-brightness light and non-high-brightness light (including traditional matte, frosted, snowflake-like and the like) on the same printed matter, so that the surface of the printed matter forms stronger contrast, the printed matter can present stronger visual impact feeling, and the appearance grade of the packaged printed matter is improved.
However, the reverse glazing process on the surface of the printed matter can only be realized by a single-sheet offset printing mode all the time, a precedent of realizing the reverse glazing process by an online intaglio printing mode is not provided, and how to combine the reverse glazing process with the intaglio printing process or even the high-speed online intaglio printing process and realize the printing speed of more than 160 m/min is a technical problem in the industry.
Disclosure of Invention
The prior art at present has the following defects:
1. the efficiency is low. At present, the reverse glazing process only can be realized by an offset printing mode, the printing speed is low and can only reach about 60 m/min, and the process cannot be suitable for the large-batch continuous production of products.
2. The production process is long in period and high in cost. The reverse glazing process which can be realized only by an offset printing mode at present cannot realize the requirement of online synchronous production, and a printing process is required to be carried out firstly and then a subsequent process is required to be carried out independently. And each procedure is independently produced, and the on-line integrated forming production cannot be realized.
3. The surface finishing effect has low individuation degree. The reverse glazing process which can only be realized by an offset printing mode at present is limited to the limitation of an offset glazing unit, and the ink layer is thin, so that the surface finishing effect with high touch cannot be achieved.
In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide an on-line gravure printing method of reverse glazing process, which can convert the technical means that can only be realized on offset printing to on-line gravure printing, and realize high-speed production, thereby greatly improving the production efficiency of printed products, and improving the surface finishing effect and grade of gravure printed products.
To achieve the above and related objects, the present invention provides an inline gravure printing method of a reverse glazing process, comprising the steps of:
1) Printing base oil: transferring the base oil to a non-highlight area of a substrate layer of the sample for curing;
2) Printing surface oil: the top coat was transferred to the full area on the substrate layer of the sample and cured.
After continuous linkage printing is carried out by using web on-line gravure printing in the two steps, the reverse base oil and the reverse surface oil on the non-bright part generate strong cohesive reaction due to different surface tensions to form granular ink dots, so that the surface of an ink layer is uneven, and the light diffuse reflection non-bright effect is finally realized. And only one layer of reverse surface oil area is printed, so that the light is normally refracted to form a bright effect. The grade and effect of the printed matter are improved by the contrast between the bright part and the non-high bright part.
Preferably, the base oil comprises, in weight percent,
preferably, the surface oil comprises, in weight percent,
in the base oil, epoxy resin and polyurethane resin are used as connecting materials, trimethylolpropane triacrylate, 1,6-hexanediol diacrylate and tripropylene glycol diacrylate are used as diluents, polymers of 2-benzyl-2-dimethylamino-1- (4-morpholinylphenyl) -1-butanone and benzophenone derivatives are used as photoinitiators, polyethylene wax is wax powder, polydimethylsiloxane is used as an auxiliary agent, and the purity of the rest components is 100% except that the purity of polydimethylsiloxane is 99.5%.
In the surface oil, epoxy resin and polyurethane resin are used as connecting materials, trimethylolpropane triacrylate, 1,6-hexanediol diacrylate and tripropylene glycol diacrylate are used as diluents, polymers of 2-benzyl-2-dimethylamino-1- (4-morpholinyl phenyl) -1-butanone and benzophenone derivatives are used as photoinitiators, and the purity of the components is 100%.
The photoinitiator, also called photosensitizer or light curing agent, is a compound which can absorb energy with certain wavelength in an ultraviolet region (250-420 nm) to generate free radicals, cations and the like so as to initiate the polymerization, crosslinking and curing of monomers. In the light curing system, including UV glue, UV coating, UV ink and the like, the UV glue, the UV coating, the UV ink and the like undergo chemical changes after receiving or absorbing external energy and are decomposed into free radicals or cations, so that the polymerization reaction is initiated. All substances which, upon irradiation with light, generate free radicals and initiate further polymerization are generally referred to as photoinitiators.
The vehicle is an important component of the printing ink and is the fluid portion of the ink. Typically the bulk resin of the ink. The rheology, viscosity, drying, film formation and printing properties of the printing inks depend mainly on the binder. The solid components in the ink can be ground in the manufacturing process by the wetting action of the binder, the transfer in the printing process is completed by the viscosity of the binder, and the pigment is protected by drying and film-forming property of the binder on a printed matter to form an ink film with gloss fastness on a print.
The auxiliary agent plays a role in adjusting the overall performance of the ink, and is not resin generally, but other non-resin components capable of adjusting the rheological property, viscosity, drying property, film forming property and printing performance of the ink.
Preferably, in step 1), the performance parameters of the base oil are as follows: the viscosity of the base oil is 8-25s; the glossiness of 60 degrees is 40-80%; the friction resistance is more than or equal to 85 percent.
The viscosity unit of the invention is s, the viscosity of the No. 4 cup of the YinYun cup is used as a standard, the YinYun cup is also called a viscosity cup, the viscosity is expressed by the flow speed of liquid, the YinYun cup generally has No. 2-7 YinYun cup, and the YinYun cup has the advantages of convenient use, simple measuring procedure, test time saving, accuracy, high speed, easy cleaning and the like. The viscosity measurement device is widely applied to viscosity measurement before or during use of printing ink in printing industries such as intaglio printing, relief printing, lithographic printing, flexographic printing, silk screen printing and the like, and mainly aims to keep the viscosity of the printing ink stable in the printing process, so that the viscosity of the printing ink does not exceed a set range all the time, and the color mixing value of the printing effect is guaranteed.
Gloss is a physical quantity that evaluates the ability of a material surface to reflect light under a set of geometrically specified conditions. It therefore states a reflective property with directional selectivity. Gloss can be classified into several categories according to its characteristics, and we generally say gloss is referred to as "specular gloss". Gloss is measured using a gloss meter, and most gloss meters measure the reflectance of the surface of an object, i.e., are known as specular gloss meters. The angle of incidence selected during measurement is different, and the measured result is also different. The larger the angle of incidence, the larger the specular reflectance and the higher the gloss. The experimental gloss 60 represents the selected angle of incidence of 60.
Preferably, in the step 2), the performance parameters of the surface oil are as follows: the viscosity of the surface oil is 8-20s; the glossiness of 60 degrees is more than or equal to 70 percent; the friction resistance is more than or equal to 85 percent.
The surface effect is influenced by the engraving parameters of the printing plate, and the hand feeling is smoother due to the thick bottom ink layer and the thin backlight effect of the surface ink layer which are more compact in general; the back light effect of the thin bottom ink layer and the thick surface ink layer is more rough and scattered, the hand feeling is stronger, and therefore the back light can be converted into the following printing plate engraving parameters:
in the step 1), the printing parameters of the base oil are as follows: when the engraving process is laser corrosion, the number of the screen lines is 58-62l/cm; the shape of the mesh opening: a hexagon; depth of the mesh point: 33-37 μm, and under the printing parameters, the ink feeding amount is large, the ink layer is thick, and the effect is finest;
preferably, in step 1), the printing parameters of the base oil are as follows: when the engraving process is laser corrosion, the number of the screen lines is 68-72l/cm; the shape of the net holes: a hexagon; depth of the mesh point: 20-24 μm;
preferably, in step 1), the printing parameters of the base oil are as follows: when the engraving process is laser corrosion, the number of the screen lines is 78-82l/cm; the shape of the mesh opening: a quadrilateral; depth of the mesh hole: 18-22 μm;
preferably, in step 1), the printing parameters of the base oil are as follows: when the engraving process is laser corrosion, the number of the screen lines is 88-92l/cm; the shape of the mesh opening: a quadrilateral; depth of the mesh hole: 13-17 μm;
preferably, in step 1), the printing parameters of the base oil are as follows: when the carving process is electronic carving, the number of the screen wires is 93-97l/cm; the shape of the net holes: a rhombus shape; depth of the mesh point: 18-22 μm, and under the printing parameters, the ink feeding amount is small, the ink layer is thin, and the effect is the coarsest.
Preferably, in step 1), the printing parameters of the top oil are as follows: when the engraving process is laser corrosion, the number of the screen lines is 58-62l/cm; the shape of the mesh opening: a hexagon; depth of the mesh point: 33-37 μm, and under the printing parameters, the ink feeding amount is large, the ink layer thickness is thick, and the effect is the coarsest.
Preferably, in step 1), when the engraving process is electronic engraving; the number of the screened lines is 58-62l/cm; the shape of the mesh opening: a rhombus shape; depth of the mesh point: 52-57 mu m;
preferably, in step 1), the printing parameters of the top oil are as follows: the printing parameters of the surface oil are as follows: when the engraving process is electronic engraving; the number of the screened lines is 68-72l/cm; the shape of the mesh opening: a rhombus shape; depth of the mesh hole: 43-47 μm;
preferably, in step 1), the printing parameters of the top oil are as follows: when the engraving process is electronic engraving; the number of the screened lines is 78-82l/cm; the shape of the mesh opening: a rhombus shape; depth of the mesh point: 33-37 μm;
preferably, in step 1), the printing parameters of the top oil are as follows: when the engraving process is electronic engraving; the number of the screened lines is 93-97l/cm; the shape of the mesh opening: a rhombus shape; depth of the mesh point: 18-22 μm, and under the printing parameters, the ink feeding amount is small, the ink layer is thin, and the overall effect is finest.
The ink quantity of the network holes of the laser etching process is far larger than that of the electronic engraving process.
The ink transfer amount of the reverse polishing base oil and the reverse polishing surface oil can be influenced by the change of the printing speed and the viscosity of the ink in the circulating state. Generally, faster printing speeds require lower ink viscosities to enhance the inking and transfer of the ink in the printing mechanism. However, lower ink viscosity results in lower ink solids and thinner ink layer thickness.
The general printing speed and the circulating viscosity of the reverse glazing ink (base oil and surface oil) have the following matching relationship: printing speed: 100 m/min; viscosity of the base oil: 25 +/-3 s; viscosity of the face oil: 22 +/-3 s;
preferably, the printing speed: 95-105 m/min; viscosity of the base oil: 22-28s; viscosity of the face oil: 19-25s;
preferably, the printing speed: 115-125 m/min; viscosity of the base oil: 17-23s; viscosity of the face oil: 15-21s;
preferably, the printing speed: 135-145 m/min; viscosity of the base oil: 12-18s; viscosity of the face oil: 10-16s;
preferably, the printing speed: 155-165 m/min; viscosity of the base oil: 9-15s; viscosity of the face oil: 6-12s;
preferably, the printing speed: 165-175 m/min; viscosity of the base oil: 8-14s; viscosity of the face oil: 5-11s.
Because the reverse glazing primer has a certain proportion of wax powder, the wax powder proportion of the primer in the ink cylinder is continuously increased because the wax powder transfer amount is less than the resin transfer amount after continuously printing for 24 hours. Therefore, the ink viscosity needs to be measured regularly (not more than 60 minutes) to ensure stable state.
As described above, the present invention has the following advantageous effects:
1) The production efficiency is high. The printing speed can reach more than 160 m/min at most by adopting an online gravure printing mode, so that the production efficiency of printing is greatly improved.
2) The production process has short period and low cost. The on-line gravure integrated production is adopted, the on-line gravure integrated production can be linked with various other printing and post-printing devices of the on-line gravure, the product can be integrated after printing, the production process and the production period are shortened, the printing speed of the invention of more than 160 m/min is 2-3 times of the production efficiency of the original traditional reverse glazing process, the production efficiency of related high-grade printed products can be greatly improved, and the labor cost is saved.
3) Realizing the personalized surface effect. The matching between the reverse glazing ink and the gravure engraving parameters can realize different non-bright effects such as matte, frosted and snowflake imitation, improve the surface finishing effect and grade of mass-produced printed products in a gravure mode, even can partially replace the traditional screen printing process, and improve the personalized process level.
