Abstract
The invention relates to a printing method whereby a high-gloss coating can be produced on a substrate, which is printed on a precoat with a water-based inkjet ink. Prints with high gloss values are obtained by applying a highly viscous printing medium in the final printing process.
Description
Technical Field
The invention relates to a printing method for producing high-gloss coatings, to the use of a highly viscous printing medium (hochviskosen Druckmedium) in a printing method for controlling the gloss of a coating, and to a printed product obtained by the method according to the invention.
Background
In a printing press, printed products with different optical properties can be produced. For many applications (e.g. in packaging printing), visually appealing prints are desired. There is a particular consumer demand for printed matter that has a shiny appearance, in whole or at least in part.
In the prior art, the production of glossy prints is effected, for example, by varnishing (Lackieren) the desired print image on the printing material with colorless varnish in a varnishing unit of a printing press. However, the results achievable here are partially limited with respect to the gloss produced, in particular if the substrates printed by means of the inkjet printing method, for which the inkjet inks used are water-based, are glossy. Since in water-based inkjet printing processes, regulators (also referred to as precoats) are usually applied to the print substrate before inkjet printing in order to achieve better adhesion of the inkjet ink also to the print substrate (for example paper, cardboard or plastic). However, most commercially available precoats have an acidic pH here, which is known to have a gloss-reducing effect on the finally applied colorless varnish.
Document DE 102017213226 a1 describes a method for producing printed matter, in which a Precoat (Precoat) having an acidic pH is varnished with the aid of a water-based varnish. This approach should reduce the undesirable difference in gloss on the print.
Here, a printing method is required that: by means of these printing methods, printing materials having high gloss values can be produced, wherein for these printing materials, printing has been carried out on a precoat in a water-based inkjet printing. It should also be possible to realize that not only the full surface is covered
But also only in certain limited areas of the print substrate.
It has now been found that: high gloss coatings can be obtained on the substrate, which have been printed onto the precoat in ink jet printing by means of water-based ink jet inks by printing highly viscous printing media onto the dried water-based ink jet inks.
Disclosure of Invention
The reason for the particularly high gloss resulting from the method according to the invention may be that, owing to the highly viscous nature of the print medium, no or only a small influence on the basic layer (in particular the precoat) is achieved in the method according to the invention. It can happen that such highly viscous printing media, due to the usually low solvent content in the method according to the invention, do not react or react only to a slight extent with the base layer, in particular the precoat layer. It can therefore happen that the gloss layer does not react or reacts only slightly with the gloss-reducing acid of the precoat layer.
With the method according to the invention, it is possible to provide the printing material with a high-gloss coating. It is also possible to produce high gloss only at certain points of the print substrate, for example in the form of geometric figures, patterns, text and the like.
Accordingly, the present invention relates to a printing method comprising the steps of:
i) providing a printing material;
ii) applying a conditioning agent to the substrate;
iii) drying the conditioning agent on the substrate;
iv) printing a water-based inkjet ink onto the dried conditioner by means of inkjet printing;
v) drying the water-based inkjet ink on the substrate;
vi) printing a high viscosity printing medium onto the dried water-based inkjet ink; and
vii) drying the printed high-viscosity printing medium on the substrate.
In step i) of the method according to the invention, a printing material is provided. In principle, all types of materials which can be processed in a printing press are suitable as printing materials. Suitable substrate materials are preferably selected from: paper, cardboard and plastic. The printing material is preferably in the form of a sheet, a web or in the form of an object (for example a sphere).
In step ii) of the method according to the invention, the conditioning agent is applied to the printing material. Such application can be effected according to methods known in principle in the prior art, for example by spraying, wiping or printing, wherein inkjet printing and flexographic printing are preferred among the printing methods. Particularly preferably, the application in step ii) is effected by means of flexographic printing. The modulator (kondiionimirtetel) is preferably selected from: precoating (precoatat), also known as Primer (Primer), for water-based inkjet inks. Regulators (e.g. precoats) are known in principle to the person skilled in the art and are generally used to improve the adhesion of the printed highly viscous printing medium to the print substrate and to achieve better printed images on the print substrate. In a preferred embodiment of the process according to the invention, the regulator has an acidic pH, i.e. a pH of less than 7.
In step iii) of the method according to the invention, the conditioning agent on the printing material is dried. Methods for drying a conditioning agent, preferably a precoat, on a printing substrate in a printing press are known in principle to the person skilled in the art. Such a drying method preferably comprises: the printing material provided with the conditioning agent is subjected to radiation (in particular infrared radiation) and/or hot air by means of one or more radiation dryers (for example LED dryers) and/or one or more hot air dryers.
In step iv) of the process according to the invention, a water-based inkjet ink is printed onto the dried conditioner by means of inkjet printing. Water-based inkjet inks are known in principle to the person skilled in the art, these being essentially drying by removing the water contained in the ink. In contrast to water-based inkjet inks, uv inkjet inks effect drying under the action of uv radiation or electron radiation, if necessary with one or more photoinitiators (photoinitiators). In step iv), all types of inkjet printing methods can in principle be used. These printing methods are known in principle to the person skilled in the art. For these printing methods, the inkjet ink is usually applied to the substrate by means of one or more inkjet print heads (which have a plurality of printing nozzles).
In step v) of the method according to the invention, the water-based inkjet ink on the substrate is dried. As a drying method, the drying method mentioned as preferred for step iii) is preferred here.
In step vi) of the method according to the invention, a highly viscous printing medium is printed onto the dried water-based inkjet ink.
Detailed Description
In a preferred embodiment, the highly viscous printing medium has a viscosity in the range from 40 to 400 pas, particularly preferably in the range from 50 to 300 pas, measured with the aid of a cone-plate viscometer (Kegel-plate-Viskosimeter) at 20 ℃.
In another preferred embodimentIn one form, the highly viscous printing medium is non-aqueous
This means that: such highly viscous printing media have a water content of less than 10% by weight, preferably less than 5% by weight and particularly preferably less than 2% by weight, with reference to the overall highly viscous printing medium.
In a further preferred embodiment, the highly viscous printing medium is aqueous
This means that: such highly viscous printing media have a water content of at least 10% by weight, preferably at least 30% by weight and particularly preferably at least 40% by weight, with reference to the overall highly viscous printing medium. In this embodiment, the highly viscous printing medium preferably has a high solids content, wherein the solids content of the highly viscous printing medium is preferably at least 20% by weight, particularly preferably at least 30% by weight, based on the overall highly viscous printing medium. Despite the high water content, the printing medium in this embodiment still has the property of being highly viscous due to the high solids content.
In another preferred embodiment, the highly viscous printing medium is selected from the group consisting of: oil-based print media and ultraviolet print media. Oil-based printing media are known in principle to the person skilled in the art, which have one or more nonpolar organic compounds as solvents, which are completely or partially removed on drying and thus contribute to the drying of the oil-based printing media. Uv printing media are known in principle to the person skilled in the art, these uv printing media generally comprising one or more monomers or oligomers (oligomeres) which are dried essentially by crosslinking (Vernetzung) under the action of electron radiation or uv radiation, if necessary with one or more photoinitiators. Preferred uv printing media are selected from uv inkjet inks.
In a further preferred embodiment of the method according to the invention, the highly viscous printing medium is substantially colorless. Thereby, a transparent, high gloss coating is obtained on the produced print, below which coating the printed image of the water-based inkjet ink is visible to the naked eye. It is also possible that such a highly viscous printing medium is mixed with one or more colorants, for example one or more pigments.
In a further preferred embodiment, the highly viscous printing medium is lithographically printable
This means that: such highly viscous printing media can be processed in a printing press and are suitable for use in a printing process as follows: by means of these printing methods, non-full-surface printed images, such as geometric figures, patterns, text and the like, can be printed on the printing material. In contrast to print media that are capable of lithographic printing, print media that are not capable of lithographic printing are generally only suitable for full-surface application onto a substrate.
As printing methods in step vi), in principle all such printing methods are suitable: by means of these printing methods, highly viscous printing media (in particular as mentioned above as preferred) can be printed on a print substrate in a printing press. A preferred printing method is a printing method of: for these printing methods, the application of the printing medium to the substrate is effected indirectly. Particularly preferred printing methods are selected from: offset printing methods, relief printing methods, and flexographic printing methods. A very particularly preferred printing process is selected from the group of indirect relief printing processes (inderekten Hochdruckverfahren). In these printing processes known in principle, in particular as mentioned above, the configuration of the printing press can be changed (if appropriate by suitable means) by the person skilled in the art in order to process and print highly viscous print media. For example, it may be necessary to adapt the printing medium supply in a flexographic printing unit in order to be able to handle highly viscous printing media. It is also possible to use different variants of offset printing, for example the use of a structured rubber blanket.
The subject matter of the present invention is also a printed matter which is obtained by the method according to the invention according to steps i) to vii).
It is also possible to provide a printing material having a two-layer structure, wherein the two-layer structure has a first layer comprising at least one dried conditioner and a second layer comprising at least one dried water-based inkjet ink, wherein the first layer is in contact with the second layer; and printing and drying the above-mentioned highly viscous printing medium on this substrate.
The subject of the invention is therefore also a printing process comprising the following steps:

b) printing a highly viscous printing medium onto the dried water-based inkjet ink; and
c) the highly viscous printing medium printed on the printing material is dried.
In step a), the printing material mentioned for step i), the conditioning agent mentioned for step ii), and the water-based inkjet ink mentioned for step iv) are preferred. In step b), the highly viscous printing media and printing methods mentioned for step vi) are preferred. In step c), the drying methods mentioned for step vii) are preferred.
In a preferred embodiment, in step b), the highly viscous printing medium is non-aqueous. This means that: such highly viscous printing media have a water content of less than 10% by weight, preferably less than 5% by weight and particularly preferably less than 2% by weight, with reference to the overall highly viscous printing medium.
In a further preferred embodiment, in step b), the highly viscous printing medium is aqueous. This means that: such highly viscous printing media have a water content of at least 10% by weight, preferably at least 30% by weight and particularly preferably at least 40% by weight, with reference to the overall highly viscous printing medium. In this embodiment, the highly viscous printing medium preferably has a high solids content, wherein the solids content of the highly viscous printing medium is preferably at least 20% by weight, particularly preferably at least 30% by weight, based on the overall highly viscous printing medium. Despite the high water content, the printing medium in this embodiment still has the property of high viscosity due to the high solids content.
In another preferred embodiment, the highly viscous printing medium in step b) is selected from the group consisting of: oil-based print media and ultraviolet print media. Preferably, the printing method for printing such a highly viscous printing medium in step b) is selected from: offset printing methods, relief printing methods, and flexographic printing methods. Particularly preferably, the printing method for printing such a highly viscous printing medium in step b) is selected from: indirect relief printing methods.
The subject of the invention is also the use of a highly viscous printing medium in a printing process for controlling the gloss of a coating of a dried water-based inkjet ink.
With the method according to the invention, it is possible to produce prints having high gloss values in a printing press. In this case, Gloss Points (GP) of greater than 60 or greater than 70 can generally be achieved. In contrast, in the methods known from the prior art for producing glossy coatings in printing presses, generally only Gloss Points (GP) of less than 60 are achieved. Furthermore, not only full-surface application but also the generation of gloss in only individual regions of the print substrate can be achieved in a simple manner by means of the method according to the invention, for example by means of offset lithography.
