Description
Technical Field
The invention relates to the technical field of printing, in particular to a printing process for pictures and texts with stereoscopic impression.
Background
In order to make printed products, such as packaging boxes, more aesthetically pleasing, it is common to print using a number of different types of printing processes. For example, an order form of a cigarette packaging box received by the applicant needs to form a picture and text with three-dimensional effect on the surface of the order form, and the currently adopted printing process comprises seven steps, wherein the steps are as follows: 1. offset printing, printing picture and text and ground color; 2. carrying out first gold stamping, namely stamping a frame of a pattern by using gold alumite; 3. performing second gold stamping, namely performing hot stamping on characters by using red alumite; 4. carrying out first silk-screen printing, carrying out silk-screen printing on a matte oil layer, and covering other places except for the pictures and texts on the printing surface; 5. printing the raised ink on the image-text (printing the raised ink locally) by a second silk screen printing process to ensure that the surface of the image-text is glossy; 6. embossing, namely embossing the area where the pictures and texts are located (so that the area where the plane pictures and texts are located is raised), and the pictures and texts have stereoscopic impression; 7. and die cutting, namely performing die cutting according to the shape and size requirements of the product, and removing redundant parts to obtain a finished printed product.
According to the current situation, the procedures of offset printing, first silk-screen printing, second silk-screen printing, embossing, die cutting and the like in the printing process are necessary procedures for forming pictures and texts with stereoscopic impression and surface gloss; the first gold stamping and the second metal stamping can be selected, and the process can be omitted when the product does not need to be stamped with pattern frames and characters.
In the printing process, in order to make the surface of the image-text glossy, the raised ink is printed on the image-text by adopting the second silk-screen printing, so that the difficulty of the process is increased. The printing process needs two silk-screen printing processes, the more the processes are, the lower the overall production efficiency is, the longer the time consumption is, the higher the production cost is, and the larger the carbon emission is. In order to improve the overall production efficiency and reduce the production cost, the applicant repeatedly researches and simplifies the process flow of the printing process on the premise of ensuring that the product meets the requirements, and provides the printing process.
Disclosure of Invention
The technical problem to be solved by the invention is to provide the printing process with the stereoscopic graphics and texts, which simplifies the process flow and is beneficial to reducing the production cost. The technical scheme is as follows:
a printing process with stereoscopic graphics and texts is characterized by comprising the following steps:
(1) offset printing
Printing pictures and texts and ground colors on printing paper by adopting an offset printing process, then coating gloss oil on the printing paper, and forming a gloss oil layer on the offset printing pictures and texts and the ground colors;
(2) screen printing
Silk-screen printing a matte oil layer, wherein the matte oil layer covers other areas except the pictures and texts on the printing surface of the printing paper;
(3) embossing
Embossing the area where the pictures and texts are located to enable the pictures and texts to have stereoscopic impression;
(4) die cutting
And (4) carrying out die cutting according to the shape and size requirements of the product, and removing redundant parts on the printing paper to obtain a finished product of the printed matter.
In the invention, when the matte oil layer is silk-screened in the step (2), the part corresponding to the image-text area on the matte oil layer is hollowed out, the gloss oil layer of the image-text area is not covered by the matte oil layer, and the gloss of the surface of the image-text area is kept; after the area where the pictures and texts are located is embossed (the area where the plane pictures and texts are located is raised) in the step (3), the formed pictures and texts have the same effect as the existing printing process, namely the pictures and texts have stereoscopic impression and glossy surface.
Preferably, the varnish used in the step (1) is UV ink fountain varnish. And (4) coating gloss oil on the full plate, and then carrying out UV curing to form a gloss oil layer.
In a preferable scheme, in the step (1), after the gloss oil is coated on the full plate and the gloss oil layer is formed, the gilt is performed by adopting the electrochemical aluminum, and gilt pictures and texts are formed on the gloss oil layer. The gilding graphics can form part of the graphics in the steps (2) and (3). And (3) when silk-screening the matte oil layer in the step (2), hollowing out the part, corresponding to the gold stamping pictures and texts, of the matte oil layer, so that the gold stamping pictures and texts cannot be covered by the matte oil layer. In a specific scheme, the gold stamping process comprises the following steps: firstly, gold alumite is adopted for carrying out first gold stamping, and a gold stamping pattern frame is formed on the gloss oil layer; then, carrying out secondary gold stamping by adopting red alumite to form gold stamping characters on the gloss oil layer; the gold stamping pattern frame and the gold stamping characters form the gold stamping image-text.
In a preferable scheme, the silk-screen dummy oil layer in the step (2) further has a plurality of dot-shaped hollow areas (such as circular dot-shaped hollow areas); and (3) simultaneously embossing the area where the image and text are located and each point-shaped hollow area. The gloss oil layer of the point-shaped hollow-out area is not covered by the matte oil layer, the surface gloss is kept, and therefore a plurality of glossy convex points are formed after embossing. The size and position of these bumps are generally designed in a desired manner to form part of the final image of the printed article.
Compared with the prior art, the printing process integrates the second-time silk-screen raised printing ink in the prior art into the offset printing, namely, the second-time silk-screen printing is omitted, and the offset printing is fully coated with gloss oil; when the matte oil layer is silk-screened, the part of the pictures and texts needing gloss is hollowed out, so that the surface of the pictures and texts keeps gloss, after embossing, the pictures and texts have stereoscopic impression and have gloss on the surface, and the formed pictures and texts have the same effect as the existing printing process. The printing process of the invention omits a silk-screen printing process, simplifies the process flow, is beneficial to improving the overall production efficiency, reducing the production cost and reducing the carbon emission.
