Inkjet printers have a variety of surface treatment methods after printing, and new technologies and new materials emerge one after another. However, the main methods commonly used in the surface treatment of ink jet printers are laminating, laminating, cold laminating, and laminating.
1, Lamination
Laminating film is a kind of treatment method that applies a special liquid evenly on the surface of the printed paper and then cures it. It is operated by a specialized laminating machine. The characteristics of the lamination film are:
A, good quality laminating adhesive fastness, no blistering, good sealing performance, the surface is like a mirror.
B. The low cost is the cheapest surface treatment cost for printed paper, and even less than one yuan per square meter.
C. Simple operation After laminating, there is no post work, no side strips, no cutting work, and a lot of labor is saved, which is the preferred equipment for mass production.
D. High prices also require special venues for laminating machines. There are many types of machines, but all of them are expensive and bulky. They need to be set up separately.
2, cold heading
Cold laminating is a kind of processing method that sticks a glue film on the back to the surface of the printed paper, generally by means of a cold heading machine. Its characteristics are:
A. The speed is the fastest way for the surface treatment of printed paper.
B. The paper after adaptability and strong printing is wide, narrow, long, and short.
C, can provide a variety of surface effects Cold laminating film variety is rich and varied, in addition to high light and matte, what matte, laser, gold powder, etc., can make the paper surface after processing more diversified.
D. The equipment is simple and cheap The cold heading machine is cheap and does not use electricity during use.
E. After all, the quality is generally glued, so the quality of cold heading is general. In particular, if the paper is curled and then unfolded after cold lamination, bubbles and wrinkles may appear. One-sided cold heading also tends to curl the paper.
F, easy aging, shrinkage, not long-term preservation and not to mention the quality of the cold laminating film itself, even if the current market is relatively good quality cold laminating film also has aging, shrinkage problems, is not conducive to long-term preservation, so I want The long-term preservation of the photos can not be used in the cold way.
3, plastic seal
Plastic seal is to use a kind of double-layer soft film to sandwich the printed paper, and then heat it through the laminator to bond the film around and form a treatment method to seal the paper. Plastic seals have the following features:
A. The equipment is simple and cheap. Currently, it is less than A3 format and the price is cheap.
B. Simple operation With only a few switches and a temperature knob, the operation is simple.
C. A multi-purpose laminator can be used for laminating and can be used for laminating and even laminating cards and peritoneum.
D. After the plastic film is sealed, the film is hardened and becomes brittle so that it cannot be curled. The work forms a hard plate, which makes it useful in the production of badges, hanging cards, etc. It is also commonly used in small photographs later in the year. A major method of processing.
E, the quality is generally limited by the plastic film, the plastic quality is generally. After the plastic film is heated, it adheres to the surface of the paper, but it is not close, that is to say, the plastic film and the paper cannot be completely glued together. After a certain period of time, the plastic bag may enter the air, so the plastic cover plays a decorative role. The protection is also general.
F, easy to aging plastic film hardened after heating, can not be folded and can not be curled so it is not suitable for large-format, plastic film is also subject to temperature changes, too cold to be fragile.
4, hot film
The film on the right can be understood as the post-processing technology of paper-plastic ones, including plastic and cold laminating. The film in the narrow sense refers to a thermal laminator.
Thermal laminating machine can be divided into two types: the instant coating type laminating machine and the precoat type laminating machine. The coating type laminating machine includes three parts: sizing, drying, and hot pressing. The application scope thereof is wide, and the processing performance is stable and reliable. It is a film coating apparatus widely used in China at present. The coating type laminating machine is mainly used for large-scale continuous production in the factory, and the size of the machine is also large. The precoat type laminating machine has no glue and dry part, small size, low cost, and flexible and convenient operation. It is not only suitable for the lamination processing of large-volume prints, but also applicable to the processing of small-lot, scattered prints such as automated desktop office systems. The machine is small in size and can be used on the desktop. In addition to the peritoneum, the precoat laminator can also be used for cold meters. The laminator mentioned later in this article refers to the use of such a thermal coating of the precoating film. Film machine.
This type of thermal laminator uses a film pre-applied with a layer of a similar hot melt and is fully bonded to the surface of the paper by a high temperature and a certain pressure. The film used is called a thermal film and the equipment used is called a thermal film or thermal film. machine. Hot film machines can also be used for cold laminating, so it is also called laminating machine. Hot film is generally double-sided, that is, the front and back of the paper must be covered with film, nothing more than when the film is the front and back of the paper is completed once.
The difference between thermal film and plastic film is mainly the difference of the film. The plastic film is mainly the edge of the seal. The surface of the film and the paper is not completely affixed, and it is sealed. Therefore, the plastic film is in the form of a single double sheet. The plastic film is sandwiched between the two layers of the film. The film used in the film is thinner and softer, relying on the intimate combination with the paper surface and packaged in a roll. The characteristics of hot film are mainly reflected in:
A. The high quality hot film is completely integrated with the paper, without the entry of air, and it is double-coated so that the paper will not be deformed due to shrinkage of the film, basically eliminating the phenomenon of wrinkles, bubbles, detachment, etc. Better.
B. Low cost Even if the double-sided film is cheaper than the one-sided cold film, the thermal film is not as stiff as the plastic film. The paper is flexible and can be curled.
C, can provide a variety of surface effects to increase the appearance of the hot film in addition to the film, high-gloss film, there are some surface with a variety of special effects of decorative film, increase the appearance of hot film.
D. Use more widely After the thermal film, there is a layer of film on both sides of the paper. The paper has better flexibility. The corners are less likely to be torn. It is often used to look at pictures, albums, recipes, etc. The best film treatment
E. Simple operation The low rate of hot film machine has the functions of pause, temperature regulation and speed adjustment. It is relatively simple to operate, and it adopts the package precoating film, which has continuous operation, high production efficiency, and low reject rate in the film.
F, retroperitoneal treatment appears to be troublesome. After the film is coated, the excess thermal film left behind by the paper needs to be manually removed. The workload is large and appears to be troublesome.
G, not suitable for small operation of the film machine start and shut down time is slow, if only a few or a small amount of film is too much delay time, because the film machine requires about 20 minutes to start warming up, cooling before closing is also needs time.
