Self adhesive label printing methods, what is self adhesive label paper

Self-adhesive label printing, also known as self-adhesive printing, trademark printing, is the use of a certain printing method to print the label into a self-adhesive material, the printed finished product can be removed, pasted on the goods or packaging to identify it. So, what are the ways of self-adhesive label printing? What are the characteristics?

The following Huayi label will introduce it to you.

Printing method 1: offset printing.

Offset printing is characterized by fine and rich layers, suitable for large-scale printing, and the printing equipment can be multi-purpose, and domestic self-adhesive printing factories take this as the main printing method. However, the offset printing of sheet-fed paper is not suitable for film, and film labels are mostly roll-to-roll printing, which requires volatile dry ink.

Printing method 2: flexo printing.

Flexo printing is characterized by high production efficiency, advanced technology, and does not pollute the environment. Flexo printing is mainly based on ink and UV ink, using roll-to-roll printing, and the die-cutting method is mainly circular pressing and circular die-cutting.

Printing method three: embossing.

Embossing is characterized by exquisite, economical and stable quality. Embossing is one of the more common printing methods in the Asia-Pacific region. Self-adhesive printing mostly uses resin ink, roll-to-roll printing and sheet-fed printing coexist, and the die-cutting method is flattened.

Printing method four: screen printing.

Screen printing is the most widely adaptable printing method for substrates. Screen printing labels have the characteristics of heavy ink color and strong three-dimensional sense, but the overprinting accuracy is not high, and the equipment can only print a single sheet, which is not suitable for the production of film labels supporting the production line.

At present, the processing method of self-adhesive labels is as follows:

1. Machine fighting. 2. Offset printing.

3. Silk screen printing.

4. Laser laser.

5. Flexographic printing.

Self-adhesive paper is composed of three parts: surface raw material, adhesive, and liner paper. It can be matched or customized according to specific use needs.

Facial paper: According to the material, it is divided into coated paper, PET PVC, etc., and the back of the facial paper is coated with adhesive; Adhesive: The types are permanent adhesive (strong adhesive) type, removable (weak adhesive) type, and readhesive type liner paper

Ordinary liner and glassine liner are coated with a silicone oil layer on the surface, which has a barrier effect on the adhesive.

According to the surface material raw materials, it is divided into paper and film;

1.Paper is divided into: coated paper, glass cardboard, laser paper, kraft paper, fluorescent paper, gold-plated paper, aluminum foil paper, fragile (anti-counterfeiting) paper, silver-plated paper, masking paper, cloth label (Tavik nylon) paper, pearlescent paper, sandwich coated paper, variable information paper.

2.Membranes are divided into: transparent PET translucent PET transparent OPP translucent OPP transparent PVC glossy white PVC matte white PVC synthetic paper glossy gold (silver) polyester matte gold (silver) polyester.

According to the performance of adhesives, they can be divided into two categories:

Permanent adhesives and removable adhesives. According to the needs of use, it can also be divided into general adhesive, adhesive, strong adhesive and special adhesive.

According to the bottom paper, it can be divided into:

White Glassine Paper, Blue Glassine Paper, Yellow Glassine Paper, Kraft Paper, Polyester PET, etc.

Self-adhesive labels, also known as self-adhesive labels, are widely used in liquid detergent products, popular personal care products, glass bottle identification, various trademarks, and logos; The materials of self-adhesive labels are mainly film materials, and medium and high-end daily chemical products, beverage bottles, perfumes, etc. are all used in this kind of material.

Self-adhesive labels usually appear on the surface of the article, such as article instructions, bar codes, **labels, **labels, etc., because the back of the self-adhesive comes with a layer of adhesive, so it is very convenient to take it, more and more stores and shopping malls use self-adhesive labels to change, publicity, etc., so how are self-adhesive labels printed?

The first step of self-adhesive label printing is to typeset according to the content you need, usually with CorelDraw or AI software to make, because the picture produced by this software is a vector drawing, even if it is a very small font printed out very clearly, if it is made with PS software, it will form a pattern, printed will affect its effect, the correctness of the use of software is also the first point to pay attention to in self-adhesive label printing.

After the production software is determined, the size of the size should be considered, because the large number of self-adhesive printing will reduce the cost, but also need to consider the size, then it will involve plate making, because the size of different printing machines is not the same, such as 8k, 4k, 2k, etc., if the size selected is just larger than the fixed size of the printing machine, it is necessary to use a larger size to print, or when it is much smaller than the fixed size of printing, both cases will leave a large number of blanks in the printing process and cause the waste of printing. It is a waste of paper and an extra cost, and when you don't understand it, you can go to a special printing house to consult or let someone else design the plate.

In the design, self-adhesive printing is black and white, some are color, printing is usually called four-color, because the color of the printing process is not the same, in the preparation of the plate, start to produce the film, black and white only need to make a plate, commonly known as film film, printing can be completed once, the cost is relatively much lower, and the four-color self-adhesive label printing is designed in the design, in the film needs to press C, M, Y, K that is, black, red, yellow, blue four primary colors each out of a version, In the printing process also need four times of printing, after the first printing, the other three times are called overprint, need to coincide with the position of the first printing, will print out the color of the design, if the overprint is not good, there will be a lot of ghosting, affecting the visual effect of self-adhesive labels, so four-color printing requires a high printing technology, of course, it is also relatively much higher.

After the printing is completed, it is cut according to the designed size, some are regular round, rectangular, and some are special-shaped self-adhesive labels, at this time, the common shape can be cut directly, if you encounter a special-shaped knife, you need to determine the knife in advance, and then according to the final shape of the printed matter to make the knife before cutting, in the self-adhesive label printing process, the more processes involved, the more expensive it is, but the unique design works can better win the attention of customers, Achieve the effect of publicity.

Self-adhesive label printing is to print the label with the selected method and apply a thin layer of self-adhesive adhesive on its back to make a self-adhesive self-adhesive material. Most with printing equipment, the production of self-adhesive labels.

The self-adhesive label is printed by embossing, and the printing plate is photosensitive resin letterpress, so that the water-based ink or ink suitable for flexographic printing is used for lifting and embedding, and the nature of the ink is changed to adapt to the change of the substrate. Gravure printing adopts a short ink path ink delivery system to supply ink, and web material printing. Gravure printing machine has high speed, long gravure plate-making cycle, and expensive plate-making cost, which is suitable for high-volume label production.

**Fine, rich layers, film labels are mostly roll-to-roll printing, which requires volatile dry ink. Offset printing can print thicker plastic materials, which is suitable for high-volume printing. The machine structure is simple, the cost is low, and the flexo printing adopts water-based ink and ink, which does not pollute the environment.

Screen printing, wide adaptability of substrates, heavy ink color, strong three-dimensional effect, overprint accuracy is not high, not suitable for the production of film labels supporting the production line.

Suitable for ** marking and other retail purposes and other information thermal paper label collapsing ant stick, removable, washable adhesive self-adhesive label. Labels for products with important properties such as water, oil and chemical resistance.

The surface material has PE (polyethylene), PP (polypropylene), PET (polypropylene), etc., peeled off, washed with water, and the product does not leave traces after the self-adhesive label.

Self-adhesive printing of self-adhesive labels is to print the label with the chosen method and apply a thin layer of self-adhesive on its back. Self-adhesive label printing, also known as self-adhesive printing, trademark printing, is the use of a certain printing method to print the label into a self-adhesive material, the printed finished product can be removed, pasted on the goods or packaging to identify it.

Self-adhesive printing featuresThe use of empress printing self-adhesive labels, the printing plate is photosensitive resin letterpress, printing labels have the advantage of full ink, but now the letterpress printing equipment grade is quite different, some are still using circular flat letterpress presses, some use ordinary rotary letterpress presses, and some have used professional oblique back, satellite or unit self-adhesive label printing machines.

The self-adhesive printing machine based on embossing has the ability to print film labels, but it is necessary to contact the best business to replace some related components, such as increasing the tension control system controlled by the servo motor, adding the film surface treatment unit, and the higher-grade machine can also increase the precision registration system. In addition, the power of the UV light source should also be adjusted appropriately.

In recent years, self-adhesive labels can be seen on the product packaging of the daily chemical industry, such as instructions for use of items on bottles, advertising, barcodes on packaging boxes, ** labels, etc., different items due to different packaging styles, the use of self-adhesive labels is also different.

In this way, self-adhesive labels have become an important part of product packaging. But,At present, people's demand for product packaging is getting higher and higher, not only to have a look, but also to personalize the shape of the packaging, so that consumers can feel a different surprise at the moment of opening the package.

Although the label is small, it is necessary to select the suitable label paper and glue according to these conditions. In general, self-adhesive labels need to go through many tests to finally reach consumers. As a label manufacturer, no matter how the future trend develops, if you want to produce high-quality self-adhesive labels, you must pay attention to every detail of label production.

In this regard,Huayi Packaging & Packaging, focusing on the development and production of various self-adhesive labels, whether it is printing color self-adhesive labels, three-proof thermal self-adhesive labels, coated paper labels, wet wipes labels, etc.

The selected method prints the label and coats it with a thin layer of self-adhesive on the back to make a self-adhesive self-adhesive material; Most with printing equipment, the production of self-adhesive labels.

Surface. The surface material is the carrier of the content of the self-adhesive label, and the back of the tissue paper is coated with adhesive. There are many materials that can be used for surface materials, which are generally divided into coated paper, transparent polyvinyl chloride (PVC), electrostatic polyvinyl chloride (PVC), polyester (PET), laser paper, temperature-resistant paper, polypropylene (PP), polycarbonate (PC), kraft paper, fluorescent paper, gold-plated paper, silver-plated paper, synthetic paper, aluminum foil, fragile (anti-counterfeiting) paper, masking paper, cloth label (Tavik nylon) paper, pearlescent paper, sandwich coated paper, and thermal paper.

Coating material. The coating materials are transparent polyester (PET), translucent polyester (PET), transparent oriented stretch polypropylene (OPP), translucent oriented stretch polypropylene (OPP), transparent polyvinyl chloride (PVC), glossy white polyvinyl chloride (PVC), matte white polyvinyl chloride (PVC), synthetic paper, glossy gold (silver) polyester, matte gold (silver) polyester.

Adhesives. Adhesives include general-purpose super-viscosity type, general-purpose strong viscosity type, refrigerated food strong viscosity type, general re-opening type, and fiber re-opening type. On the one hand, the adhesive ensures the moderate adhesion between the bottom paper and the face paper, and on the other hand, it ensures that the face paper can have strong adhesion to the paste after it is peeled off.

Liner material. Release paper is commonly known as "bottom paper", and the bottom paper has an isolation effect on the adhesive, so it is used as an adhesion of the face paper to ensure that the face paper can be easily peeled off from the bottom paper. Commonly used are white, blue, yellow glassine or onion, kraft paper, polyester (PET), coated paper, polyethylene (PE).

Self-adhesive label printing. It is to print the label with the selected method and coat it with a thin layer of self-adhesive on the back to make a self-adhesive self-adhesive material, and the most printing equipment is used to produce a self-adhesive label.

Features of self-adhesive label printingThe so-called self-adhesive label printing is the process of transferring ink and other substances to the surface of the substrate pre-coated with adhesive layer on the back under a certain pressure. Compared with ordinary printing, self-adhesive label printing has the following characteristics, small investment and quick effect. Self-adhesive label prints are mostly trademarks and stickers, and their format is smaller.

The printing method is flexible, self-adhesive label printing is not limited by the printing method, the traditional printing plant can use offset printing machine or screen printing machine printing, and the new printing plant can use flexographic printing machine or trademark printing machine printing. Self-adhesive label prints can not only be used as trademarks and barcodes for food and cosmetics.
