How to use special printing to add color to stationery

The tools are indispensable in our daily work and study. Everyone has to deal with all kinds of stationery more or less. With a wide variety of stationery and a stable market demand, the profits are very limited, which actually puts tremendous pressure on the stationery decoration. How to use printing to enhance the value of stationery in a limited profit space is a new topic.

For stationery, in addition to making them more beautiful, printing can also help them achieve the necessary functions, such as: scale on the triangle, warning signs on the container, letters on the keys, etc. Let's talk about several printing methods for stationery.

The materials used to make stationery include plastics, metals, glass, paper, leather, and wood. Printing on these materials is actually a specialty of the special printing industry. In addition to conventional printing, flexo printing, and embossing, some conventional printing methods can be used. Outside the stationery, the special printing technology represented by pad printing and screen printing is the main player.

Printing

The pad printing process is more suitable for imprinting pad printers with undulating appearance and even larger surfaces. The pad printer uses a soft plastic head to switch back and forth between printing plates and products. It is suitable for products with smaller area. The pad printer is suitable for larger products.

The most significant advantage of pad printing is that it is very adaptable to the surface state of the product, and pad printing often achieves better results when printing is not effective. This is related to the characteristics of the pad printing itself: the pad printing head or cylinder is a tool for transferring the ink, their movement is very simple, and the printing plate system and the work table system have relatively independent positional relationships, and the adjustment is also very convenient. , When the shape of the product changes, we can flexibly adjust their movement relations to achieve the purpose of printing.

Pad printing is also one of the best ways to carry out multi-color printing directly on the surface of a product. Pad printing multi-color structure design is very mature, and the price is relatively cheap, so some bionic stationery often use pad printing to complete overprinting. At present, whether it is screen printing or multi-color foil stamping machines are more troublesome to produce, and the price is relatively expensive, which directly affects the printing possibilities of stationery products such as those with very small profits.

The pen is one of the most widely used stationery. Most of the pens with the most variety are printed by printing. For stationery with a small print area or printing area, you can first think about whether you can use pad printing. Or consider pad printing when you can't find better square strings to decorate your product. If some stationery products are difficult to print with pad printing, other methods are more difficult.

The biggest advantage of screen printing is that it is very adaptable to the material of the product. It is claimed that there is no printing method other than air and water. As long as we can find the right ink and dry it properly, then the complex problems can be solved. The method of screen printing transfer by printing has historically been considered to be the method with the least requirement for the ink and the least influence on the physicochemical properties of the ink. If we encounter stationery made of some resin or special plastic, we can use screen printing first. Process.

At present, screen printing is also one of the most effective ways of direct printing on the surface of an ellipsoid and a cylinder. Office stationery produced by some big companies for customers often contains exquisite ellipsoidal or cylindrical components. The pattern on it is often screen printed. Pen products often involve screen printing. .

Flat-screen stationery products use screen printing, such as pen holders, photo frames, tool boxes, and motto plates that are placed on the table. They are usually made of transparent organic glass and glass, and users can easily see the inside. The thing that is most commonly used in the above printing is screen printing. We can easily find transparent screen printing inks and various functional screen printing inks to decorate them. Screen printing can make the original simple little things bright and dazzling.

Screen printing is a direct printing process, so many workers engaged in screen printing will naturally think of using screen printing process to reproduce exquisite dot image on stationery. In the past, many people put a stationery landscape ornament on the offset landscape for a visually enjoyable experience. However, this does not necessarily reflect individual requirements. The level has not been effectively improved, so many practitioners are considering how to Use screen printing to achieve the purpose

Hot stamping

Bronzing is a packaging and decorating process in which a metal layer deposited on the surface of a plastic film layer is transferred to a product by hot pressing. The effect of bronzing is obvious. Its transfer layer is metal instead of ink, so the printed patterns and text are much more eye-catching and most likely to be enjoyed by consumers.

Hot stamping is suitable for both flat products and non-planar products with smooth surfaces. Sometimes we often make stationery more complicated appearance, but as long as we make appropriate bending of the fixture and hot stamping, the application scope of hot stamping will be even greater. Circular products are one of the more common forms. Although we can easily reproduce printed texts by screen printing, foiling is required for striking performance. A curved hot stamping machine is therefore required.

To make stationery more attractive to consumers, it is necessary to use various colors of gold foil paper. Those foil stamping paper manufacturers not only greatly improved the color, but also applied advanced anti-counterfeiting measures to the printing of gold foil paper, which not only improved the grade of stationery, but also had patent protection.

In the bronzing process, the materials used for making stationery are very strict. If proper surface treatment is not performed, such as glass or metal, basically no bronzing can be performed, and the effect of bronzing in wooden stationery will be very poor. Therefore, we must adopt necessary methods. Undercoat technology. When we used the paints that were specially formulated for the printing industry to paint the bottoms, hot stamping brought metal and glass screen-printing “faithful friends” to a close. As for wooden stationery, as long as you choose a good paint, the effect of bronzing is almost as perfect as paper bronzing.

Thermal transfer

Stationery printing is sometimes difficult to achieve accurate color registration, the transfer process allows us to achieve a one-time multi-color printing at low cost.

Printing on plastic film is not only fast but also includes thermal transfer in two ways: one is a thermal transfer film, and the thermal transfer film combines a gravure printing process with a unique printing process to transform the PET film into a multilayer printing structure. As a result of the final transfer, the image layer built on top of the PET film is completely peeled off; the other is the thermal transfer process. The heat transfer process uses a silica gel sheet and a silicone roller capable of heat transfer to apply pressure for transfer purposes. .

The thermal transfer process is ideal for products such as packaging boxes. Its appearance requires delicate decorative patterns, and its intrinsic value will be significantly improved. The thermal transfer process is also very suitable for cylindrical stationery products. The unfolded surface of the cylindrical product is a flat surface, which makes the decoration of cylindrical stationery products as easy as flat surfaces. Compared with screen printing, although screen printing is difficult to find competitors for round products, screen printing still has certain limitations in terms of one-off printing.

Also, the surface of the stationery product is not flat but has a smooth transitional surface, but as long as a heat transfer machine with a floating mechanism is used, exquisite thermal transfer can be realized.

Water transfer printing

The mystery of water transfer printing has gradually disappeared, and more and more people understand its technical mysteries and begin to adopt it on a large scale in the stationery industry. Water transfer printing technology uses gravure printing technology to accurately print on water-soluble film. We only need to modify the heat transfer gravure printing process to use the water transfer process. However, the water transfer process is more complicated than the thermal transfer process. The water-soluble ink used in the water transfer process makes it necessary to activate the image layer on the transfer film to an independent state during the transfer process. In principle, all materials can be water-transferred, so the water transfer application is more extensive.
