The Application Of Embossing What Is The Application Of The Shenzhen Folding Box Printing Factory In The Printing Of Security Labels?
- May 07, 2018 -

The security printing of the Shenzhen Folding Box Printing Factory is generally based on embossing, and only a few use the sheet-fed offset printing method. Therefore, the characteristics of embossing technology and sheetfed offset printing in the printing of anti-counterfeiting labels are analyzed first.

First, production efficiency and printing costs

The connection between the printing process of the embossing and the post-processing process is more and more. It can be realized with the printing methods of offset printing, gravure printing, screen printing, digital coding, and the connection combination of cold pressing, die-cutting and other processing devices. Production from the feeding to die cutting into finished products is possible at one time, with high production efficiency and low printing costs. Sheet-fed offset printing labels are usually printed first and then processed one by one into finished products. Therefore, the production cycle is longer and the corresponding printing costs are higher.

Second, drying speed and drying effect

In the field of printing, the convex printing machine generally adopts the UV curing method, which has a fast drying speed and a good drying effect. For example, in the solar satellite rotary press, each press base is equipped with a set of UV curing devices. When printing a large area on the ground, the operator can increase the ink volume so that the printed ink layer is thick and textured. The ordinary sheetfed offset printing press does not have a UV curing function, and the printed ink cannot be dried immediately. Therefore, when printing a large area on the ground, if the layer of ink is thick, it can easily cause sticky and poor ink drying.

Third, screen printing

In the case of halftone printing, offset printing is more advanced, and the transition from flat screen to screenless network is natural. However, the embossed stamp is poorly represented. When transitioning from flat screen to screenless screen, the screen area ratio is approximately 3%. Showing disconnection phenomenon. However, with the rapid changes in the direct plate-making skills of Embossing, the embossing of the site's dot-score rate does not indicate a disconnection from 1% to 99%.

Fourth, plastic surface printing

Gum-blood printing is a special printing method that the printing technology has. Now, offset printing machines have not involved this method. The so-called plastic surface printing is to peel off the backing paper of the self-adhesive material during printing, and then print on the “glue surface” with the adhesive, and then compound the bottom paper with the backing paper. Continually printing on the surface material and making the product, this printing method requires a higher skill level, and a unit with a back print function is installed on the embossing. In general, the plastic surface printing is to print the "glue surface" and then print the front surface. Therefore, the first few units of the convex printing machine must be converted into adhesive printing units. In addition, we must also pay attention to overprinting, printing pressure manipulation, data flatness and other issues when printing on both sides of the front and back.

V. Anti-counterfeiting

Printing presses with printing methods such as embossing printing, screen printing, gravure printing, offset printing, etc., can realize complementary advantages among various printing processes on a label, making labels more compact and more anti-counterfeiting. Shenzhen Folding Box Printing Factory It is thought that the use of a label printed on a combination printer has a considerable difficulty in copying. If the counterfeiter wants to use a single printing method to fake the label printed by the combination printer, the secondary tracking problem must be handled, otherwise an overprint error will occur and the original label cannot be reproduced.

From the above comparison, it can be seen that printing a security label using the embossing method has certain advantages. And it is also true that the current market contains electronic code, two-dimensional code, bar code anti-counterfeit labels to the majority.

The application of embossing technology in anti-counterfeiting labels is far more than mentioned in the text. There are many aspects. It is believed that with the continuous advancement of embossing technology, embossing will still play an important role in the field of security labels.
