[China Packaging Network News] Nowadays, with the rapid advancement of technology, new technologies and new technologies are gradually emerging. The excellent performance characteristics are constantly impacting the traditional processing methods and injecting momentum into current processing production.
Since the advent of laser technology, with its unique advantages and excellent performance characteristics, it has been favored by many enterprises and widely used in many industries. Its unique processing form provides many creative ideas for production and processing. So, what happens when laser technology is integrated into the printing industry?
Since its inception, laser marking machines have been widely used in various fields due to their unique advantages and excellent performance. Every step of the
Laser Marking Machine has experienced people's criticism and questioning. Each innovation is the performance of the development of science and technology. The control system has experienced the large-format era, the rotating mirror era and the galvanometer era in the field of laser marking machines. The control mode has also completed a series of evolutions from software direct control to real-time processing and time-division multiplexing. Today, semiconductor lasers and optical fibers The emergence of lasers and ultrafast lasers poses new challenges to optical process control.
The laser machine has the advantages of high engraving accuracy, non-contact, permanent, anti-counterfeiting, and high processing efficiency. Compared with traditional screen printing and pad printing machines, what are the advantages and disadvantages?
We first distinguish from the color, the laser can not hit a variety of colors so far, it is through the light of high temperature and chemical reaction of the material surface, showing the color, usually three kinds of black, white, yellow. Screen printing, printing of colors they can show, colorful, it is through the ink mix, ink only has six basic colors, red, yellow, blue, black and white, and a variety of colors from the six colors of the reconcile Matching ratio.
From the perspective of production applications, we can appreciate the charm of laser marking machines from six angles: speed, efficiency, degree of use, difficulty of operation, potential safety hazards, and product demand.
Speed, laser from the typesetting to LOGO forming, occupy an absolute advantage, get rid of the screen printing, printing, from the production of film - plate - weaving network - drying plate - transfer ink - fixture - printed on the LOGO. Every step in the middle can't go wrong. The complexity of the process is far beyond your imagination. The laser from the graphics - typesetting - positioning - play LOGO, the middle process as long as the two software, the operation is simple, the error rate is low.
In terms of efficiency, lasers are free from consumables, eliminating the need for ink in screen printing. In the operation of the worker, the laser only needs to adjust the image file. In the process of using the screen printing, the workers are required to pay attention to whether the network is blocked or not. The printed image has a section, the mesh surface is neat, and the external environment is clean and dust-free.
The extent of the use of silk screen or occupy the bulk of the market, after all, it is veteran, in many products LOGO expression laser is not as good as the colorful changes in silk screen, laser's single color limits the development of laser in many industries.
In terms of operation difficulty, the laser marking operation is simple and the screen printing operation is meticulous. The laser operation pays attention to the operation software of the CDR and the laser machine. Therefore, as long as you learn about the computer, it is not an issue. In silk screen printing, you first need to select the ink, choose the color you want, and get the color you want through the combination of one or more colors. Put the ink into the stencil. You must devote yourself to the process of using it. Each time you print a part of your product, you will have to repeat several actions, the strength of the doctor blade, whether the screen is blocked, whether the screen is dirty, the amount of ink, and the uniformity of the ink printed on the product.
In terms of safety hazards, lasers are dazzling glare, and the inks are volatile gases. Lasers will inevitably produce some smoke and dust when playing LOGO. Ink (components) will produce an odor during the process of reconciliation and printing. These are all harmful to the body, but the laser can be equipped with ventilation. This problem is solved by the machine, and silk screen printing is indeed unable to effectively improve the entire work environment.
In terms of product demand, the comprehensiveness of laser aspects is still far higher than that of screen printing. Lasers are far superior to screen printing in terms of LOGO forming, speed, operation, and manpower.
Such as laser marking machine in the electronic industry applications, in the application of aerospace technology, in the application of sanitary ware and cosmetics, food packaging, pharmaceutical packaging and a wide range of metal and non-metallic materials. Such as these shows that the laser marking machine has penetrated into all aspects of people's lives and work. In short, because the performance of laser marking machines is far higher than the advantages of traditional screen printing and pad printing machines, its application prospects can be foreseen. Laser marking machines will also have a small market in the future, even as the process requirements increase.
