In China's label printing market, embossing technology occupies a pivotal position. This aspect is due to the impact of embossing technology on the entrenched nature of China's label printing industry. On the other hand, embossing equipment suppliers are actively carrying out The improvement and improvement of the equipment has kept this traditional technology alive. In the technological innovation of embossing equipment, there are two items:
1. Satellite label embossing machine processing multi-layer labels
Shanghai Sun Machinery Co., Ltd. demonstrated the innovative application of its fist product, TLC-250-8C+1F self-adhesive rotary press, at the 2012 China International Label Technology Exhibition, providing a new, simple and economical industry. The multi-layer label processing method is very worthy of attention. The TLC-250-8C+1F self-adhesive rotary press machine successfully completed the rubber surface with a roll of film adhesive material (the left and right parts of the roll material were printed on the upper and lower layers of the double-layer label respectively). Printing, front printing, slitting, compounding, die cutting and other processes have made a special double-layer label. The specific printing process is as follows.
(1) Rubber surface printing.
(2) Surface printing on the surface material.
(3) Cutting.
(4) The base paper is peeled off and composited.
(5) Die cutting.
(6) Finally enter the cutting station and cut into small sheets.
2. Innovation of round flattening label printing machine
Shenzhen Dangfa Machinery Manufacturing Co., Ltd. exhibited the “New Rotary Machine†series of flat-pressed label embossing machines exhibited at Sino-Label2013. Although it is a “platform machine†structure, it has printed the label of the “rotary machine†effect. The technological innovations and ideas made are amazing, and the core technology adopted has obtained national patents.
In appearance, this "new type of rotary machine" is almost the same as the traditional "back-slanting machine" (the difference between the paper feeding system and the inking system of the two types of equipment), but it is actually a kind of domestic label. A new type of round flattening label embossing machine that is not in the printing equipment and is completely different from the traditional round flat label embossing machine. In the printing system of the equipment, the movement of the embossing cylinder is very special - both "revolution" "Autobiography" (similar to the operating principle of satellites). In the process of "revolution" and "autobiography", the impression cylinder is in contact with the printing plate to realize one printing, and the entire circular flattening printing process is completed repeatedly. Such a printing method requires the paper feeding system to cooperate with the impression cylinder to perform intermittent pause and paper feeding, and finally realize intermittent circular flat printing.
From the mechanical principle, the "new type of rotary machine" of the mechanical machine is essentially different from the traditional round flat label printing machine. The printing cylinder of the traditional circular flat labeling printing machine runs in the same direction as the paper feeding direction, and the printing plate cylinder is reciprocating. This structure causes the printing speed of such printing equipment to be unsatisfactory, and the vibration during operation is large. It is easy to wear and eventually leads to poor printing quality. The round flat label embossing machine of the mechanical machine made a breakthrough innovation. The embossing roller runs in the same direction as the paper feeding direction, and the embossing roller runs continuously without interruption, and can operate relatively fast and vibrate. Small, parts wear is small, printing quality is good, and the impression cylinder is easy to replace and the price is also cheap. This "new type of rotary machine" can achieve clear and non-deformation of printed products, uniform pressure and no color cast, and white ink on the reverse. There is no common "double eyelid" and "dip" on the printed product due to excessive printing pressure. "Phenomenon." This equipment is very suitable for domestic label printing companies, especially those that use PET film-based printing materials and print on-site anti-white text electronic labels.
