The printers that most people know are usually needles, ink jets, and laser printers, but you may not notice that almost all of the products in our environment have labels printed using thermal transfer technology. For example, Open the phone case, inside can see densely packed with bar code labels, generally high-grade packaging of wheat head has a thermal transfer printed out of a product label stickers, usually with a bar code. In addition, when purchasing clothes, the tag on the clothing is usually printed by thermal transfer printing. Train tickets, boarding passes, and luggage tags purchased at the train station are all printed using thermal transfer technology. In particular, behind almost all electrical products, there are some label labels printed using thermal transfer technology. Like laptop computers, there are more than one label printed in this way. Why use thermal transfer printing, how is heat transfer generated?
Because there are many labels, it must be able to withstand the test of time, long-term invariability, text must be stored for a long time, can not fade, can not wear because of contact with the solvent, not because the temperature is higher deformation, and so on, so it is necessary to use a special Material print media and printing materials to ensure these characteristics, the general inkjet printing technology can not be achieved, laser printing can not be achieved, but the effect of the needle and the original design can not meet the requirements, so with the emergence of thermal transfer technology. Thermal transfer technology, simply put, is the use of a special ribbon, through the working principle of a fax-like print head, the toner coating on the ribbon is heated to transfer to paper or other materials In addition, because the coating material on the carbon ribbon can be selected according to need, resulting in strong adhesion, plus the choice of print media, it can ensure that the printed handwriting is not affected by the outside world. And this heating process, how to heat, can be given to the computer to control. At present, since various softwares have been developed to print labels, it is very convenient for the users, especially in general. Labels must generate bar codes. The production of bar code symbols has therefore become an indispensable tool for such software.
The general printer design is usually designed for A4 paper size. Some people must order separately to print on such a paper, which is very uneconomical. Moreover, for the factory, sometimes the number of prints must reach one hour. Thousands of prints, these printers on the market can not be completed, so design a printer that can print continuously and quickly for small paper. In the case of ARGOX printers that are common on the market, printing can be done up to 10 meters per minute. If a label is 2 centimeters high, it can print 500 sheets in a minute. A dedicated label printer is more than that. It also addresses the needs of the factory. It can be combined with a scanner or keyboard and can be operated independently. It does not necessarily require a personal computer to operate. Just like a photo printer now, it can read data directly. No longer need to rely on computers to save extra investment in factories.
Powder puffs are pieces of soft material used for the application of face powder. They may be shaped as balls or pads.
Historically, powder puffs have been made of very fine down feathers, cotton, fine fleece, etc.
In modern times synthetic materials are widely used for powder puffs.
In addition to softness, an important characteristic of powder puffs is their intake ability, i.e., the ability to hold powder.
It was reported that for synthetic fibers important factors in designing high-intake powder puffs are mostly geometric ones: fiber diameter, pile length, and space between fibers, with little dependence on material factors.
Makeup puff have different shape.

5.oval shape puff
