Test the authenticity of thermal paper  

There are many thermal-type fax using thermal paper, thermal paper is cheap, but there are a lot of fake and shoddy products. These products are characterized by: shorten the already very short shelf barcode printer prints. This is because the counterfeit product coating is very thin, easily destroyed and affect the stability, if stored in a bad environment, these products may even appear not used thermal paper prematurely substances react with the surrounding environment, can not lead to conditions used. Barcode printers based on the author's experience, if the thermal paper white exaggeration, it shows that this is a serious bar code printers shoddy products. Because thermal paper coating material is not white, the color of Taebaek by adding a plethora of fluorescent agents to achieve, as with some copy paper, thermal coating and thermal paper these additives will react and affect the stability of bar code printers, which also may cause thermal coating thickness is mainly the effect of shortening the shelf life of the print. Good thermal paper should be able to see a little bit of hair green or dark green. At the same time the paper should try to smooth consistency and stability barcode printer products such coatings are good.
 
In addition, when we wish to inspection at the back of the paper is heated with a lighter moment, artificial imitation of what print (thermal coating is heated from the changes) if the thermal paper is very evenly heated part of the color change, indicating that the product is good. If the color is very light it shows the amount of product quality barcode printers very general. If the ambient temperature is relatively high and there is no lighter, you can use nails painted look on paper, part of the same color effect scratches can provide a reference for your purchase.
 
As to save time, you can look with a fingernail scratch paper, the relatively strong light and a relatively high degree of temperature barcode printers, color faster, more stable, while saving time is not too long, and demonstrate this coating thickness of the product does not work.
 
With the above method in short, we will be able to buy good quality crow of thermal paper.
