It can usually be seen from the following aspects:
1. The carbon has pinholes (bubbles): caused by the ink not being evenly coated. Will cause incomplete characters when printing.
2. Ribbon wrinkles: Due to problems with the tension control system during slitting, there will be no words printed on a small area of the ribbon. Because the melting temperature of the two layers of ribbon is much greater than the temperature of one layer.
3. Carbon with blank: As the light film is not processed well, it will cause more than the out of the blank.
4. The tolerance of the inner diameter of the paper core is too large or too small: the printer cannot be installed or the ribbon cannot be taken up by the shaft.
5. Too high temperature during transportation will cause the ribbon to stick together.
6. Whether the paper core runs off: it will cause the tape to break and the edges will not be printed.
7. The ribbon length is not enough.
8. When the ribbon is being processed, the winding is too tight or too loose, causing the ribbon to be unable to match the printer during operation.
9. To be shoddy, the wax-based component is too high and the resin component is too small, resulting in the inability to show the advantages of the mixed-based.
Generally speaking, it is not an easy task to purchase the right ribbon. Different printers have different printing preferences, and different printing media will affect the printing effect. Now, the price of ribbon can be said As the domestic processing capacity becomes more and more popular, the price is getting lower and lower. If you want to purchase cheap and easy-to-use ribbons, you really must have a real knowledgeable person to guide, otherwise the bad printing effect will directly affect the product. image of.
In addition, a small number of imported printers specify the use of special printing ribbons, the effect is not necessarily significantly better than the general printing effect, and the price of the ribbon is very expensive, this is where you must pay special attention when purchasing printers. Because now, the price of the universal thermal transfer ribbon, which is constantly falling, is lower than the price of ink for inkjet printing, but the same as toner for laser printers.
