What are the factors that affect the printing quality of small roll thermal label paper?

The factors that affect the printing quality of small roll thermal label paper mainly include the following aspects:

1、 Thermal paper quality

Thermal sensitive coating:

Uniformity: The uniformity of the thermal sensitive coating directly affects the printing quality. If the coating is uneven, it can cause some areas to have darker colors and others to have lighter colors during printing, resulting in a significant decrease in print quality.

Formula: Whether the chemical formula of the thermal sensitive coating is reasonable is also crucial. Unreasonable formula may result in shorter storage time of printing paper or poor printing effect.

Protective layer:

The protective layer can absorb some of the light that causes chemical reactions in the thermal sensitive coating, slow down the deterioration of the printing paper, and protect the thermal sensitive components of the printer from damage. If the quality of the protective layer is poor, it will affect the storage time and printing quality of the printing paper.

2、 Production equipment and processes

Production equipment:

The accuracy and stability of production equipment have a direct impact on printing quality. If the accuracy or stability of the device is insufficient, it can lead to poor printing results.

Production process:

The precision of the production process can also affect the printing quality. For example, in the process of applying thermal sensitive coatings, improper process control may lead to uneven coating thickness or coating detachment.

3、 Usage environment

Temperature:

The printing quality of thermal paper is affected by temperature. When the temperature is below a certain range, it takes a considerable amount of time for the paper to develop color; When the temperature is too high, it may cause the thermal sensitive coating to react too quickly, resulting in printing quality issues.

Humidity:

Excessive humidity may cause thermal paper to absorb moisture and deform, affecting print quality. At the same time, humidity may also affect the chemical reaction rate of thermal sensitive coatings, thereby affecting the printing effect.

4、 Printing parameter settings

Printing temperature:

The setting of printing temperature has a direct impact on printing quality. Low temperature may result in unclear printing, while high temperature may damage the thermal sensitive coating.

Printing speed:

Printing speed can also affect printing quality. Too fast speed may result in unclear printed content, while too slow speed may waste time and resources.

Printing pressure:

The setting of printing pressure is equally important. Insufficient pressure may result in unclear printing, while excessive pressure may damage the thermal paper or print head.

In summary, to improve the printing quality of small roll thermal label paper, it is necessary to start from multiple aspects such as thermal paper quality, production equipment and technology, usage environment, and printing parameter settings. Only by comprehensively considering these factors and taking effective measures to control them can we ensure the printing of high-quality thermal label paper.
