How does the printing effect of small roll thermal label paper change in high or low temperature environments?

The printing effect of small roll thermal label paper may undergo significant changes in high or low temperature environments. The following is a detailed analysis of these changes:

The impact under high temperature environment

Color change and fading:

The color change temperature of thermal label paper is usually between 60~200 ℃, but some special materials or coatings of label paper may only begin to change color at higher temperatures. However, prolonged exposure to high temperatures, even if the temperature does not reach the color change point, may cause the label paper color to gradually fade, affecting the printing effect.

When the temperature exceeds the tolerance range of the thermal label paper, the thermal sensitive coating on its surface will undergo a chemical reaction, resulting in a color change. This change may be irreversible, meaning that once the label paper changes color, its printing effect will be permanently damaged.

Coating deterioration:

High temperature environment may cause the coating of thermal label paper to deteriorate, thereby affecting its thermal color rendering function. The deteriorated coating may not accurately respond to the printer's heat source, resulting in poor printing performance such as blurry handwriting and uneven colors.

Paper deformation:

High temperature may also cause physical deformation of thermal label paper, such as curling, expansion, etc. These deformations can affect the normal feeding and printing process of the printer, leading to printing misalignment, paper jams, and other issues.

The impact under low temperature environment

Decreased printing clarity:

Although low temperatures usually do not cause discoloration of thermal label paper, excessively low temperatures may affect its printing clarity. This is because in low-temperature environments, the response of thermal sensitive coatings to heat sources may become sluggish, resulting in less clear printed text.

Material embrittlement:

Long term exposure to low temperature environments may make the material of thermal label paper fragile and prone to breakage or damage during printing or processing.

Humidity impact:

In low temperature and humid environments, the thermal coating of thermal label paper may be more susceptible to moisture and deterioration. This will affect its thermal color rendering function, resulting in poor printing quality.

Response measures

Choose thermal label paper that is resistant to high or low temperatures:

Select thermal label paper with corresponding high or low temperature resistance performance based on the temperature range of the actual application scenario.

Control the temperature of storage and usage environment:

Try to store thermal label paper in a temperature suitable environment and avoid prolonged exposure to high or low temperatures.

When using thermal label paper, ensure that the printer's heat source temperature is moderate to avoid damage to the label paper caused by excessively high or low temperatures.

Maintain appropriate humidity in the environment:

Avoid storing thermal label paper in a humid environment to prevent its thermal coating from getting damp and deteriorating.

When using thermal label paper, ensure that the environmental humidity is moderate to maintain its good printing effect.

In summary, both high and low temperature environments may have adverse effects on the printing performance of small roll thermal label paper. Therefore, when selecting, storing, and using thermal label paper, it is necessary to fully consider temperature factors and take corresponding measures to ensure its printing quality.
