How does the surface smoothness of BOPP color thermal sensitive synthetic paper affect printing quality?

The surface smoothness of BOPP color thermosensitive synthetic paper has a significant impact on printing quality. The following is a detailed analysis of this impact:

1、 Affects the ink transfer effect

High smoothness: When the surface smoothness of BOPP color thermosensitive synthetic paper is high, ink can be transferred more evenly and completely from the print head to the paper surface. This helps ensure the clarity and consistency of printed content, especially when printing fine patterns or text.

Low smoothness: If the surface smoothness of the paper is low and there are unevenness, the ink may be disturbed during the transfer process, resulting in uneven ink distribution. This may result in blurry, broken lines, or uneven colors in the printed content.

2、 Affects color accuracy

High smoothness: A smooth paper surface helps ink form a uniform ink film, and the reflection and refraction of light on the surface of the ink film are more regular. This helps ensure consistency between printed colors and the original design, improving color accuracy.

Low smoothness: Uneven paper surface may result in uneven ink film thickness and irregular light reflection and refraction after ink drying. This may cause differences between the colors seen by the human eye and the expected colors, affecting the overall visual effect of the printed product.

3、 Affects printing glossiness

High smoothness: Paper with high smoothness can enhance the glossiness of printed products, making them look more shiny and textured. This is particularly important in situations where high gloss printing effects are required, such as product packaging, advertising materials, etc.

Low smoothness: A rough paper surface can make the ink film uneven, causing light to scatter on the surface of the ink film and unable to form a good reflection effect. This may reduce the glossiness of the printed product, making it appear dull and lackluster.

4、 Affects printing speed and efficiency

High smoothness: A smooth paper surface helps to quickly dry and fix ink, thereby improving printing speed. At the same time, reducing the number of repeated printing or corrections caused by uneven ink transfer and improving printing efficiency.

Low smoothness: Uneven paper surface may result in uneven ink drying speed, and even ink accumulation or poor drying in certain areas. This may slow down the printing speed and increase the failure rate during the printing process.

5、 Affects the durability of paper

High smoothness: A smooth paper surface usually means better coating quality and tighter fiber structure, which helps improve the durability and wear resistance of the paper.

Low smoothness: Rough paper surfaces may be more susceptible to wear and scratches, reducing the lifespan of the paper.

In summary, the surface smoothness of BOPP color thermosensitive synthetic paper has a significant impact on printing quality. To ensure the best printing effect, it is recommended to consider the surface smoothness and other related factors such as ink type, printer compatibility, etc. when selecting paper.
