How to choose the appropriate ink when printing PET matte silver thermal paper?

Choosing the appropriate ink is crucial when printing PET matte silver thermal paper. Here are some suggestions to help you make wise choices:

1、 Consider ink type

For the special properties of PET matte silver thermal paper, the following ink types are recommended:

UV ink:

Advantages: Fast drying speed, not easy to fade, no need for volatilization, can effectively improve production efficiency and printing quality.

Attention: When choosing UV ink, consider the special properties of matte silver paper material, conduct experiments and tests to ensure printing quality.

Solvent based ink:

Advantages: It has good adhesion and coverage, suitable for various printing methods.

Attention: Solvent based inks may require baking or natural drying, so it is important to ensure that the printing equipment has the appropriate drying capacity.

2、 Evaluate ink performance

When selecting ink, it is necessary to evaluate its following properties:

Adhesion: The ink should be able to firmly adhere to the surface of PET matte silver thermal paper without easily falling off, to ensure the durability of the printed product.

Color stability: The color of the ink should be stable and not easily fade to ensure the long-term preservation effect of the printed matter.

Drying speed: The drying speed of ink should be moderate, which can meet production needs and ensure printing quality.

3、 Consider printing technology

When choosing ink, it is also necessary to consider the requirements of the printing process:

Printing method: Select the appropriate ink type based on the type of printing machine and printing method (such as roll to roll printing, flat printing, etc.).

Printing speed: High speed printing may require selecting ink with faster drying speed to ensure production efficiency.

Printing effect: Select the appropriate ink type based on the desired printing effect (such as matte, glossy, etc.).

4、 Ink brand and supplier selection

Brand reputation: Choose ink from well-known brands to ensure the quality and stability of the ink.

Technical Support: Choose ink suppliers who can provide technical support to ensure timely resolution of any issues encountered during the printing process.

Price and cost-effectiveness: Considering the price and cost-effectiveness of ink while ensuring quality, in order to reduce production costs.

5、 Precautions for Ink Use

Ink mixing: If different types of ink need to be mixed, a test should be conducted in advance to ensure the stable performance of the mixed ink.

Ink storage: Ink should be stored in a cool, dry, and ventilated place, avoiding direct sunlight and high temperature environments.

Ink replacement: When replacing ink, the printing equipment and tools should be thoroughly cleaned to avoid mixing between different inks that can lead to a decrease in printing quality.

In summary, when printing PET matte silver thermal paper, selecting the appropriate ink requires comprehensive consideration of factors such as ink type, performance, printing process requirements, and ink brand and supplier selection. By scientifically selecting and using ink, the quality and production efficiency of printed materials can be ensured.
