What do you need to pay attention to when printing transparent PET label paper?

Transparent PET label paper needs to pay attention to the following aspects when printing:

First,Material characteristics and treatment

Surface pretreatment:

Transparent PET film is a plastic film material with low and medium surface energy, and surface pretreatment is required before printing to improve its surface energy or wetting ability. Otherwise, the firmness of the ink may not be good and it is easy to fall off.

The methods of surface pretreatment include corona treatment and surface coating. Corona treatment increases the surface energy of materials by high voltage discharge, but the effect may be unstable. Surface coating is the coating of affinity ink on the surface of the material in advance, which is more ideal, more common and more stable.

Second, printing equipment and Settings

1.Printer compatibility:

Choose a printer suitable for transparent PET label paper, such as a thermal transfer printer, laser printer (check compatibility), inkjet printer (effects may be limited) or barcode printer.

Make sure the printer is set up correctly, including options for paper type, size, print quality, etc.

2.Print parameter adjustment:

According to the characteristics of the transparent PET label paper and the performance of the printer, adjust the printing parameters, such as temperature, pressure, speed, etc., to obtain the best printing results.

For inkjet printers, specific ink types and print patterns may need to be used to ensure transparency and clarity.

Third, ink and consumables selection

1.Special ink:

Special inks are used with transparent PET label paper to ensure the adhesion and durability of the ink.

Special inks usually have better water resistance, oil resistance, scratch resistance and other properties, suitable for labels that require high durability.

2.Consumable quality:

Ensure that the quality of transparent PET label paper meets printing requirements and avoid using expired or damaged label paper.

Fourth,Note in the printing process

1.Electrostatic treatment:

During the printing process, static electricity may affect the transfer and attachment of ink. Therefore, it is necessary to take appropriate electrostatic treatment measures, such as increasing the humidity of the workshop and using electrostatic eliminator.

2.Pollution prevention:

Keep the printing environment clean to avoid contaminating the transparent PET label paper and printer parts with dust and impurities.

3.Real-time monitoring:

Monitor the printing effect in real time during the printing process, find and solve problems in time, such as uneven ink, color deviation, etc.

Fifth,Post-processing and preservation

1.Drying treatment:

According to the need to choose the appropriate drying method, such as natural drying, hot air drying, etc., to ensure that the ink is fully cured.

2.Keep properly:

Store the printed transparent PET label properly, avoid moisture, heat or extrusion, in order to maintain its good physical and chemical properties.

In summary, when printing transparent PET label paper, it is necessary to pay attention to material characteristics and processing, printing equipment and Settings, ink and consumables selection, precautions in the printing process, and post-processing and preservation. Only by comprehensively considering these factors can we obtain high-quality transparent PET label paper printing results.
