What consumables are there for self-adhesive printing machinery?

In the field of self-adhesive printing, the normal operation of self-adhesive printing machinery cannot do without the support of various consumables. These consumables directly affect the printing quality and cost. Understanding them is of vital importance to practitioners.

Ink consumables

Solvent-based ink: It was once a commonly used ink for self-adhesive printing. It features excellent drying speed and color expressiveness, and can achieve firm adhesion on a variety of self-adhesive materials. However, due to the presence of a large amount of volatile organic compounds (VOCs), which pose certain hazards to the environment and the health of operators, its use is gradually being restricted in the current context of increasingly strict environmental protection requirements.

Water-based ink: As an environmentally friendly ink, it uses water as the solvent and has extremely low VOCs emissions. Water-based ink in self-adhesive printing features bright colors, good stability and strong adaptability to substrates such as paper. It is especially suitable for label printing on food, medicine and other products with high safety requirements, and can effectively avoid the risk of ink contamination.

UV ink: This type of ink cures instantly under ultraviolet light and features fast drying speed, a strong and wear-resistant ink layer, and other advantages. On self-adhesive printing machinery, UV ink can achieve high-precision printing, especially suitable for printing on self-adhesive materials with smooth surfaces such as plastic films and metal foils, presenting fine patterns and rich color gradation.

Paper and self-adhesive material consumables

Ordinary self-adhesive paper: It is one of the most common consumables and is divided into different types such as coated paper and offset paper. Coated paper has a smooth surface and a fine printing effect, and is often used to make labels for high-end products. Offset paper is relatively inexpensive and suitable for general label printing. It has good ink absorption and printability.

Special self-adhesive materials: including thermal paper, laser paper, waterproof paper, etc. Thermal paper changes color when heated and is often used to make price tags, logistics labels, etc. Laser paper has a unique optical effect, which can enhance the anti-counterfeiting and aesthetic appeal of labels and is often used in the packaging of high-end products. Waterproof paper is suitable for label printing on outdoor products, liquid packaging and other items that have requirements for waterproof performance.

Printing plates and other consumables

PS plate: Widely used in traditional self-adhesive printing machinery. Through plate-making processes such as exposure and development, the graphic and text information is transferred onto the PS plate, and then the ink is transferred onto the self-adhesive material by the printing machine. The quality of PS plates directly affects the printing accuracy and the degree of graphic and text reproduction.

Blanket: As an important consumable in the printing process, it is used to transfer ink. High-quality rubber blankets have excellent elasticity and wear resistance, which can ensure the uniform and accurate transfer of ink, improve printing quality and extend service life.

Squeegee: In flexographic self-adhesive printing machines, the squeegee is used to control the amount of ink transfer and ensure the clarity of the printed pattern. The material and precision of the ink scraper have a significant impact on the printing effect and need to be replaced regularly to maintain good printing performance.

The types of consumables for self-adhesive printing machinery are rich. Reasonable selection and use of these consumables are the key to achieving efficient and high-quality self-adhesive printing.
