Printing technology of self-adhesive labels

  1. Offset Printing: Offset printing is a commonly used printing technology suitable for large-scale production. It utilizes an inked roller and printing plates to indirectly transfer ink onto the printing substrate. During the offset printing process, ink is transferred to the recessed areas of the printing plates, then onto a rubber roller, and finally onto the printing substrate. Offset printing achieves high resolution, multicolor, and detailed print results.
  2. Letterpress Printing: Letterpress printing is a traditional printing technique that uses raised patterns or letters for printing. In letterpress printing, the printing patterns or text are raised, and ink is directly transferred to the printing substrate. This technique produces a thicker ink layer and sharp patterns.
  3. Flexographic Printing: Flexographic printing is a commonly used printing technology for self-adhesive labels. It utilizes flexible plates, rubber rollers, and ink chambers to transfer ink onto the printing substrate through rotating cylinders. Flexographic printing is suitable for high-speed, large-scale production and achieves high resolution and precise pattern and text printing.
  4. Digital Printing: Digital printing is an advanced printing technology that directly prints patterns and text onto the printing substrate from computer files using digital printing equipment. This technology eliminates traditional printing preparation processes and offers advantages such as speed, flexibility, and customization. Digital printing is suitable for small-scale production and diverse printing needs, providing high-quality printing results.
  5. Hot Foil Stamping: Hot foil stamping is a commonly used printing decoration technique that adds metallic foil patterns to self-adhesive labels. It utilizes heated metal plates and pressure to transfer the metallic foil onto the printing substrate. Hot foil stamping creates shiny and high-quality decorative effects.
  6. UV Printing: UV printing is a special printing technology that uses UV-curable inks. In UV printing, UV-curable inks based on photoinitiators are cured through UV exposure during the printing process. UV printing enables fast drying and high-quality print results as the ink instantly cures without waiting time.
  7. Cold Foil Printing: Cold foil printing is a technique similar to hot foil stamping for adding metallic foil to self-adhesive labels. The difference is that cold foil printing utilizes an adhesive to attach the metallic foil to the printing substrate without the need for heat pressure.
