What Are Offset Printing Applications
Offset printing is a process of transferring images and texts through rubber cloth. With its high cost-effectiveness, high degree of restoration and wide adaptability, it has shined in many fields.
Packaging printing
1. Carton color boxes
With the booming development of e-commerce logistics, the demand for printing corrugated boxes has surged. Offset printing with PS sheet can present clear brand LOGO and transportation logo on the rough box surface. The color box printing of high-end cosmetics and electronic products relies on CTP plate (computer to plate). Its micron-level dot accuracy allows the gradient color and hot stamping lines to be perfectly presented, and with matte/gloss film technology, it creates a packaging texture with excellent touch and vision.
2. Metal packaging
Curved printing of beverage cans and milk powder cans is the forte of offset printing. Metal plates (after special oxidation treatment, can achieve uniform ink adhesion on curved substrates, combined with UV curing technology, so that the red color of the Coke can is always bright and resists the erosion of the humid environment.
Publication printing
1. Books and magazines
The massive printing of primary and secondary school textbooks and fashion magazines relies on the stable performance of traditional PS plates. Its printing life can reach more than 100,000 prints, which can ensure the color consistency of tens of thousands of books. For the high-precision printing of art albums, thermal CTP plates are used.
2. Bills and certificates
The printing of VAT invoices and graduation certificates has hidden secrets. The multi-layer coated PS plate is combined with fluorescent ink to form special patterns on the surface of the plate. The printed anti-counterfeiting code shows a unique pattern under ultraviolet light, and the friction-resistant ink formula makes the text still clearly visible after ten years.
Advertising media
1. Outdoor advertising
The long-term outdoor display of bus shelter posters and car body advertisements requires the plate to have super weather resistance. The CTCP plate is matched with UV-resistant ink to achieve 300dpi high-resolution printing on aluminum plates or spray-painted cloth. Even after heavy rain and scorching sun, the color retention can still reach more than 2 years.
2. Promotional materials
The short-run printing of supermarket DM sheets and exhibition brochures, the processing-free CTP plate is very useful. The environmentally friendly characteristics of not requiring chemical development shorten the time from design to printing to less than 2 hours, and with digital proofing technology, the corporate standard color of the PANTONE color card can be accurately restored.
Specialty Printing
1. Label Printing
The curved printing of wine bottle labels and pharmaceutical anti-counterfeiting labels relies on the innovative combination of flexible resin plates and offset printing. By customizing the curved rubber blanket, non-stretching deformation printing is achieved on the surface of the 3cm diameter medicine bottle. With the help of temperature-dependent ink, the label can show hidden information at body temperature.
2. Industrial Manufacturing
The printing of the solder mask layer of the circuit board and the scale marking of the car dashboard require ultra-high-precision metal plates. Through laser engraving technology, a 10-micron-wide wire groove is made on the stainless steel plate to achieve an overprint accuracy of 0.01mm, ensuring that the automotive electronic components are clearly marked in extreme environments of -40℃ to 85℃.
