Offset Paper
Offset paper is a type of paper that is used for printing high-quality color printing products. It is designed to have good water resistance, dimensional stability, and strength, which are necessary for the water-ink balance principle used in printing. To produce accurate color tones, Offset paper needs to have a certain level of whiteness and smoothness. Its features are as follows:
- High whiteness
- Good stiffness
- High strength
- Smooth and delicate surface
- Accurate overprinting
- Clear printing
- Good surface strength, no shedding or dusting during printing
- Low extensibility
- Consistent basis weight, thickness, and moisture content
Overview
Offset paper is mainly used for printing high-quality single-color or multi-color printing products on flat (offset) printing presses or other printing machines. It is suitable for printing single-color or multi-color book covers, text, inserts, posters, maps, promotional pictures, color trademarks, and various packaging products.
In recent years, as people's cultural and living standards have improved, the demand for high-end books and printed materials has increased. Offset paper has become a popular choice for printing books, journals, and other printed materials due to its advantages of high whiteness, stiffness, smoothness, and fine texture. Printed materials made with offset paper have clear text and flat pages that are not easily deformed.
