Lithography, also known as offset printing, is one of the four traditional printing processes and one of the most widely used and mature technologies in the printing industry. With the advantages of accurate color reproduction and efficient mass production, it occupies a dominant position in the printing market. Its core principle is based on “oil-water separation”: the image and text areas are oil-philic and water-repellent, while the blank areas are water-philic and oil-repellent, and the ink is indirectly transferred through a rubber blanket to achieve a clear and uniform printing effect.

The key to lithography lies in plate making and ink-water balance control. After exposure and development, the plate forms a clear image outline. During printing, the ink-water ratio needs to be accurately adjusted to avoid problems such as blurring and white exposure. This process features fast printing speed, thin and uniform ink layer, high color reproduction, which can accurately present complex patterns and delicate gradients. It has low cost in mass production and is suitable for various substrates, such as coated paper, offset paper, and cardboard.
Its characteristics are flat surface of printed products, soft and natural colors, no obvious indentation, suitable for mass printing of various products. It has a wide range of application scenarios, including books and albums, posters and leaflets, packaging gift boxes, magazines and newspapers, corporate brochures, etc., and is the preferred process in the printing and packaging industry that balances quality and efficiency.
