Printing Iron Technology Development (in)

Because of the presence of rose spots, lack of precise expression of the rough texture, easy-to-hit mesh, easy-to-level, and tonal levels, it is difficult to express super-color gamut in terms of bright tone and solid color. Therefore, traditional tinplate printing is difficult to reproduce the original image. Bright colors, vivid levels and sharpness cannot adapt to the growing demand for high-fidelity printing.

Needs are the source of creation. In order to truly reproduce the original image appearance, a high-definition, wide-gamut high-fidelity metal printing technology came into being.
In the late 1990s, Panton in the United States, VISU in the Netherlands, LTG in the United Kingdom at the beginning of the new century, B+K in Germany, Greo in Canada, and Xpose in Switzerland! , COFCO, etc. have successively developed high-fidelity color printing technology with high-definition, high-image-level copying effects and expanded color gamut. This technique is a color reproduction technique that is highly realistic with the original, also known as the fourth-generation printing technology.
The core of the fourth-generation printing technology is the use of computer information systems and the latest results of image processing, and the use of modern ink technology to achieve high-definition and wide-gamut high-fidelity printing iron.
Normally, printing using an amplitude modulation network of 200 Lpi or more and frequency modulation of 2540 dpi and a dot size of 2×2 or less is called high definition printing. The area of ​​350 lines is one quarter of the area of ​​175 lines. Obviously, the finer lines can more clearly express the details in the image, so that the visual clarity is greatly improved.
