Three principles
1. Water oil incompatibility
The so-called similarity and compatibility principle in chemistry determines that the molecular polarity between water molecules with mild polarity is different from that of non-polar oil molecules, resulting in the inability to attract and dissolve between water and oil. The existence of this rule makes it possible to use water in plane printing plates to distinguish between pictures and blank parts.
2. Selective surface adsorption
According to the different surface tension, it can adsorb different substances, which also makes it possible for the separation of pictures and texts in offset lithography.
3. Dot image
Because the offset printing plate is flat, it can not rely on the thickness of the ink to express the graphic level on the printed matter, but by dividing the different levels into very small dot units that cannot be detected by the naked eye, we can effectively show a rich image level.
