Curved Screen Printing Industry Has A Long Way To Go

Curved Screen Printing Industry Has A Long Way To Go      Curved screen printing refers to screen printing on round shaped surfaces, such as various chemical bottles, medicine bottles, wine bottles, etc. most of them are cylindrical or almost cylindrical surfaces (the arc surface of flat bottles belongs to cylindrical surfaces), and there are few conical and spherical surfaces. Curved Screen Printing Industry Has A Long Way To Go       No matter what kind of surface, there is only one printing principle, that is, the silk screen printing surface should make a pure rolling motion with the screen. During the rolling, the surface is tangent to the screen to deal with the falling point of the rubber scraper, and its extension line always points to the center of the circle.Curved Screen Printing Industry Has A Long Way To Go       The design of curved screen printing machine is also based on this principle, which is generally driven by the toothed transmission of gear and rac […]
