Resin plate printing machine

The printing machine is a contact exposure imaging device for making printing plates. The pressure (including atmospheric pressure and mechanical pressure) is used to make the original plate and the photosensitive plate closely fit, so that the image on the original plate can be accurately dried by photochemical reaction. Made on the photosensitive plate. The printing machine is mainly composed of a light source device, an exposure room, a vacuum chamber, an electric part, a machine base, etc. This article will introduce you to the resin plate printing machine.

The working principle of the printing machine is simple, easy to operate, and the pressure is applied to make the original plate and the photosensitive plate closely fit, so that the image on the original plate can be accurately dried on the photosensitive plate by photochemical reaction. The printing machine is mainly composed of a light source device, an exposure chamber, a vacuum chamber, an electric appliance part, a machine base and the like.

The working principle of the printing machine is to closely match the film and the PS plate, and then expose it with ultraviolet light. There are two main reasons for the quality of the sounding version: vacuum, the closeness of the film and the PS version. The source of light, the wavelength of the ultraviolet light is within a certain range, as much as possible "pure". The closeness of the original and PS versions.

The blanket is one of the main sealing systems of the printing machine, and its performance directly affects the quality of the printing plate. When you usually put the PS version on the top, you should take it lightly to avoid scratching the edge of the PS plate and affecting the pumping effect.

The printing machine has the advantages of uniform illumination intensity, stable light quantity control, stable wavelength of light source, high vacuuming, long lamp life, etc. It is suitable for screen exposure of high-precision lines, dots and high-density network cables. In the above, the computer simulation test was adopted, the best angle was selected, and the imported reflective material from Germany was selected, and the light intensity was uniform.
