The precision plate-printing machine is fully automatic. Each time the plate is exhausted, exposed and exhausted, it is automatically completed. It is easy to operate. It is equipped with a precise calculation of the light quantity control device. It uses the energy of absorbing light instead of relying solely on time to control the screen. Exposure, to ensure the accuracy of the exposure, fundamentally eliminate the network cable errors caused by insufficient voltage, lamp electrification, unstable lamp start, etc. This article will introduce you to the transfer of the plate machine.
The working principle of the printing machine: the film and PS version are closely attached, and then exposed to ultraviolet light. The quality of the sounding version has two main points: the 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 (such as film) and PS version fit.
The printing machine occupies an extremely important position in the prepress equipment, and its performance directly affects the quality of the plate making, and its maintenance plays a decisive role in the printing production process. If the correct selection, proper maintenance and timely maintenance of the required printing machine can not only improve the service life of the printing machine, but also improve the quality of the printing plate. The temperature rise of the working glass surface of the plate printing machine should be no more than 20 °C. Detection method: the exposure light source is placed in the normal working position, and the surface temperature of the working glass is measured by a point thermometer having a division value of not less than 0.5 °C.
The printing machine has the advantages of uniform illumination intensity, stable light quantity control, stable source wavelength, 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.
