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 Chuangli printing 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 exhibition will be held concurrently with the 23rd Nanjing Advertising Exhibition, which will create a one-stop service for printing, packaging and advertising equipment. This exhibition will showcase partners for the company's new products, new technologies and new equipment in the Jiangsu region, expand the market for well-known brands that have entered Nanjing, create trade opportunities, and provide enterprises with a communication, negotiation, transaction and The best trading platform for cooperation.
