Laser phototypesetter for printing plants:

Working principle

Laser phototypesetter outputs graphic information in the computer to film by laser scanning. It controls the intensity and scanning path of the laser beam to expose the photosensitive material on the film. After subsequent processing such as development, it forms a film that can be used for printing plate making.

Features

• High cost performance:

• This laser phototypesetter is relatively reasonably priced and can provide high-quality output that meets basic needs. It achieves a good balance between cost and performance, and is a good choice for users with limited budgets but who need high-quality printing plate making. For example, small printing shops can obtain typesetting equipment that can meet daily business at a lower cost.

• Darkroom operation:

• Due to the photosensitive characteristics of film, light may interfere with the film during the laser typesetting process, so it needs to be operated in a darkroom environment. Darkroom operation can ensure the accuracy of the film exposure process, avoid unnecessary light from exposing the film, and enable the output film to accurately reflect the graphic information in the computer.

• Easy maintenance:

• The equipment may be designed with a simple and easy-to-understand structure and easy-to-replace parts. For example, its internal optical system may be relatively easy to clean and calibrate, and the mechanical parts are also easy to disassemble and repair. For operators, after simple training, they can perform daily maintenance work, such as cleaning the lens and replacing consumables, reducing downtime and maintenance costs caused by equipment failure.

• LCD interface:

• The LCD interface makes operation more intuitive and convenient. Users can view the status parameters of the equipment, such as laser power, scanning speed, film remaining, etc., through the LCD screen. At the same time, various operation settings can be easily performed on the LCD interface, such as adjusting graphic layout parameters, selecting output resolution, etc., which greatly improves the convenience and efficiency of operation.

    Most printing processes require printing plates, especially in the field of special printing, such as pad printing, screen printing, hot stamping, flexo printing, offset printing, and gravure printing. Some printing processes with higher technical barriers are developing towards computer direct platemaking technology (CTP), that is, using computer control to directly output the design draft stored in the computer to the printing plate to form a printing plate. Offset printing, flexo printing, and screen printing are relatively mature. Some printing processes with lower technical barriers still follow the traditional platemaking process. First, the image and text are output to the platemaking film, and then the platemaking film is used to cover the printing plate to make the printing plate. Pad printing, screen printing, and hot stamping still retain this process. The platemaking film becomes a film, which is formed by coating a photosensitive layer on a PET film. The transparent area of ​​the platemaking film will transmit ultraviolet light, and the non-transparent area will block light. The photosensitive layer will solidify in the area that transmits ultraviolet light, and the photosensitive layer will not solidify in the area that does not transmit ultraviolet light, and will be washed away during development and washing.
Most pad printers, screen printers, and hot stamping machine operators are small-scale investors with meager profits, and may not be willing to buy expensive laser phototypesetters. However, the KC series laser phototypesetters are inexpensive, have moderate accuracy, and are easy to operate. They usually recover their costs in about three months. If you are engaged in pad printers, screen printers, and hot stamping machine processing business, or provide film output and plate making business for other printing factories, you can consider the KC brand laser phototypesetter.
