Traditional printing technology prepress process, making films is a very important aspect of high-quality film output relationship of the final print quality.
Film output film is produced, which uses the photosensitive material in the blue violet laser light irradiation or chemical reaction to form the image area and the principle of non-image area.
Offset and gravure industry sectors for film output has a high demand, the usual film output machine is in accordance with the requirements of these two industries manufacturing. But in the pad printing, screen printing, hot stamping industry, film output significantly lower accuracy requirements, the use of medium-precision film output enable printing and other printing products industry cycles significantly reduced.
Especially in some toy factory, product replacement fast, printing has high frequency content updates, use own film output machine will greatly enhance the content according to user requirements change the printing efficiency.
KC printing machinery company launched the PM-410FL film output machine with violet laser technology, specifically for printing and screen printing industry, to distinguish accuracy 3000DPI, used roll film output, widely for a variety of toy factory, electronics factory, and gift plants are used.
Laser imagesetter is a prepress processing equipment with relatively simple structure and low cost:

Working principle

Decompose the text and image information in the computer into dot matrix, then control the laser to scan on the photosensitive material, expose the photosensitive material to form a latent image, and then convert the latent image into visible text and image through development, fixing and other processes.

Structural composition

• Laser light source system: mostly use long-life semiconductor lasers, such as 635nm wavelength red laser diodes, which have the advantages of small size, low cost and long life.

• Scanning system: Commonly used is the laser polygonal mirror scanning capstan structure, through the rotation of the polygonal mirror, the laser beam is scanned on the photosensitive material.

• Film supply and collection system: equipped with independent film supply box and film collection box, which can accommodate a certain number of photosensitive films. The film supply box transports the film to the scanning area, and the film collection box collects the exposed film.

• Control system: connect to the computer, receive and analyze the graphic information sent by the computer, control the emission of the laser light source, the movement of the scanning system, and the action of the film supply and collection system.

Performance characteristics

• Easy operation: The interface is simple and intuitive. Operators can master the operation method after simple training and can quickly set up file output and operate the equipment.

• Moderate resolution: The film width is generally 405mm, the length is unlimited, and the resolution can meet the general printing platemaking needs.

• Slow film output speed: Compared with high-end equipment, the film output speed of simple laser typesetting machines is slower. For example, some equipment can output 1-3 sheets of film per second.

Application scenarios

Mainly used in small printing companies such as pad printing, silk screen printing, flexographic printing, offset printing, platemaking studios, advertising companies, etc., where the printing accuracy requirements are not extremely high and the business volume is relatively small. It can be used to make film films for printed materials such as leaflets, posters, business cards, and packaging boxes.
