What are the advantages of winch and drum imagesetters?

Phototypesetting machine is one of the printing equipments, but it is divided into various forms according to the type of structure. For example, there are common winch type, drum type, etc. This article focuses on the advantages of the winch type and the drum type phototypesetting machine. ?


Advantages of the winch image picker:

The winch type uses the drum conveying technology, so there is no limit to the length of the image forming film, and the drum type device has a limitation on the length and width of the film. This allows the user of the winch type imagesetter to perform the arrangement of the oversized film.


The winch type phototyper can adjust the size of the film on the drum to be as small as a stamp, and as large as a large picture. The drum type phototyper is limited, allowing only the photo size and the maximum image size to be larger or smaller. The film size. Moreover, there are sometimes minimum size restrictions, which makes the printing of small prints inefficient and wasteful. In addition, the winch type does not require a long drum loading time, which makes the operation faster and easier. .


Advantages of the drum type photo-aligning machine:

Compared to drum-type equipment, the winch-type equipment drum transfer technology is designed to be flexible and user-friendly. But it is also the main reason for its shortcomings in quality and positioning.


The winch-type device uses a roller and a tension guide to lay the film on the glass plate. When the film moves, it is prone to off-track phenomenon, and sometimes there is stretching. When the film is too fast or too slow, dots with different degrees of tension often appear on the film, which causes the image dots to expand or contract.


A similar problem does not occur with the roller unit. The winch-type device does not replicate the film edge dots as the drum-type device, because the most accurate imaging point of the winch device is at the center of the film, and the laser can be imaged at a 90-degree angle. The edge of the film is scanned at an angle of 45 degrees, causing the dots to lengthen. When the roller technology is used, the film does not move and the laser moves on the film surface, so each dot is accurately exposed at a 90 degree angle.
