Traditional flexible edition with digital flexible version of the major difference, is producing digital gravure process, soft version of the surface layer of black adds a laser photoreceptor layer. Black film's main function is to replace the traditional flexible version in the process of making films. Traditional flexible version of making is the image data transfer to a phototypesetter, then making the flexible version of the film, and digital flexible version of the plate is will plate direct put on soft CTP platemaking machines version, image data will be transmitted to one laser device, a laser corrosion of the dark membrane, make its volatile effect, thus to plate surface formation to the images.
Then will the printing plate remove from platemaking machines, and then to exposure, enhancement. In addition to laser photographic dark membrane up block UV light outside the role, making digital soft version of UV exposure and when traditional soft plate exposure is the same the next development also and the traditional book the same. In the VU exposure and the developing process, every step of the purpose and function are the same, but there are some minor differences we need to pay attention to. The first thing to remember is to use a digital version of the soft produce the shape and the traditional outlets on the gravure shape node is totally different. So outlets have different values increase, and printing machine also need to adopt new technology to cooperate with accordingly.
A digital version of the site and the traditional soft soft version of the network outline, digital type of the network than the traditional gravure outlets outline more acute. It is these sharp outlets improve a digital version of the soft quality and performance, but exempt from film and imaging technology to ensure the accuracy of the consistency of the quality of plate, this in the control printing and the final print process is of Paramount importance. In addition to improve quality, more important is that we can through a digital, can control the flow in a printing shop.
What is the right digital flexo printing technology?
The right digital flexo printing technology needs a drum, the structure of laser imaging head, can accurately, repeatedly make black film volatile corrosion. Here KeLiAo ThermoFlex of heat can be god gravure direct platemaking machines to illustrate that it's leading of the laser head imaging, using a laser diode as laser light sources; The laser head have different types, according to the needs of the users, can be as high as 64 bouquets of laser, all flexo CTP suppliers are now tend to be more than the laser beam technology.
Why do all flexo CTP suppliers are now tends to be more than the laser light technology? The primary reason is because many a laser beam technology in quality, repeatability, production efficiency and reliability were strong advantage.
In order to get high quality, can repeat image, the ideal imaging system should have perfect mechanical stability. Mechanical stability and imaging of roller speed has a direct bearing, in order to obtain the same production efficiency, a laser beam, the greater the number of roller speed can be more slowly, so the more laser beam, the more beneficial to improve image quality and repeatability.
Image quality and repeatability with each of the laser beam is completely remove the ability of photographic dark membrane directly related. Laser imaging's main purpose is to ensure full get rid of dark membrane. Provide gaussian laser beams because the equipment with irregular energy distribution, so the accuracy and consistency imaging is restricted. KeLiAo heat of god gravure direct platemaking machines using bunch of laser diodes, using technology to provide the continuous energy distribution, so has high accuracy and imaging consistency.
