When the flexible plate is placed on the front side of the plate making machine, in order to ensure the quality of the film and the flexographic printing surface, the plate making machine is equipped with a vacuum pump to vacuum, and the side of the film required to be close to the flexo must be rough (matte). This can prevent air bubbles from remaining between the film and the flexo plate and affect the quality of the flexographic printing surface. The bead used for the pressure film and the flexographic edge should also be indented and can be used for lateral air conduction. In addition, there are specific requirements for the blackness and transparency of the film. This article will introduce you why the flexo press has no electric eye.
The flexo press machine personnel must carry out a comprehensive inspection of the equipment, repair, lubrication, commissioning, wiping, and wait until the workshop is inspected before it can start production next time. At the end of each month, concentrate the force on the equipment for thorough maintenance.
From the material and process of the flexo press, whether the machine structure is a uniform material, whether the main parts are made of special technology, our screen printing equipment is made of aluminum, aluminum and other aluminum materials, no one is used. The iron is easy to rust, the whole body is sprayed and sprayed, and a protective film is added to the whole body.
With the continuous development of printing technology, the flexographic printing line has no longer adhered to a single printing method, and has begun to transform into a diversified processing method that combines various printing processes and post-press processing. There are many successful cases in which a variety of processing methods such as gravure printing, screen printing, cold stamping, embossing, die cutting, etc. are added to a flexo printing machine.
At the time of plate making, it is necessary to master different exposure times to ensure the quality of the same plate and the field part. The difference between the image portion of the network cable and the solid portion is mainly due to the different depth of corrosion. In order to "stay" in the process of brushing the printing plate, the part of the wire needs to have a strong foundation, so the corrosion depth is shallower. Different corrosion depths can be obtained with different back exposure times by masking the local method. The front exposure time should also be done in a similar way, but it is said that the current flexographic plate manufacturer has introduced a new type of flexible plate, regardless of whether the printed part is a cable or a field, this plate only needs a uniform front exposure. Time, avoiding the trouble of multiple exposures, making flexo plate making more convenient
