Sheet-fed gravure printing machine experience exchange

Whether the mouthpiece is as small as possible The size of the paper mouthwash has always been a focus of the printing industry's technics department. He is concerned with the reduction of costs and the cooperation of the subsequent processes. Taking Chen Henry as an example, the minimum mouthpiece promised in the technical parameters of product samples is 15mm, but it faces challenges in production practice.
For example, in Yichang Shanxia Color Printing Factory, in the hard-packed “Green Three Gorges” field, if the cornice is less than 18mm, it will always be uneven and accompanied by an ink stick. According to the experience of other printing companies, it is not ideal if the tape is taped at the side of the mouth, or the rubber is cut at the mouth of the mouth to make it shallow, so as to increase the stiffness of the mouth.
The problem of gargle is particularly prominent only when large areas of the field are to be brushed. Small areas of graphics and text can be adjusted down to 12mm, but the promise of technical data must be left to the outside world. In the description, the minimum opening is 20mm.
