It is very important to do a good job in paper cutting process management.

Paper cutting is one of the important aspects of printing . In actual work, whether it is cutting paper for printing, binding materials, or printing finished products after cutting and binding, cutting quality and efficiency are important to ensure the quality of semi-finished products and printed products. Here, the author summarizes the work requirements and management methods of the paper cutting process, and shares it with peers.

Printing requirements for paper cutting quality

1. Paper size accuracy requirements

For the same batch of work, the paper size should be the same, which is also the need for the paper to be separated normally during the printing process. Especially when printing thick cardboard, the paper-shielding steel used in the Feida part is harder, if it is used in the same batch of work. The size of the cardboard is inconsistent and it is easy to cause paper feed failure. When the paper is long, the paper separation nozzle cannot suck the first paper from the paper stopper and the air is loose. When the paper is short, the paper stopper does not reach into the paper pile and scrapes the paper. The second sheet of paper sucked up by the mouth appears double-fold. For the paper that is flipped back and forth, because the front and back sides of the paper are printed differently, the size of the paper used for the same batch of work is required to be the same, otherwise the front and back patterns will be misaligned on the paper. .

2. The front edge and side gauge sides are vertical

The front side of the paper and the side of the side of the paper should be vertical. Otherwise, when the front side of the paper and the front positioning board are in line contact, the side and side positioning boards are in point contact, which is prone to contact deformation and overprinting. Not allowed. Figure 1 shows the paper with the front and side edges of the paper not perpendicular.

3. The incision should be neat and free of burrs

When the cutter is not sharp enough, the paper is prone to burrs. The burrs of the burrs are easily peeled off and adhered to the blanket during the printing process, which affects the printing quality, and the burrs at the nips easily affect the normal detection of the tamping detection mechanism and cause downtime.

Printing requirements for paper cutting quality

Strictly follow the specific instructions of the work instructions on the cutting process, cultivate good habits of safe and civilized production, and timely check equipment, motor, knife edge, switch and brake sensitivity.

Pay special attention to the cutting angle when cutting. It must be vertical. The size of each stack of paper should be consistent. The stack of paper is straight and straight, the cuts are neat, there are no knife flowers, broken mouths, slivers, roads and fluffing. It should be cut through, not dirty, not broken.

Ensure the quality of the cut, the size of the material and the size of the finished product are accurate. After the finished paper is cut, it should be stacked separately according to different work pieces, and the name of the print or the number of the printed order should be marked to avoid confusion and be sent to the machine on time to ensure the printing time.

When handing over to the Materials Section, carefully count the number of receipts.
