Why do I have to cut the edges of the paper before it is cut?
Release time：2025-01-16
Printing plant paper cutter before opening, always cut off the edge of the full-open paper a little, and then cut in accordance with the target size, this is why?
Improve paper neatness
Trimming Rough Edges
During production and transportation, the edges of paper may become rough, uneven, stained, scratched, weak, etc., due to friction, folding, etc., resulting in “rough edges”. Edge cutting can effectively remove these burrs and make the paper edges smooth and neat.
Ensure Consistency
Untidy edges may lead to inaccurate paper sizes during the opening process, affecting subsequent use; and by cutting the edges, you can ensure that the size and shape of each sheet remains consistent, facilitating the smoothness of subsequent printing, cutting, post-press processing and other processes.
Improvement of printing quality
Avoiding Inaccurate Color Registration
Uneven paper edges can lead to poor color registration during the printing process, affecting the quality of the printed product. Cutting the edges of the paper ensures that the edges of the paper are flat, thus improving the color registration accuracy of the print.
Reducing confetti interference
For coated papers (such as coated papers), the coated layer at the edges may drop some debris during transportation. This debris may fly onto the printing surface during the printing process, causing quality problems such as white spots. Cutting the edges minimizes this confetti interference.
Various other benefits
Reducing waste
The neat, smooth edges of the cut paper are more conducive to machine gripping and transport. Removing imperfections and excess from the edges by cutting the edges optimizes material utilization and thus reduces waste.
Size Reservation
Since the original size of the paper will be somewhat larger than the actual specifications, cutting the edges removes the blank portion of the edges while preserving these non-printed areas, ensuring that the final product is dimensionally correct.
Extra Profit
The cut edges are not just thrown away, but can be sold for money as waste paper, and because there is no ink attached, the price is a little higher than the rest of the waste paper from the printing plant, and the accumulation of small amounts can also help to reduce production costs.
