The above items are common inspection items of hardcover book printing quality, which can be carried out by combining manual inspection with machine vision inspection to improve the accuracy and efficiency of inspection. At the same time, in the printing quality inspection, we should also protect the integrity and safety of printed matter to avoid damage to printed matter.
