Board Book Printing die-cutting products, in addition to paper hair, paper dust, explosion line and mark line unclear is also a frequent problem, because of many reasons, only prior prevention, will be possible problems in the bud.


(1)    Most of the paper used in the board book printing is about 350 g/m2 of gray-bottom white board paper or white card paper, because of climate or other reasons, the paper is easily brittle due to the decrease of water content, resulting in die-cutting indentation when the line can not be perfectly reproduced, pressure on the burst line, light mark line is not raised and powerless. To this end, before die-cutting can be humidifier to increase the water content of paper, so that the paper slightly flexible after the machine die-cutting.


(2)     If the paper is thicker and the equipment is not adjusted in operation, it is easy to produce explosive or mark lines, and reasonable indentation steel lines should be selected according to the actual paper and mark lines.



(3)     If the lining under the steel plate is not reasonable for board book printing, the die cutting pressure will change, and the explosive or mark line will appear on the product.


(4)     If the bottom template is too thick or unreasonable sponge rubber strip is selected, the indentation line width is different and explosive line, the bottom template and sponge rubber strip of the appropriate thickness should be selected, and the indentation line width should be adjusted appropriately.



(5) If the paper powder dropped from the incision is accumulated in the slot, the explosive line or mark line is not clear, and the operator should strengthen self-examination to remove the paper powder and foreign body in time.
