济南宣传单页印刷厂家在印刷宣传册等彩印怎样防止印后常见故障？今日来为大伙儿解释这个问题，让我们一起来了解下吧！
How can Jinan promotional leaflet printing manufacturers prevent common malfunctions after printing brochures and other color prints? Today, let's explain this issue to everyone, let's get to know together!
1.恰当挑选模切刀：模切刀要锐利、强度要高。对于不一样薄厚的打印纸张应当挑选不一样的模切刀。
1. Proper selection of die-cutting knives: die-cutting knives should be sharp and have high strength. For printing paper with different thicknesses, different die-cutting knives should be selected.
2.恰当挑选压痕线与压痕钢线：高品质的压痕钢线应强度适度，可靠性强，刀片圆润，弧形中中心对称，高度、薄厚误差小，规格型号齐备。
2. Proper selection of indentation lines and indentation steel wires: High quality indentation steel wires should have moderate strength, strong reliability, rounded blades, symmetrical center in the arc, small height and thickness errors, and complete specifications and models.
魔切割刀的采用标准是：压痕钢线的薄厚不小于纸厚，高度相当于模切刀头高度减掉模切原材料薄厚，再减掉调整值0.05～0.11mm。
The standard for using magic cutting knives is that the thickness of the indentation steel wire is not less than the thickness of the paper, and the height is equivalent to the height of the die cutting blade minus the thickness of the die cutting raw material, and then minus the adjustment value of 0.05-0.11mm.
压痕线的采用标准是：压痕线的薄厚不小于纸厚，总宽相当于纸厚的1.5倍再加上压痕钢线的薄厚。
The standard for using indentation lines is that the thickness of the indentation line is not less than the thickness of the paper, and the total width is 1.5 times the thickness of the paper, plus the thickness of the indentation steel line.
除此之外，模切版下纸垫过厚、模切工作压力过大、压痕模过厚、压痕模缝窄等也易造成爆线难题。在模切磨纱印刷物时还要开展相对应调节．并在模切全过程中立即压痕模缝中堆积的纸粉和脏物等。
In addition, excessive thickness of the paper pad under the die-cutting plate, excessive working pressure during die-cutting, excessive thickness of the indentation die, and narrow gaps in the indentation die can also cause problems with thread breakage. When die-cutting and grinding printed materials, corresponding adjustments should also be carried out. During the entire die-cutting process, the accumulated paper powder and dirt in the indentation mold seam should be immediately removed.
3.有效操纵开连点：连点实质上是在模切刃口口位置给出一定总宽的口子，使模切后的纸箱和废边不散掉，有利于排废。连点一般开在商品成形后不容易见到的隐秘处，而且要绕开线皮部位。
3. Effective control of connection points: Connection points essentially provide a certain overall width of the opening at the die cutting edge position, so that the cardboard boxes and waste edges after die cutting do not scatter, which is conducive to waste disposal. The connecting point is usually opened in a hidden area that is not easily visible after the product is formed, and the wire skin part needs to be wound.
假如迫不得已连点在成形后可以看到，则连点应越低越好，不然排废时连点处不容易分离出来，造成打印纸张撕坏及周边墨层爆线。连点总宽；纸厚+0.20毫米。
If it is necessary to see the connection point after forming, the lower the connection point should be, otherwise it is difficult to separate the connection point during waste discharge, resulting in torn printing paper and explosive lines in the surrounding ink layer. Total width of connecting points; Paper thickness+0.20mm.
4.科学安排模切時间：磨纱包装印刷的金(银)纸卡的模切应在包装印刷后尽快开展，避免墨膜在干躁过多的状况下开展，以防止墨层爆线。
4. Scientifically arrange the die-cutting time: The die-cutting of gold (silver) paper cards for ground yarn packaging and printing should be carried out as soon as possible after packaging and printing, to avoid excessive drying of the ink film and prevent the ink layer from exploding.
Overall, the quality of die-cutting and indentation is the key factor that endangers the quality of printed materials. The unscientific selection and incorrect operation of die cutting knives and indentation steel wires are all the key reasons for the ink layer exploding, such as slow die cutting knives.
