濟(jì)南宣傳單頁印刷廠家在印刷宣傳冊(cè)等彩印怎樣防止印后常見故障？今日來為大伙兒解釋這個(gè)問題，讓我們一起來了解下吧！

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.恰當(dāng)挑選模切刀：模切刀要銳利、強(qiáng)度要高。對(duì)于不一樣薄厚的打印紙張應(yīng)當(dāng)挑選不一樣的模切刀。

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.恰當(dāng)挑選壓痕線與壓痕鋼線：高品質(zhì)的壓痕鋼線應(yīng)強(qiáng)度適度，可靠性強(qiáng)，刀片圓潤，弧形中中心對(duì)稱，高度、薄厚誤差小，規(guī)格型號(hào)齊備。

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.

魔切割刀的采用標(biāo)準(zhǔn)是：壓痕鋼線的薄厚不小于紙厚，高度相當(dāng)于模切刀頭高度減掉模切原材料薄厚，再減掉調(diào)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.

壓痕線的采用標(biāo)準(zhǔn)是：壓痕線的薄厚不小于紙厚，總寬相當(dāng)于紙厚的1.5倍再加上壓痕鋼線的薄厚。

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，模切版下紙墊過厚、模切工作壓力過大、壓痕模過厚、壓痕?？p窄等也易造成爆線難題。在模切磨紗印刷物時(shí)還要開展相對(duì)應(yīng)調(diào)節(jié)．并在模切全過程中立即壓痕?？p中堆積的紙粉和臟物等。

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.有效操縱開連點(diǎn)：連點(diǎn)實(shí)質(zhì)上是在模切刃口口位置給出一定總寬的口子，使模切后的紙箱和廢邊不散掉，有利于排廢。連點(diǎn)一般開在商品成形后不容易見到的隱秘處，而且要繞開線皮部位。

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.

假如迫不得已連點(diǎn)在成形后可以看到，則連點(diǎn)應(yīng)越低越好，不然排廢時(shí)連點(diǎn)處不容易分離出來，造成打印紙張撕壞及周邊墨層爆線。連點(diǎn)總寬；紙厚+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.科學(xué)安排模切時(shí)間：磨紗包裝印刷的金(銀)紙卡的模切應(yīng)在包裝印刷后盡快開展，避免墨膜在干躁過多的狀況下開展，以防止墨層爆線。

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.

總的來說，先模切壓痕品質(zhì)是危害印刷物品質(zhì)的關(guān)鍵緣故。模切刀和壓痕鋼線挑選不科學(xué)，錯(cuò)誤操作等全是造成墨層爆線的關(guān)鍵緣故，如模切刀遲緩等。還有什么問題就來我們網(wǎng)站http://shpjen.com.cn咨詢！

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.
