在印刷行業,后道工藝非常的重要,影響著成品的質量,所以要有一個很好的后道處理工藝,下面就由濟南書刊乐天堂国际官网廠家為大家簡單介紹一下常見的后道工藝技術要點,希望對大家有所幫助!
In the printing industry, the back-end process is very important, affecting the quality of finished products, so there must be a good back-end process, the following by Jinan magazine printing manufacturers for you to briefly introduce the common back-end process and technical points, I hope to help you all!
1.橫紋刀用于模切紙質材料,用它模切紙品,切口有鏡面效果,順滑,不生塵,橫紋刀的刀鋒穩定,耐用。
1. The cross-cutting knife is used for die cutting paper materials. It is used for die cutting paper products. The incision has mirror effect. It is smooth and dust-free. The blade of the cross-cutting knife is stable and durable.
2.UV上光油如果油墨覆蓋面積很小,則可考慮用UV油墨印色加上UV光油可以省加過底油這個過程。
2. If the ink coverage area of UV polishing oil is very small, it can be considered that the process of printing with UV ink and UV polishing oil can save the addition of base oil.
3.糊盒問題避免糊盒時在其糊口黏合劑難滲透亮光油造成粘接不牢,可以采用局部印刷亮光油的方法。一是專門曬制一塊印刷亮光油的印版或對拼 數不多的印版,可以反黏合處的紙舌所對應的橡皮布下的紙張襯墊局部割除,使那一部分的印刷壓力不足以反亮光油印上。
3. To avoid the problem of paste box, it is difficult for paste box to penetrate the bright oil in its paste adhesive, so the method of local printing bright oil can be used. One is to specially make a printing plate with bright oil or a printing plate with a small number of pieces. The paper pad under the rubber cloth corresponding to the paper tongue at the anti-bonding position can be partially cut off, so that the printing pressure of that part is not enough to reflect the bright oil printing.
4.磨光處理注意不能用射光藍(或紅)墨印刷的印品進行磨光處理,因為磨光后墨層變色,會造成產品批量報廢。

4. The polishing process should not be carried out on the printed matter printed with Jet Blue (or red) ink, because the discoloration of the ink layer after polishing will result in mass scrap of the product.

5.燙金版常識硅橡膠燙金版:復雜燙印,耐高溫;銅鋅版:只能制成平面凸文,制作時生成一氧化氮破壞環境;⑶樹脂版:不耐高溫,PP、PE無法使用;感光硅橡膠版:綜合1、3耐高溫,柔韌性好,適合于復雜曲面工件。
5. Silicone rubber stamping plate: complex hot stamping, high temperature resistance; copper and zinc plate: can only be made into flat convex text, the production of nitric oxide damage the environment; _resin plate: high temperature resistance, PP, PE can not be used; photosensitive silicone rubber plate: comprehensive 1, 3 high temperature resistance, good flexibility, suitable for complex curved surface workpieces.
6.模切、擊凸一次完成工藝凸版的高度不能高于模切刀的高度,一般合壓后擊凸版的高度應與模切刀的高度相同。但450G以上厚紙板應分開來做。模切工藝直紋處理的模切刀用于模切膠質材料,因為膠質材料需要用更鋒利的直紋刀來模切。
6. The height of the die-cutting and punching process relief should not be higher than that of the die-cutting cutter. The height of the post-punching relief should be the same as that of the die-cutting cutter. But over 450G cardboard should be made separately. Die-cutting process The die-cutting knife with ruled treatment is used for die-cutting of colloidal materials, because colloidal materials need to be cut with a sharper ruled knife.
7.先燙后印工藝要求:定位十字線——在燙印的叼口和靠身部分加套準十字線;燙印壓力以用手觸摸沒有明顯的凹凸感為標準;燙印簽樣時應準備燙印膠片,把圖案勾線(0.01mm線條),檢查是否局部圖案殘缺;印刷前空壓——把電化鋁屑壓掉,避免印刷油墨轉移不上的現象;紙張要求表面強度高,白卡紙或玻璃卡紙注意反拉現象;燙印應用圓壓圓或圓壓平燙金機,因線接觸壓力較易調整;排版幅面不宜太大,拼版聯數不易過多,以免造成印刷套準困難;燙印版一般采用腐蝕銅版或鋅版,注意其平整度,最好用電雕版,并做一定的弧度,即中間高,周圍低。
7. Process requirements of hot stamping followed by printing: positioning cross-line-adding quasi-cross-line in the mouth and body parts of hot stamping; hot stamping pressure is based on the fact that there is no obvious concave-convex feeling when touching by hand; hot stamping sample should be prepared with hot stamping film, marking the pattern (0.01 mm lines), checking whether the local pattern is incomplete; pre-press-press-press-press-press-press the electrolytic aluminium chip to avoid printing ink transfer. The phenomena above; paper requires high surface strength, white cardboard or glass cardboard pay attention to pullback phenomenon; hot stamping using circular or circular calendering machine, due to the line contact pressure is easy to adjust; typesetting width should not be too large, the number of assembly is not too many, so as to avoid printing registration difficulties; hot stamping plate generally uses corroded copper or zinc plate, pay attention to its smoothness, the best is to use electric engraving plate, and do it. Certain radian, that is, high in the middle, low around.
