在印刷行业,后道工艺非常的重要,影响着成品的质量,所以要有一个很好的后道处理工艺,下面就由济南书刊杂志印刷厂家为大家简单介绍一下常见的后道工艺技术要点,希望对大家有所帮助!
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.横纹刀用于模切纸质材料,用它模切纸品,切口有镜面效果,顺滑,不生尘,横纹刀的刀锋稳定,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上光油如果油墨覆盖面积很小,则可考虑用UV油墨印色加上UV光油可以省加过底油这个过程。
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.糊盒问题避免糊盒时在其糊口黏合剂难渗透亮光油造成粘接不牢,可以采用局部印刷亮光油的方法。一是专门晒制一块印刷亮光油的印版或对拼 数不多的印版,可以反黏合处的纸舌所对应的橡皮布下的纸张衬垫局部割除,使那一部分的印刷压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.磨光处理注意不能用射光蓝(或红)墨印刷的印品进行磨光处理,因为磨光后墨层变色,会造成产品批量报废。

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.烫金版常识硅橡胶烫金版:复杂烫印,耐高温;铜锌版:只能制成平面凸文,制作时生成一氧化氮破坏环境;⑶树脂版:不耐高温,PP、PE无法使用;感光硅橡胶版:综合1、3耐高温,柔韧性好,适合于复杂曲面工件。
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、击凸一次完成工艺凸版的高度不能高于模切刀的高度,一般合压后击凸版的高度应与模切刀的高度相同。但450G以上厚纸板应分开来做。模切工艺直纹处理的模切刀用于模切胶质材料,因为胶质材料需要用更锋利的直纹刀来模切。
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.先烫后印工艺要求:定位十字线——在烫印的叼口和靠身部分加套准十字线;烫印压力以用手触摸没有明显的凹凸感为标准;烫印签样时应准备烫印胶片,把图案勾线(0.01mm线条),检查是否局部图案残缺;印刷前空压——把电化铝屑压掉,避免印刷油墨转移不上的现象;纸张要求表面强度高,白卡纸或玻璃卡纸注意反拉现象;烫印应用圆压圆或圆压平烫金机,因线接触压力较易调整;排版幅面不宜太大,拼版联数不易过多,以免造成印刷套准困难;烫印版一般采用腐蚀铜版或锌版,注意其平整度,最好用电雕版,并做一定的弧度,即中间高,周围低。
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.
