| 胶版印刷 Offset printing 珠光纸主要是体现纸张珠光的华丽效果，如果印刷油墨的面积很大，一则体现不出纸张的珠光效果，二则纸张的珠光效果通过墨层已经大大削弱。所以，我们在设计制版时应根据珠光纸的特点尽量避免大面积的实地图案印刷。一般设计一些简单的线条、图案、文字，既可以突出包装内容的重点，又可以显示出纸张的华丽效果。 Pearlescent paper mainly reflects the gorgeous effect of paper pearlescent, if the printing ink area is very large, one can not reflect the paper pearlescent effect, the paper pearlescent effect has been greatly weakened through the ink layer. Therefore, when we design and plate, we should try to avoid large area of real map printing according to the characteristics of Pearl paper. General design of some simple lines, patterns, text, not only can highlight the focus of packaging content, but also can show the gorgeous effect of paper. 珠光纸的珠光颗粒容易破碎，半成品经不起反复的转序、摩擦，所以生产的工艺路线应尽量短一些，取消一些可有可无的工艺环节，特别是那些手工参与较多的环节。能一次印刷完成的不用两次，能用胶印印刷的不用丝网印刷，能连机上光的不脱机上光，当然可以不上光的坚决不上光，因为上光会大大削弱珠光纸的珠光效果。 Pearlescent paper particles are easy to break, semi-finished products can not withstand repeated order, friction, so the production process should be as short as possible, to cancel some of the process links that are not necessary, especially those involved in more manual links. Can be printed without two times, can be offset printing without screen printing, can be connected to the machine without off-line polishing, of course, can not be polished steadfastly never polishing, because polishing will greatly weaken the pearlescent effect of pearlescent paper. 油墨印刷 Ink printing UV印刷是采用紫外线干燥，印刷时每一印刷单元都带有紫外干燥装置。UV油墨经过干燥装置时在光引发基团的引发下干燥时间很短，可以说是瞬间干燥，这样在进入下一印刷单元或是收料环节已经完全干燥。我们可以采取加大墨量、降低油墨黏度等方法来提高油墨在珠光纸表面的着墨率，同时油墨的叠印也是一种“干-干”叠合的方式，可以大大提高叠印率。 UV printing is made by ultraviolet drying. When printing, each printing unit has a UV drying device. UV ink drying time is very short when it passes through the drying device, it can be said to be instantaneous drying, so in the next printing unit or the receiving link has been completely dry. We can increase the amount of ink, reduce ink viscosity and other methods to improve the ink on the surface of pearlescent paper, and ink overlay is also a "dry-dry" overlap, can greatly improve the overlap rate. |
