What are the special processes of printing industry? Printing technology itself is a high-tech process, with the continuous development and improvement of modernization, printing technology of course also needs to move forward steadily. Printing technology should not only go ahead in the direction of environmental protection, but also in the direction of digitalization and informatization, which is not an easy task. Printing, which used to be an old term, will be a technical field that requires continuous and long-term learning for every relevant practitioner today.

现在印刷厂小编我来简单介绍下印刷厂的特殊工艺。我想介绍的是珠光印刷，它是使用珠光油墨的一种特殊印刷技术。由于珠光油墨有着蚌珠天然光泽，使包装印刷品展现出犹如珠光宝气般的缤纷色彩，显得典雅。珠光印刷工艺可采用平版印刷、凸版印刷、凹版印刷或柔性版印刷方式，也可用丝网印刷方式。由于印刷方式不同应根据工艺的特点，合理选用不同颜料粒径范围的珠光油墨，如凸版工艺可选用粒径粗点的珠光颜料的油墨。珠光印刷的承印物以表面光泽性能好、平滑度高，可以呈现出印刷品的良好效果。日常生活中我们可以见到些可以散发的芳香气味的印刷品，诸如名片、贺卡以及包装产品，这种印刷品就是采用香料油墨进行印刷的。这种工艺可采用将香料直接加入油墨中，用凸印、柔性版和胶印机印刷，方法简单，但香味难以持久保存。现在多采用以香料封入胶囊内的香料油墨进行印刷。这种印刷厂方式因香料是由微胶囊摩擦破裂而徐徐散发出芳香味，能持久保存。是不是很神奇呢？后我再来说说贴花印刷，它是采用间接转移方式来实现的。

Now let me briefly introduce the special technology of the printing plant. First of all, I would like to introduce pearlescent printing, which is a special printing technology using pearlescent ink. Because the pearlescent ink has the natural luster of mussel pearl, the packaging printing products show colorful colors like jewelry gas, which appears noble and elegant. Pearl printing process can be lithographic printing, relief printing, gravure printing or flexographic printing, or screen printing. Because different printing methods should be based on the characteristics of the process, reasonable selection of pearlescent inks with different particle sizes of pigments, such as relief printing process can choose pearlescent inks with coarse particle sizes. Pearlescent prints have good surface gloss and smoothness, which can show a good effect of printing. In our daily life, we can see some aromatic prints, such as business cards, greeting cards and packaging products, which are printed with perfume ink. In this process, spices can be directly added to the ink and printed by embossing, flexographic and offset press. The method is simple, but the fragrance is difficult to preserve for a long time. Nowadays, perfume inks sealed in capsules are mostly used for printing. This way of printing, because the perfume is rubbed and broken by microcapsules, emits fragrance slowly and can be preserved for a long time. Isn't it amazing? Finally, let me talk about Decal printing, which is achieved by indirect transfer.

先是用平印工艺将图案印在涂胶纸或塑料薄膜上，然后将这种贴花印刷的成品贴在所要装饰的物体表面，利用树胶的水溶性，经用水浸泡使树胶溶解，随即把纸或塑料薄膜撕揭下来，图文即被转移到物体表面。印刷工艺应用的不同会营造出不同的效果，这些加工在提升设计作品创意和艺术价值方面起到了重要的作用，会使印刷品在质感上产生鲜明的对比，会更加富有表现力和独特的个性。例如烫箔能够增加视觉上的冲击力；上光能带来明亮的光感效果；模切工艺的应用使作品的结构丰富有层次，增加阅读的趣味感，增强客户与印刷品的互动性。

Firstly, the pattern is printed on the coated paper or plastic film by lithographic printing process, and then the finished product of this decal printing is pasted on the surface of the object to be decorated. The water solubility of the gum is used to dissolve the gum by soaking in water. Then the paper or plastic film is torn off, and the pictures and texts are transferred to the surface of the object. Different application of printing technology will create different effects. These processes play an important role in improving the creativity and artistic value of design works. They will make a sharp contrast in the texture of printed products, and will be more expressive and unique personality. For example, foil ironing can increase the visual impact; polishing can bring a bright light effect; die-cutting technology makes the structure of the work rich and hierarchical, increase the interest of reading, and enhance the interaction between customers and printed matter.
