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.

現在印刷廠小編我來簡單介紹下印刷廠的特殊工藝。我想介紹的是珠光印刷，它是使用珠光油墨的一種特殊印刷技術。由于珠光油墨有著蚌珠天然光澤，使包裝印刷品展現出猶如珠光寶氣般的繽紛色彩，顯得典雅。珠光印刷工藝可采用平版印刷、凸版印刷、凹版印刷或柔性版印刷方式，也可用絲網印刷方式。由于印刷方式不同應根據工藝的特點，合理選用不同顏料粒徑范圍的珠光油墨，如凸版工藝可選用粒徑粗點的珠光顏料的油墨。珠光印刷的承印物以表面光澤性能好、平滑度高，可以呈現出印刷品的良好效果。日常生活中我們可以見到些可以散發的芳香氣味的印刷品，諸如名片、賀卡以及包裝產品，這種印刷品就是采用香料油墨進行印刷的。這種工藝可采用將香料直接加入油墨中，用凸印、柔性版和膠印機印刷，方法簡單，但香味難以持久保存?，F在多采用以香料封入膠囊內的香料油墨進行印刷。這種印刷廠方式因香料是由微膠囊摩擦破裂而徐徐散發出芳香味，能持久保存。是不是很神奇呢？后我再來說說貼花印刷，它是采用間接轉移方式來實現的。

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.

先是用平印工藝將圖案印在涂膠紙或塑料薄膜上，然后將這種貼花印刷的成品貼在所要裝飾的物體表面，利用樹膠的水溶性，經用水浸泡使樹膠溶解，隨即把紙或塑料薄膜撕揭下來，圖文即被轉移到物體表面。印刷工藝應用的不同會營造出不同的效果，這些加工在提升設計作品創意和藝術價值方面起到了重要的作用，會使印刷品在質感上產生鮮明的對比，會更加富有表現力和獨特的個性。例如燙箔能夠增加視覺上的沖擊力；上光能帶來明亮的光感效果；模切工藝的應用使作品的結構豐富有層次，增加閱讀的趣味感，增強客戶與印刷品的互動性。

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.
