The skills of transferring ink to the surface of paper, fabric, leather and other materials through plate making, ink application, pressure and other processes of original manuscripts, such as text, pictures and photographs, to copy the content of original manuscripts in batches. It's called printing. There are many ways of printing: traditional offset printing, screen printing, digital printing and so on.

　　印刷工藝也可說是視覺、觸覺信息印刷仿制的全部過程，包含印前、印刷、印後加工和發送等。是一門集攝影，美術，工藝，化學，電子，電腦軟體、硬體科技，再加的考 量的雜亂和考驗的一門技能。即通過統籌、攝影、文字處理和美術設計、修改、分色、制版、印刷、印後成型加工按需求批量仿制美術、文字、圖畫的技能。

　　Printing process can also be said to be the whole process of visual and tactile information printing imitation, including pre-press, printing, post-press processing and sending. Is a collection of photography, art, technology, chemistry, electronics, computer software, hardware technology, plus environmental considerations of chaos and testing a super skill. That is, through overall planning, photography, word processing and art design, modification, color separation, plate-making, printing, post-press shaping processing, batch imitation of art, text, graphics skills according to demand.

　　印刷，作為一種圖象與文字仿制的技能，其社會含義在于它在仿制文字與圖象的同時記錄和傳播著相應的歷史文化，因此，早呈現印刷技能的 必定是人類文明的古國。印刷作為一門用來仿制的實用技能是人創造的，咱們所熟知的印章便是它的前期雛形。印章在我國歷史上呈現的很早，約在殷代即 已經有大量由金屬、石、陶、骨等制作的印章。前期的印章多為陰文，即文字凹于印面，后來又呈現了陰文印章，即文字凸出于印面，印章在歷史上首要的運用功用 是作為記號或符號的證明，尚不是以仿制為首要目的工藝方式，可是簡略的印章中包含了仿制技能中凸版及凹版的深入原理，關于印刷技能的創造在印的觀念上以十分重要的啟迪。

　　Printing, as a skill of image and text imitation, its social meaning lies in that it records and disseminates the corresponding history and culture while copying words and images. Therefore, the country that first presents printing skills must be the ancient country of human civilization. Printing, as a practical skill for imitation, was created by the Chinese. The seal we know well is its early embryonic form. Seals appeared very early in China's history. There were many seals made of metal, stone, pottery, bone and so on in the Yin Dynasty. Previous seals are mostly in the form of shades, i.e. letters are concave on the surface, and then the shades are presented. That is to say, letters are protruded from the surface. The primary function of seals in history is to prove signs or symbols. It is not yet a process with imitation as its primary purpose. However, the simple seals contain in-depth principles of relief and gravure in imitation skills, and the creation of printing skills lies in the creation of printing skills. The idea of India is very important.

　　雖然組合印刷可以發揮各種印刷方式的長處，但組合印刷現在仍處于發展初期，因此在操作過程中需求留意。不同的印刷工藝所運用的油墨組分不同，或許存在不兼容的現象，因此在組合印刷中，印刷之前需求對油墨進行兼容性測試。

　　Although combinatorial printing can give full play to the advantages of various printing methods, combinatorial printing is still in the early stage of development, so attention should be paid to the operation process. Different printing processes use different ink components, which may be incompatible. Therefore, in combination printing, it is necessary to test the ink compatibility before printing.

　　在對多種印刷工藝進行組合時，如果組合不妥，就會致使其間某一種印刷工藝的印刷速度影響到整體生產效率，所以應當對印刷工藝進行合理組合，保證所運用的組合式印刷機各機組之間的順序具有滿意的可變性，以滿意不同印品的組合印刷需求，并按印刷要求設置好各機組的印刷速度。

　　In the combination of various printing processes, if the combination is not appropriate, the printing speed of one printing process will affect the overall production efficiency. Therefore, a reasonable combination of printing processes should be carried out to ensure that the sequence of the combined printing press units used has satisfactory variability, in order to meet the combined printing needs of different printing products, and set up according to the printing requirements. Set up the printing speed of each unit.
