Plate printing is more common in the market. Printing houses will focus on printing and printing of common printed matter, but less printing is suitable for printing, so as to save printing costs. The problems of different combined printing process need to be paid attention to in printing factory.

合版印刷就是將不同的畫(huà)冊(cè)相同紙張、相同克重、相同色數(shù)、相同印量的印件組合成一個(gè)大版，充分利用膠印機(jī)有效印刷面積，形成批量和規(guī)模印刷的優(yōu)勢(shì)，共同分?jǐn)傆∷⒊杀?，達(dá)到節(jié)約制版及印刷費(fèi)用的目的。

Co printing is to combine different albums with the same paper, the same gram weight, the same color number and the same printing quantity into a large plate, make full use of the effective printing area of offset press, form the advantages of batch and scale printing, share the printing cost together, and achieve the purpose of saving plate making and printing costs.

合版印刷相對(duì)于專(zhuān)版印刷，合版印刷的優(yōu)勢(shì)使單價(jià)比較低，少量可制作，交貨速度快。但鑒于合版印刷采用網(wǎng)絡(luò)傳版，集中印刷，分?jǐn)傎M(fèi)用的方式，也存在缺失，在合版印刷中難免會(huì)造成色差的問(wèn)題。因合版印刷為多個(gè)客戶(hù)檔案拼版印刷，因此無(wú)法考量單一客戶(hù)對(duì)顏色要求及調(diào)正，如拼在重墨區(qū)時(shí)，顏色即會(huì)偏重，一般來(lái)說(shuō)合版印刷會(huì)有約略10%的印刷色差，就算是同一印刷檔同一印刷紙質(zhì)，每批多少也會(huì)存在著色差。

Compared with special printing, combined printing has the advantages of low unit price, small amount of production and fast delivery. However, in view of the lack of network transmission, centralized printing and cost sharing, color difference is inevitable in CO printing. Due to the combination printing of multiple customer files, it is impossible to consider the color requirements and adjustment of a single customer. For example, when it is combined in the heavy ink area, the color will be biased. Generally speaking, there will be about 10% printing color difference in combination printing. Even if it is the same printing file and the same printing paper, there will be color difference in each batch.

滿(mǎn)版色塊（大范圍只有單一色塊無(wú)論深淺）在印刷時(shí)容易造成重影及滾輪痕跡或印墨不均問(wèn)題，若是對(duì)顏色要求的客戶(hù)，建議以專(zhuān)版印刷為優(yōu)。所以在印刷上需要格外注意，統(tǒng)一色彩管理流程，將不同的客戶(hù)的畫(huà)冊(cè)印刷文件整合進(jìn)行調(diào)圖，再進(jìn)行拼版印刷；相同色調(diào)的印刷文件進(jìn)行排列。

Full color block (large range of only a single color block, regardless of the depth) is easy to cause double image and roller marks or uneven printing ink when printing. For customers who require color, special printing is recommended. Therefore, we need to pay special attention to the printing, unify the color management process, integrate the printing files of different customers' albums, adjust the drawings, and then make up printing; The printed documents of the same tone are arranged.

對(duì)于正規(guī)合版需要根據(jù)印刷的需要以及印刷廠(chǎng)印刷設(shè)備的不同，在上機(jī)印刷前拼版的時(shí)候要按照實(shí)際情況進(jìn)行不同的調(diào)整，在對(duì)開(kāi)和全開(kāi)的印刷機(jī)上可以用套曬、拼曬，并通過(guò)自翻身或正反印刷。在進(jìn)行拼版的時(shí)候個(gè)注意拼接部分需要留出6毫米的出血位，即每個(gè)單頁(yè)四周需要留出3毫米的出血。

For the normal combination, different adjustments should be made according to the needs of printing and the different printing equipment of the printing plant before printing. In the split and full open printing press, it can be used to cover the sun, spell the sun, and through self turning or positive and negative printing. In the process of making up, we should pay attention to the 6 mm bleeding space in the splicing part, that is, 3 mm bleeding space around each single page.

合版印刷為印刷行業(yè)打開(kāi)了另一個(gè)市場(chǎng)，在一定程度上既滿(mǎn)足了不同客戶(hù)小印量的印刷產(chǎn)品質(zhì)量，又滿(mǎn)足客戶(hù)有限的經(jīng)費(fèi)上的問(wèn)題。但是它存在的缺陷也是需要企業(yè)特別關(guān)注的，希望企業(yè)能夠根據(jù)自己的需求確認(rèn)印刷方式。

Co printing has opened another market for the printing industry. To a certain extent, it not only meets the printing product quality of different customers with small printing volume, but also meets the problem of customers' limited funds. But its defects also need special attention of enterprises, hoping that enterprises can confirm the printing method according to their own needs.
