1. Conversion of colours

客戶有時分給我們的是RGB文件，我們要經(jīng)過什么手腕才干轉換成CMYK的呢?假如每家印刷企業(yè)所運用的轉換規(guī)范不一樣，那么轉換后的CMYK文件顏色也會不一樣的。其次，就算是同樣的文件，經(jīng)過數(shù)碼印刷、膠印、凹印等不同的印刷方式，臺歷、掛歷印刷出來的顏色也會存在一些差異。

Customers sometimes give us RGB files. What skills do we need to convert them into CMYK? If every printing enterprise uses different conversion specifications, the color of the converted CMYK files will be different. Secondly, even if it is the same document, through digital printing, offset printing, gravure printing and other different printing methods, calendar, calendar printing out of the color will also have some differences.

2、檔案轉換

2. Archives Conversion

網(wǎng)點總量不一樣也可能會影響終的顏色效果，另外，加網(wǎng)技術的不同使得不同的網(wǎng)型其網(wǎng)點擴展率也各不同。舉個例子，假如今天CTP設備出了問題，換別的CTP去出版，終的印刷顏色可能會有一定量的區(qū)別。

Different total number of dots may also affect the final color effect. In addition, the different screening technology makes the dot expansion rate different for different meshes. For example, if today's CTP equipment is out of order and another CTP is to be published, the final printing color may have a certain difference.

3、出版過程

3. Publishing process

由于板材廠商的技術、加網(wǎng)網(wǎng)型以及網(wǎng)點擴展定義可能有所不同，版材網(wǎng)點的曝光率不同以及沖版設備都會影響印版的質量。假如出版過程沒有一個統(tǒng)一的規(guī)范，很難做到每批臺歷印刷、掛歷印刷一樣。

Because the technology, screen type and dot extension definition of plate manufacturers may be different, the exposure rate of plate dots and the printing equipment will affect the quality of plate. If the publishing process does not have a unified standard, it is difficult to do the same for each batch of calendar printing and calendar printing.

4、設備不同

4. Different equipment

每家印刷廠的印刷設備的網(wǎng)點擴展率都是不一樣的。也就是說，即使是給了你同一套版，同樣的承印物和耗材，在不同的印刷機上也不一定可以得到類似的印品。所以相關的操作人員懂得網(wǎng)點擴展率這個概念就顯得十分的重要。CTP不只能夠做各種數(shù)據(jù)的采集，還能夠停止網(wǎng)點補償。

The dot expansion rate of printing equipment in each printing plant is different. That is to say, even if you are given a set of copies, similar prints and consumables may not be available on different printing presses. Therefore, it is very important for operators to understand the concept of dot expansion rate. CTP can not only collect all kinds of data, but also stop network compensation.

5、紙張質量

5. Paper Quality

在采購的時分對每個批次的紙張做質量檢驗，同時將這些檢驗數(shù)據(jù)交給紙商，這樣能有催促的力氣將紙張的質量越做越好。

At the time of purchasing, the quality of each batch of paper is checked, and the inspection data are handed to the paper merchant, so that the quality of paper can be better and better.

6、油墨質量

6. Ink Quality

油墨的不同關于臺歷印刷、掛歷印刷的質量影響十分大。油墨的活動性不同，油墨的色相也不同。印企在每批次的采購時也要有相應的丈量和統(tǒng)計，以保證不同批次質量的穩(wěn)定性。

Different ink has great influence on the quality of calendar printing and calendar printing. Ink has different activity and color. Printing enterprises should also have corresponding measurement and statistics in each batch of purchasing to ensure the stability of the quality of different batches.
