1. Conversion of colours

客户有时分给我们的是RGB文件，我们要经过什么手腕才干转换成CMYK的呢?假如每家印刷企业所运用的转换规范不一样，那么转换后的CMYK文件颜色也会不一样的。其次，就算是同样的文件，经过数码印刷、胶印、凹印等不同的印刷方式，台历、挂历印刷出来的颜色也会存在一些差异。

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、档案转换

2. Archives Conversion

网点总量不一样也可能会影响终的颜色效果，另外，加网技术的不同使得不同的网型其网点扩展率也各不同。举个例子，假如今天CTP设备出了问题，换别的CTP去出版，终的印刷颜色可能会有一定量的区别。

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、出版过程

3. Publishing process

由于板材厂商的技术、加网网型以及网点扩展定义可能有所不同，版材网点的曝光率不同以及冲版设备都会影响印版的质量。假如出版过程没有一个统一的规范，很难做到每批台历印刷、挂历印刷一样。

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、设备不同

4. Different equipment

每家印刷厂的印刷设备的网点扩展率都是不一样的。也就是说，即使是给了你同一套版，同样的承印物和耗材，在不同的印刷机上也不一定可以得到类似的印品。所以相关的操作人员懂得网点扩展率这个概念就显得十分的重要。CTP不只能够做各种数据的采集，还能够停止网点补偿。

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、纸张质量

5. Paper Quality

在采购的时分对每个批次的纸张做质量检验，同时将这些检验数据交给纸商，这样能有催促的力气将纸张的质量越做越好。

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、油墨质量

6. Ink Quality

油墨的不同关于台历印刷、挂历印刷的质量影响十分大。油墨的活动性不同，油墨的色相也不同。印企在每批次的采购时也要有相应的丈量和统计，以保证不同批次质量的稳定性。

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.
