Printing is actually a color reproduction process. In the process of reproduction, there will always be deviation. This deviation is called color difference! Due to the different varieties of each ink (such as environmental protection ink, UV ink, quick drying ink, etc.), manufacturers and raw materials, there are differences in the ink of different manufacturers. Therefore, when turning the sheet for printing, it is best to find the previous printing manufacturer for printing. Generally, the regular manufacturers will not easily replace the ink.

大家也许都听过印刷厂对于色差的解释，是说印刷品的标准是±10%是合格的，那么±10%的色差有多大呢，我们来做个比对就知道了，如果用三原色来做底色，色差是完全可以接受的。

You may have heard the explanation of the printing factory for the color difference, which means that the standard of Chinese printed matter is ± 10% qualified, so how big is the color difference of ± 10%. Let's make a comparison. If the three primary colors are used as the background color, the color difference is completely acceptable.

但是将两种三原色混合在一的话你会发现，深蓝色的色差大，只要红色油墨只要减少一点，颜色就偏冷，蓝色油墨减少一点，颜色就偏暖，这种是难的，因为每种油墨不论何种厂牌实际上均有不同的色偏现象，一般“青色（C）”均略带洋红而偏蓝，“洋红（M）”一般同时带青与黄而偏紫，只有“黄色（Y）”仅略带微量洋红而略微偏橙，所以要批量印出电脑显示屏上的深蓝色，是很难的。

However, if you mix the two three primary colors in one, you will find that the color difference of dark blue is the largest. As long as the red ink is reduced a little, the color will be cold, and the blue ink is reduced a little, the color will be warm. This is the most difficult to solve, because each ink, regardless of the brand, actually has different color deviation phenomena. Generally, "cyan (c)" is slightly magenta and blue, "magenta" (M) "Generally, it is purple with blue and yellow at the same time, and only" yellow (y) "is only slightly magenta and slightly orange, so it is difficult to print the dark blue on the computer display screen in batches.

有比深蓝色更难印的颜色吗？

Is there a color harder to print than dark blue?

当然有，那就是紫色。

Of course, that's purple.

印刷师傅看到底色是纯紫色的话，他想死的心都有，这不是开玩笑，无论是深紫色。

If the printer sees that the background color is pure purple, he wants to die. This is no joke, whether it is dark purple.

还是浅紫色。

Or light purple.

颜色偏差不是一点点，还有咖啡色。

The color deviation is not a little, but also coffee.

你以为这已经是偏色厉害的？

You think this is the worst color bias?

不，还有一个是公认不可能可以印出来的颜色，哪就是4色灰。

No, there is another color that is recognized as impossible to print, which is 4-color gray.

由于4色灰可以出现的颜色实在太多，济南印刷厂只显示几个明显的让大家感受一下。

Because there are too many colors that can appear in 4-color gray, t only shows a few obvious ones for everyone to feel.
