打印机如何打印白色

The vast majority of the time we all print on white media: white paper, white cardstock, and other neutral white surfaces. But what about printing white? Can modern printers print white and if not, why not? Read on as we explore color theory, printer design choices, and why white is the foundation of the printing process.

在绝大多数情况下，我们都在白色介质上进行打印：白皮书，白色卡片纸和其他中性白色表面。但是打印白色呢？现代打印机可以打印白色，如果不能打印，为什么不打印？在我们探索色彩理论，打印机设计选择以及为什么白色是打印过程的基础时，请继续阅读。

问题 (The Question)

SuperUser reader Curious_Kid is well, curious, about printers. He writes:

超级用户阅读器Curious_Kid对打印机非常好奇。他写：

I was reading about different color models, when this question hit my mind.

当我想到这个问题时，我正在阅读有关不同颜色的型号的信息。

Can the CMYK color model generate white color?

CMYK颜色模型可以生成白色吗？

Printers use CMYK color mode. What will happen if I try to print a white colored image (rabbit) on a black paper with my printer? Will I get any image on the paper?

打印机使用CMYK彩色模式。如果我尝试用打印机在黑纸上打印白色图像(兔子)会怎样？我会在纸上得到任何图像吗？

Does the CMYK color model have room for white?

CMYK颜色模型是否有白色空间？

答案 (The Answer)

SuperUser contributor Darth Android offers some insight into the CMYK process:

超级用户贡献者Darth Android提供了有关CMYK流程的一些见解：

You will not get anything on the paper with a basic CMYK inkjet or laser printer. The CMYK color mixing is subtractive, meaning that it requires the base that is being colored to have all colors (i.e., White) So that it can create color variation through subtraction:

基本的CMYK喷墨或激光打印机不会在纸上留下任何东西。 CMYK颜色混合是减色的，这意味着它需要被着色的底材具有所有颜色(即White )，以便可以通过减法创建颜色变化：
White - Cyan - Yellow = Green
White - Yellow - Magenta = Red
White - Cyan - Magenta = Blue
White - Cyan - Yellow = Green
White - Yellow - Magenta = Red
White - Cyan - Magenta = Blue
White is represented as 0 cyan, 0 yellow, 0 magenta, and 0 black – effectively, 0 ink for a printer that simply has those four cartridges. This works great when you have white media, as “printing no ink” simply leaves the white exposed, but as you can imagine, this doesn’t work for non-white media.

白色表示为0青色，0黄色，0洋红色和0黑色–实际上，对于仅具有这四个墨盒的打印机，墨水为0。当您使用白色介质时，这种方法效果很好，因为“不打印墨水”只会使白色暴露在外，但是您可以想象，这不适用于非白色介质。

If you don’t have a base color to subtract from (i.e., Black), then it doesn’t matter what you subtract from it, you still have the color Black.

如果您没有要从中减去的基色(即Black )，那么从中减去什么也没关系，您仍然可以使用Black。

[But], as others are pointing out, there are special printers which can operate in the CMYW color space, or otherwise have a white ink or toner. These can be used to print light colors on top of dark or otherwise non-white media.

[但是]，正如其他人指出的那样，有一些特殊的打印机可以在CMYW色彩空间中运行，或者使用白色墨水或碳粉。这些可用于在深色或非白色介质上打印浅色。

You might also find my answer to a different question about color spaces helpful or informative.

您可能还会发现我对有关色彩空间的其他问题的回答很有帮助或有用。

Given that the majority of printer media in the world is white and printing pure white on non-white colors is a specialty process, it’s no surprise that home and (most) commercial printers alike have no provision for it.

鉴于世界上大多数打印机介质都是白色的，并且在非白色颜色上打印纯白色是一种特殊的过程，因此家用和(大多数)商用打印机都没有为此提供准备也就不足为奇了。
