印刷机扫描仪原理
An understanding of the principles of a printing machine scanner
requires a grasp of both printing and scanning technologies.
理解印刷机扫描仪的原理需要对印刷和扫描技术有所了解。
Firstly, let's delve into the printing technology aspect of the scanner.
Printing machines work by transferring ink onto paper to create
images and text. In traditional printing, this is achieved through a
process of applying ink to a printing plate, which is then transferred
to a rubber blanket before being applied to the printing surface.
首先，让我们深入了解扫描仪的印刷技术方面。印刷机通过将墨水转移到纸
张上来创建图像和文字。在传统印刷中，通过将墨水涂在印刷版上，然后转
移到橡皮毯上再应用到印刷表面来实现这一过程。
The scanner component of the printing machine is responsible for
converting the physical printed image into digital data that can be
stored and manipulated electronically. This involves the use of
sensors or charged coupled devices (CCDs) to capture an image of
the printed material and convert it into a series of digital signals.
印刷机的扫描仪组件负责将印刷的物理图像转换为可以电子存储和操控的数
字数据。这涉及使用传感器或电荷耦合器件（CCD）来捕捉印刷材料的图像
并将其转换为一系列数字信号。
In terms of scanning technology, there are several key principles at
play. One fundamental principle is the use of light and sensors to
capture the image. When the printed material is placed on the
scanner, a light source illuminates the document and the reflected
light is detected by the sensors, thus creating an electronic
reproduction of the printed image.
在扫描技术方面，有几个关键原则起作用。一个基本原则是使用光和传感器
来捕捉图像。当印刷材料放在扫描仪上时，光源照亮文件，传感器检测到反
射光，从而创建印刷图像的电子复制。
Another important principle is the concept of resolution, which refers
to the level of detail that can be captured by the scanner. Higher
resolution scanners are capable of capturing finer details, resulting in
a higher quality digital reproduction of the printed material.
另一个重要原则是分辨率的概念，它指的是扫描仪可以捕捉的细节水平。分
辨率更高的扫描仪能够捕捉更精细的细节，从而产生印刷材料更高质量的数
字复制品。
Additionally, the scanning process involves the conversion of the
analog image into a digital format. This is achieved through a
process called sampling, where the image is divided into a grid of
pixels and the brightness of each pixel is measured and converted
into a digital value.
此外，扫描过程涉及将模拟图像转换为数字格式。这是通过一个称为采样的
过程实现的，其中图像被分成一个像素网格，并测量每个像素的亮度并转换
为数字值。
It is important to note that the principles of a printing machine
scanner are constantly evolving with advancements in technology. As
such, the ability to understand and adapt to these changes is crucial
for those working in the printing and scanning industries.
值得注意的是，随着技术的进步，印刷机扫描仪的原理不断发展。因此，理
解和适应这些变化对从事印刷和扫描行业的人来说至关重要。
