软件选择
Software selection
Photoshop是用来处理图片的，不到万不得已别用来排版，特别是有文字内容的（请大家不要笑，这种情况很多）；请用AI、Indesign等，原因是PS排出来的文件，文字终都会变成图片格式，容易发虚。
Photoshop is used to process pictures. As a last resort, don't use it for typesetting, especially those with text content (please don't laugh, there are many such cases); Please use AI, InDesign, etc. the reason is that the text of the PS file will eventually become a picture format, which is easy to be false.
颜色模式
Color mode
用CMYK，不要用RGB。原因是：后期材质的颜色表达模式和表达范围，与你在电脑上看到的是不一样的。
Use CMYK instead of RGB. The reason is that the color expression mode and expression range of later materials are different from what you see on the computer.
一般来说，普通纸张印刷的色彩范围，要远小于设计师电脑显示的颜色范围（特别是苹果电脑），这也是为什么每个设计师都认为，设计作品印出来，总是没有你设计的好看。
Generally speaking, the color range of ordinary paper printing is much smaller than the color range displayed by the designer's computer (especially Apple Computer), which is why every designer believes that the printed design works are always not as good-looking as your design.
图像精度
Image accuracy
如果是用于印刷，请确保图像都在300dpi以上（不缩放原始图片尺寸的前提下），不够的话，会有发虚的可能。
If it is used for printing, please ensure that the images are above 300dpi (without scaling the original image size). If it is not enough, it may be false.
叠印问题
Overprint problem
对于图形/转曲后的文字/LOGO等来说，注意叠印，可通过视图-叠印预览来查看是否有异常。常常一些LOGO和文字做了叠印但是不知道，结果印刷如果也未检查出来并提醒就印不出来了，这有时会导致重大错误发生。
For graphics / text after turning / logo, pay attention to overprint. You can check whether there are exceptions through view overprint preview. Often some logos and characters are overprinted, but I don't know. If the printing result is not checked and reminded, it can't be printed, which sometimes leads to major errors.

文字方面
Literal aspect
字体的应用：不是你用的每个字体，后期印厂都有；也不是你用的每个字体，都是可以印刷的（字体分显示字体和印刷字体）；所以在给印厂文件时，如果确定不会有文字的修改，可以将文字（包括复合字体）全部转曲，这样能避免各种字体的问题。
Font application: not every font you use, but in later printing plants; Not every font you use can be printed (font can be divided into display font and printing font); Therefore, if you are sure that there will be no text modification when sending documents to the printing plant, you can turn all the text (including composite fonts), so as to avoid the problems of various fonts.
文字的颜色：如果没有特别的要求，黑色字请用单色黑，原因是除非很大的字，如果是四色，由于机器的误差，存在套印的问题，很容易文字发虚，不好看。
Text color: if there are no special requirements, please use monochrome black for black words. The reason is that unless it is a large word, if it is a four-color word, there is a problem of overprint due to the error of the machine, it is easy to make the text false and ugly.
文字的大小：如果是反白字，由于底色你很难保证是单色，所以依然存在套准的问题，所以反白字的字体，尽可能不要太小。
Text size: if it is anti white, it is difficult to guarantee that the background color is monochrome, so there is still a problem of registration, so the font of anti white should not be too small as far as possible.
