First, start with the document production before printing. 1. When creating a new document, whether it is making an album, leaflet or packaging, we need to select the color mode of the document as CMYK and set a 3mm bleeding.

二、印刷里说的A4纸，是210X285mm,A5纸的尺寸是210X140mm,A3纸的尺寸是420X285mm，不要选软件默认的规格。那个是打印尺寸，不是印刷尺寸，请谨记！

2、 A4 paper mentioned in the printing is 210x285mm, A5 paper is 210x140mm, and A3 paper is 420x285mm. Do not choose the default specification of the software. That's print size, not print size, please remember!

三、在做好成品尺寸（包装是展开的刀版图）后，马上制作角线。

3、 After making the finished product size (the package is the unfolded knife layout), make the corner line immediately.

角线是两条6mm的线，垂直与水平各一条中的设置是这样：

The corner line is two 6mm lines, one vertical and one horizontal. The setting is as follows:

在CDR中是这样这样设置：

In CDR, it is set as follows:

四、设置好出血、角线后，就要设置版心了，版心的大小没有规定，但是四边一定要离裁切位3mm以上。包装的话，我一般都会设置为5mm。

4、 After setting the bleeding and corner lines, set the layout center. The size of the layout center is not specified, but the four sides must be more than 3mm away from the cutting position. For packaging, I usually set it to 5mm.

做完这些基本设置，就可以开始设计包装、单张、画册等印刷品的内容了

After completing these basic settings, you can start designing the contents of printed materials such as packaging, leaflets and picture albums
