3. Other information
1. The pdf template is made using Adobe Acrobat DC, the software download address: link: https://pan.baidu.com/s/1WnQBxwC9EzL2iFX5RJY_cQ Extraction code: apbw, contains cracking software, tutorial piece Baidu
2. Template production requirements: To set the form text field, you need to set the relevant attributes of the text field, such as the position, range size, font size, whether the font is displayed in a new line, the name of the field, and other important content;
3. The Chinese uses the Song Ti font;
Note: Due to the high level of physical examination for the elements of the template during the use of the dpf template, it is recommended to choose carefully.
