Use fonts safely in business. Copyright statement:
1. Pay attention to the free authorized object of fonts.
For example, many fonts on the Internet are only licensed to individual users for free, but most commercial use requires payment. For such fonts, you must check the license agreement before using them.
2. Pay attention to the free authorization statement.
Although some fonts are licensed for commercial use free of charge, they still need to be authorized by the copyright owner when used for commercial purposes. For example, the imitation of Song by Founder in Founder Font Library is definitely free in Founder Font Library official website, but users must obtain the written authorization from Founder Company when operating (just don't need to pay the authorization fee), otherwise they still face the risk of infringement.
