first of all, you should understand what R is: R is the abbreviation of REGISTER, and when used in trademarks, it means registered trademarks. The circle R is the mark of "registered trademark", which means that the trademark has been registered in the State Trademark Office and has been examined and approved by the Trademark Office, and has become a registered trademark. R trademark has the characteristics of exclusiveness, exclusiveness and uniqueness [1], which belongs to the owner of the registered trademark and is protected by law. No enterprise or individual may use it without the permission or authorization of the owner of the registered trademark, otherwise it will bear tort liability. Then the problem comes. For example, if you print "Yili" products, these products all have an R after their trademarks. If this manufacturer has passed the trademark registration, and you verify that the unit looking for your printing is a regular manufacturer of "Yili" and has the printing authorization of this manufacturer, it is not illegal. If you print privately, for example, for illegal traders who make and sell fakes, this is illegal.
