I recently bought two fonts for a commercial project. I paid the creator a licensing fee to use his/her font on my product. I usually use free fonts for commercial projects, but I make sure I can use a font or quote etc. legally. Check out the following info.
Fonts, Copyright Laws, and Licensing
Technically, a “font” is a computer file or program that’s used to tell your printer how to print the shape of a letter of character or how it’s supposed to look on your computer screen. The actual shape of the letters and characters is called the “typeface.” For example, “Times New Roman” is a typeface, but the software that tells your printer how to print an “A” in Times New Roman is the font.
US copyright laws protect “original works of authorship,” such as writings, art work, and music. It also protects computer software. A copyright gives the owner the right to control the way his work is used by others. Generally, you need the owner’s permission to copy and use his copyrighted work. As a general rule, the copyright laws don’t cover typefaces, but fonts may be protected by copyright so long as the font qualifies as computer software or a program. Today, most fonts you come across are in fact programs or software.
Licensing is when an owner of copyrighted material lets someone use that material. When it comes to fonts and computer software, a license is usually called an End User License Agreement. Usually, you’re charged a fee for the license, and the agreement limits how you may use the software. For example, an agreement typically lets you use the software on one computer only.
