These are printed forms of regular script. They're the most widely-used general styles of Chinese Hanzi, Japanese Kanji, and Korean Hanja.
Kaishuprint 1-5 are typical of the styles used to teach school children to write in Asia.
Most Chinese, Japanese, and Korean people will tell you that in printed form, these look very basic, and do not contain the true art of the characters/calligraphy.
However, most tattoos in the west seem to use this kind of printed style. Using a this is the equivalent of getting a tattoo in "Arial" font in English.
Romanized as Kaishu from Chinese and Kaisho from Japanese.
I recently added Kaishuprint 5-11. I recommend Kaishuprint7 and Kaishuprint8 if you like this general printed style.
