In general, the more viscous the ink, the faster it will dry, but more writing pressure needs to be applied to dispense ink. But although they are less viscous, hybrid inks have a faster drying time compared to normal ballpoint inks. Also, a larger ball dispenses more ink and thus increases drying time.

The common ballpoint pen is a product of mass production, with components produced separately on assembly lines. [54] Basic steps in the manufacturing process include the production of ink formulas, molding of metal and plastic components, and assembly. [4] Marcel Bich (leading to Société Bic) was involved in developing the production of inexpensive ballpoint pens. [5] Standards [ edit ] In 1946, a Spanish firm, Vila Sivill Hermanos, began to make a ballpoint, Regia Continua, and from 1953 to 1957 their factory also made Bic ballpoints, on contract with the French firm Société Bic.
