If the ball socket were too tight or the ink too thick, it would not reach the paper. If the socket were too loose or the ink too thin, the pen would leak, or the ink would smear. [5] Ink reservoirs pressurized by a piston, spring, capillary action, and gravity would all serve as solutions to ink-delivery and flow problems. [12] [13]

Close up of an extra fine roller ball pen next to something written with it.

The pen is available in many different ink colors, ranging from the classic blue, black, red, and green of traditional offices, to pink, purple, and other modern and artistic colors. The thick ink flows down due to capillary action from the tube inside the barrel, to feed the ball, which can rotate within a brass bearing. [ 13 ]

When I got them, they became my favorite pens because of the fine point, the ink flow, the comfort in the hand. Wow. You pull the cap off and it will snap on to the other end. I keep ordering more.
The ideal fountain pen ink is free-flowing, free of sediment, and non-corrosive. These qualities may be compromised in the interests of permanence, manufacturability and in order to use some widely available dyes. [4] A form of ink that predates fountain pens by centuries is iron gall ink. This blue-black ink is made from iron salts and tannic ...
Ink is held within all four legs, with casters designed to disperse the ink as the chair is rolled. Malouin experimented with various combinations of ball points and ink viscosities before arriving at a design which would support the weight of a person while allowing ink to flow in the same manner as a ballpoint pen.
