uni-ball products are developed through technical expertise accumulated over the years include “uni-ball” water based ink balls with metal tips that dominate the world market.
An established product with reliable features.
The “UNI-FLOW SYSTEM” ensures a continuous write with the same thickness to the very last drop of ink.
Dyestuff Ink particle is easily soluble in water and will bleed on the paper, uni super ink – pigmented ink will bond itself to the paper fibers once it is settled, it is not soluble in water.
The size of uni super ink particle is larger than dyestuff Ink. Therefore its surface is less affected and the colour remains vivid.
Difference between structure of molecules. Molecules of dye ink break down because of the sunlight and air but uni Super ink is difficult to break down.
Gel Ink and Twin-Ball Structure of the Twin-Ball Mechanism:
Employing a water-based gel ink, Signo ensures constant ink flow without blurring or dripping. Its twin-ball mechanism prevents excessive ink flow.
When the pen is positioned in a downward position, the ink flows smoothly from the ink flow channel.
When the pen is positioned in an upward position, the reverse flow prevention ball works to stop the flow of air into the ink.
Gel ink writes smoothly and does not blur!:
When you start writing, the ball in the pen rotates to mix the viscous ink causing it to thin.
The pen glides on paper, providing a smooth write.
Once the ink touches the paper, it hardens quickly when returning to its previous viscosity, which allows you to draw lines that do not blur.
