This innovative element established a continuous capillary connection between the nib and the inner walls of the barrel avoiding some of the particular problems that, in its time, had the use of fountain pens; difficulty starting the ink flow when starting to write; poor, excessive, or uneven ink flow; ink dripping from the pen when the ...
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 ...
A fountain pen is a writing instrument that uses a metal nib to apply water-based ink, or special pigment ink—suitable for fountain pens—to paper.It is distinguished from earlier dip pens by using an internal reservoir to hold ink, eliminating the need to repeatedly dip the pen in an inkwell during use.
A Flex nib (or flexible nib) is a type of fountain pen nib that can create different line widths. Due to its non-rigid structure, a flex nib allows a writer to control line width by adjusting the pressure of the pen on paper. Increased pressure will cause the two tines of the nib to separate slightly, allowing more ink to flow onto the page.
In 1928, under the direction of Kenneth Parker, the Parker Pen Company set out to develop a new and improved fountain pen ink. Inferior inks had long been the main cause of clogged fountain pens, yet popular ink formulations had remained unchanged in decades. Research for the project was initially outsourced to Miner Laboratories of Chicago.
The etching process causes micro surface scratches by removing styrene from the feed surface and ink channels. This roughening optimizes ink flow characteristics over the feed surface. [10] The 2000 fountain pen model uses nibs of another type which is incompatible with Lamy's other fountain pen models.

Additionally, "blobbing" ink on the drawing surface and "skipping" ink-flow require consideration when drawing with a ballpoint pen. [45] Although the mechanics of ballpoint pens remain relatively unchanged, ink composition has evolved to solve certain problems over the years, resulting in unpredictable sensitivity to light and some extent of ...
