When water climbs up paper, it demonstrates capillary action, which is the ability of a liquid to flow in narrow spaces without the assistance of external forces like gravity. This happens because of the cohesive and adhesive forces between the water molecules and the paper fibers, allowing the water to move against gravity through the tiny spaces in the paper.
Fountain pens use capillary action in addition to gravity to draw ink from the reservoir onto the nib and onto the paper. The capillary action helps control the flow of ink onto the paper, resulting in a smooth and consistent writing experience.
Pens operate on the scientific principles of gravity, capillary action, and fluid dynamics. Gravity helps the ink flow from the pen to the paper, capillary action ensures the ink is drawn towards the paper through a narrow tube or point, and fluid dynamics govern how the ink spreads and dries on the paper.
No, ballpoint pens work based on capillary action. The ink is drawn from the reservoir onto the ball at the tip through capillary action, which allows for controlled and consistent ink flow onto the paper.
When ink from a pen touches paper, it is absorbed into the paper fibers due to capillary action. The ink then dries on the paper surface, leaving a permanent mark.
Capillary action is used in various ways in daily life, such as in the function of plant roots absorbing water from soil, the spreading of ink on paper, and the movement of blood through tiny blood vessels in our bodies. It also plays a role in the absorption of water and nutrients by paper towels and sponges.
A paper towel absorbing liquid is an example of capillary action.

There isn't really a "rule" persay, but Capillary Action has a lot to do with it.
For one, fountain pens rely on capillary action to draw the ink towards the nib and onto the paper. Capillary action is a phenomenon that is easily applicable to science because it demonstrates surface tension of liquids in action.
Blotting paper is highly absorbent due to its porous structure, which allows it to draw in and hold liquids such as ink. As ink comes in contact with the blotting paper, its capillary action pulls the ink into its fibers, resulting in the ink being absorbed and transferred away from the surface it was on.

Capillary action is also essential for the drainage of constantly produced tear fluid from the eye. Paper towels absorb liquid through capillary action. Chemists utilize capillary action in thin layer chromatography, in which a solvent moves vertically up a plate via capillary action. Dissolved solutes travel with the solvent at various speeds depending on their polarity. With some pairs of materials, such as mercury and glass, the interatomic forces within the liquid exceed those between the solid and the liquid, so a convex meniscus forms and capillary action works in reverse.
It has to do with the difference in affinity between the dyes that make up the ink or food coloring and the blotting paper compared to the solvent. This is paper chromatography. The dyes are carried along by the solvent (water) but is attracted to the substrate (the blotting paper). Some inks travel faster than others.
