How you like to define it is partly science, partly philosophy. Ink Drying Time: is the time needed to evaporate at least the water, maybe all of the volatile components of a drawn ink line on paper with nothing else than the inks solids (and maybe non-water liquids) remaining.

First results will be introduced in this forum entry and the conclusion will be called shortly: Ink Set Time.

Thoughts about how to tackle the difference between being set and being dried could not be answered without new measurements. The ink can still be „wet“ but is sucked into the spaces between cellulose fibres and is not smearable any longer. Sounds right? It is not! While commonly used in casual communication, a perceivably dry ink line does not need to have all of its volatile components evaporated and removed from the paper. The time between drawing the line and the first time the line behaves as if it has fully dried is called drying time. Ink Set Time on the paper: is what we visually observe, either by naked eye or with a loupe or by doing a smear test or similar.

To my understanding, flow is a kinetic property of ink and things like viscosity do have little effect on how much ink is put on the paper while drawing a line with a fountain pen.) (Remark: „ink flow“ is often used in casual communication. The term Ink Wetness, while commonly used in casual communication, is an unjustified simplification, has more than one meaning and should always be replaced by ink delivery to the paper, or short: Ink Delivery. While there is no error in the facts or in the measurements nor in the conclusions, the term ink wetness was used as a synonym to ink delivery amount. Ink Delivery to the paper: This part was deeply investigated during previous measurements, reported in this thread ( see here) and finally resulted in a scientific journal paper ( see here). To bring structure to this topic, I like to split the process of line drawing with a fountain pen into three stages and introduce three terms that should make it ascertainable: However, that is not what is really going on! Nothing wrong here, we all observe it in similar ways and we understand what is meant when we describe our observations. Comparing different inks, we see more or less ink delivery (more wet or more dry ink lines) and longer or shorter drying times. While we draw lines we observe ink flowing out of the fountain pen, building lines on the paper that stay visibly wet for a certain time and dry afterwards.

However, that‘s not what is really going on the sun does not move through the sky!īack to fountain pen ink on paper. We all can observe it that way and will understand what is meant. I like to start this entry with an another common daily life topic that compares quite well with the ink situation: For describing the position of the sun during the day most, if not all, people will use something equivalent to „the sun is moving through the sky during the day“. Are you ready for a deep dive into facts and conclusions about the relation between fountain pen ink properties, how we describe our observations about the visual appearance of ink on paper and about what is really going on?
