Clairefontaine and Rhodia papers are often cherished by fountain pen users because their water based inks typically do not bleed through or feather on our papers. How does this work? Clairefontaine manufactures the papers in a such a way that it resists more ink rather than it absorbs. (Want to learn more about paper manufacturing processes? Check out Clairefontaine’s Paper Vocabulary here.)
Downsides to this process? For some, depending on the size of the nib, type of ink used, and or relative humidity, ink might take longer to dry on the page. (This is why blotting paper was invented. J. Herbin makes blotting paper)
Is the length of time it takes for ink to dry on the page important to you? Have you ever switched to a different paper because of it? Do you use blotter paper?
