spitbite
n.— «There were lines so skilfully crisscrossed by the artist and so perfectly printed that they looked 3-D, like actual black threads. I learned a new word, spitbite, a process of mixing ink with soap (originally spit, I gather).» —“Stirrings for a congregation of like-minded artists” by Nancy Bauer Telegraph-Journal (Saint John, New Brunswick, Canada) Mar. 28, 2009.
