dossil

A dossil is a tightly rolled pad of linen or cotton cloth, typically 2 to 4 inches in diameter, used in copperplate and intaglio printing to wipe excess ink from the surface of the plate while preserving ink in the recessed lines and dots. The roller is held in the hand or palm and worked across the heated copper or steel surface in a controlled, directional motion, leaving a thin, even film of ink across the flatter areas while the engraved depressions retain their full deposit.

The cloth itself matters. Linters, starched cotton, and linen are traditional; modern printers sometimes use pre-rolled muslins or purpose-made wiper rolls. Softer cloth removes ink too aggressively; cloth that is too stiff or insufficiently rolled will skip or leave streaks. The dossil must be firm enough to glide without tearing and supple enough to follow the plate topography without gouging.

A printer typically works with multiple dossils in sequence during a single print run. The first pass, with a fresh roll, removes the bulk of surface ink; subsequent passes with slightly worn dossils refine the film and reduce residue. The timing is critical: a too-cool plate holds ink too thickly and fouls the dossil; an overheated plate may cause the cloth to smoke or stick. Many printers keep a dossil damp with turpentine or mineral spirits to prevent ink from caking on the cloth itself.

The term's origin remains obscure in printing literature, though "dossil" or "dossal" has been used in medical contexts for lint rolls since at least the seventeenth century.

Its appearance in printing vocabulary suggests it was simply adapted from surgical supply terminology. The practice of wiping intaglio plates by hand dates to the earliest etching and engraving workshops of the sixteenth century, but the term dossil became established only after the mechanization of other printing tasks made hand-wiping one of the few remaining manual finesse operations.

Intaglio printing cannot be fully mechanized at the wiping stage; even in industrial editions, the dossil remains the standard tool. In contemporary practices where photopolymer plates or digital intaglio techniques replace copperplate, wiping is often eliminated or automated, but traditional printmakers still regard dossil work as a hallmark skill, distinguishing hand-pulled proofs from production runs.
