Ink Transit (Gravure)

Not too dry

Dry ink within the print cylinder presents another foe to effective ink transfer. Frank Passarelli, product business manager at Bobst Schiavi, shares his company's method for keeping ink fresh: "Encapsulate the printing group area to allow for an atmospheric condition that increases the solvent concentration within the encapsulated area." This technique avoids dry ink by keeping the cylinder humid after the printing nip. Passarelli maintains in doing so, press operators will avoid solvent evaporation from the residual ink inside the engraved cells.
