gravyrfärger

Gravyrfärger, also known as engraving inks, are specialized inks designed for use in the intaglio printing process, particularly engraving and etching. These inks are typically characterized by their high viscosity and their ability to hold fine detail. Unlike inks used in relief printing, gravyrfärger are not designed to be wiped away completely from the non-engraved surface of the plate. Instead, excess ink is carefully wiped from the plate's surface, leaving the ink within the incised lines or recessed areas.

The formulation of gravyrfärger often includes a strong binder, such as linseed oil or alkyd resin, which provides durability and adhesion. Pigments are chosen for their lightfastness and intensity, ensuring that the printed image remains vibrant over time. The viscosity is crucial for the ink to remain in the etched grooves and not smudge during the wiping process. This high viscosity also contributes to the characteristic "bite" or texture often associated with intaglio prints.

Gravyrfärger are used in various printmaking techniques, including drypoint, etching, aquatint, mezzotint, and traditional engraving. The choice of ink can significantly influence the final appearance of the print, affecting the richness of the blacks, the subtlety of the tones, and the overall clarity of the image. Artists and printmakers select specific gravyrfärger based on the desired effect, the type of plate material, and the printing press capabilities. The drying time of these inks is often slower than that of other ink types, allowing for the careful manipulation required in the intaglio process.
