Etched Portraits
The etching process reproduces artwork with fine detail as well as halftone photographs through acid-etching into metal sheet.
One method utilizes a halftone dot pattern, made from a 50-line screen. Halftone portraits resemble newspaper photographs with their visible dot patterns. The etched, recessed dots are black infilled to contrast with the satin-finished metal background.
The best photographs for halftone etched portraits have high contrast tones with bright white areas, dense black areas, and minimal grey tones. Photos that are monotone or have muted colors will produce poor halftone etchings. Halftone etchings are not available in aluminum.
The other type of etched metal portrait reproduces a black and white line drawing. Because a halftone screen is not used with hand-drawn art, the artist's fine lines are captured in great detail in the metal plate and can be etched deeper.
Etched portraits are recommended for interior use. However, deep-etched line art may be used outdoors.
