etching ink造句

• The matrix is inked and wiped as an intaglio using etching ink for the first color.
• Uncoated films require the use of an etching ink that penetrates the surface of the film.
• Etching ink is often fairly viscous, but has very low tack so the second color does not adhere to the textured areas.
• Because non-etching ink doesn't penetrate the surface of the film the way it penetrates paper, it is often possible to remove inked lines from drafting film when drawing on it by hand; an abrasive-free vinyl drafting eraser is the preferred tool for this, although a scalpel works too.
