halftone engraving
Học thuậtThân thiện
Definition
Noun: A printing technique used to reproduce photographs or illustrations with continuous tones (like shades of gray) by converting the image into a pattern of small dots of varying sizes. The dots are spaced equally, but their size varies to create the illusion of different shades. This technique is also known as a "halftone" in the printing industry.
Usage
This term specifically refers to the engraved plate or the resulting printed image itself that uses the halftone process. It is a technical term used in printing, graphic arts, and historical discussions of illustration reproduction.
Examples
- The magazine cover from 1920 was a beautiful example of a halftone engraving.
- Before digital printing, newspapers relied on halftone engravings to print photographs.
- The artist studied the halftone engraving to understand the dot pattern.
Advanced Usage
