Half-tone

There are two different types of half-tone:
Amplitude modulated rastering (AM): Resolution in a constant number of dots per area, the dot sizes are variable.
Frequency modulated rastering (FM): The dots are as small as possible but the size is constant. The number of dots per area is variable.

Half-tone printing

Printing of in halftone dots converted continuous-tone images, consisting of individual raster dots.

Hydrophilic
