Abstract
An inkjet printer is used to print on media an amplitude modulated (AM) halftoning pattern where dot size is varied to create different tones. Different sized dots are formed on the media by depositing different patterns of adjacent drops that coalesce into the different sized dots.
Claims15
A method for performing halftone printing, comprising:
- using an inkjet printer to print on media an amplitude modulated (AM) halftoning pattern where dot size is varied to create different tones, including,
- forming different sized dots on the media by depositing different patterns of adjacent drops that coalesce into the different sized dots.
An inkjet printer comprising:
- a plurality of nozzles that deposit ink drops on media;
- and,
- a controller that controls printing so that the inkjet printer prints on the media an amplitude modulated (AM) halftoning pattern where dot size is varied to create different tones and where different sized dots are formed on the media by depositing different patterns of adjacent drops that coalesce into the different sized dots.
An inkjet printer comprising:
- means for deposit ink drops on media;
- and,
- means for controlling deposition of the ink drops on the media so that the inkjet printer prints on the media an amplitude modulated (AM) halftoning pattern where dot size is varied to create different tones and where different sized dots are formed on the media by depositing different patterns of adjacent drops that coalesce into the different sized dots.
