Abstract
A printer includes an ink reservoir that includes yellow ink, cyan ink, and magenta ink. The printer includes an ink dispenser that employs a yellow distribution setting to increase the drop volume of yellow ink droplets and lower the drop frequency of the yellow ink droplets on the media with respect to the cyan ink droplets and/or magenta ink droplets to control the lightfastness of the print on the media.
Claims15
A printer, comprising:
- an ink reservoir that includes yellow ink, cyan ink, and magenta ink;
- and
- an ink dispenser that employs a yellow distribution setting to increase the drop volume of yellow ink droplets and lower the drop frequency of the yellow ink droplets on the media with respect to the cyan ink droplets and/or magenta ink droplets to control the lightfastness of the print on the media.
A method comprising:
- setting a cyan distribution setting for a given drop volume and drop frequency of cyan ink droplets on a media in a printer;
- setting a magenta distribution setting for a given drop volume and drop frequency of magenta ink droplets on the media in the printer;
- and
- setting a yellow distribution setting for an increased drop volume and reduced drop frequency of yellow ink droplets with respect to the drop volume and drop frequency of cyan ink droplets and/or magenta ink droplets to control lightfastness of a print on the media.
1 more element
An apparatus comprising:
- a cartridge installable in a printer, wherein the cartridge includes yellow ink, cyan ink, and magenta ink for the printer;
- and
- an ink dispenser in the cartridge that employs a yellow distribution setting to increase the drop volume of yellow ink droplets and lower the drop frequency of the yellow ink droplets on the media with respect to the cyan ink droplets and/or magenta ink droplets to control the lightfastness of the print on the media.
