  • Patent number: 11973919
    Abstract: A printing system is disclosed. The printing system includes at least one physical memory device to store ink model estimation logic and one or more processors coupled with the at least one physical memory device to execute the ink model estimation logic to receive a first plurality of ink deposition curves each associated with one of a plurality of primary color inks of a print system, wherein the associated primary color inks in combination represent a first secondary color, receive a color space mapping profile for the print system, wherein the color space mapping profile characterizes a relationship between a first color space and a printer color space of the print system and generate a color space ink model for the first secondary color based on the first plurality of ink deposition curves and the color space mapping profile, wherein the color space ink model represents a relationship between each of a plurality of parameters of the first color space and ink deposition.

  • Publication number: 20190048200
    Abstract: A method of making carbon black. A method of making carbon black is described including combusting feedstock with plasma in an apparatus having a series of unit operations with individual capacities. The individual capacities of the unit operations are substantially balanced by replacing at least part of the feedstock with a feedstock having a molecular weight heavier than methane. This results, among other things, in increased utilization of the individual capacities of the unit operations and increased overall throughput.
