Color management system for application of color to substrates
Methods, systems and computer readable media for color management are described. In some implementations, the method can include accessing one or more buildup curves associated with a combination of a substrate, one or more colorants and a colorant dispenser. The method can also include accessing a design file specifying a design and including one or more layer files each specifying a layer color. The method can further include generating, for each layer color, a corresponding colorization recipe based on the one or more buildup curves. The method can also include creating a production job instruction/metadata file having a link to the design instruction/metadata file and including parameters associated with the colorant dispensing job to be carried out using the design instruction/metadata file.

3 . The method of claim 2 , wherein the chemical is the colorant.
4 . The method of claim 2 , wherein the amount of the chemical is determined based on a colorant recipe of the one or more colorant recipes determined responsive to a spectral measurement from the spectrophotometer.
5 . The method of claim 2 , wherein the substrate is non-moving with respect to the dispenser.
6 . The method of claim 2 , wherein the substrate is moving with respect to the dispenser.
7 . The method of claim 2 , wherein the location is specified in terms of pixel values in the one or more layer files.
8 . A system comprising one or more processors configured to perform operations comprising:
transmitting colorant dispensing data to a colorant dispenser, the colorant dispensing data including:
one or more layer files each specifying a color of one or more pixels, and
one or more colorant recipes, each colorant recipe corresponding to a layer file, wherein the colorant recipe is generated based on one or more buildup curves associated with a combination that includes each of a substrate, one or more colorants and the colorant dispenser, the one or more buildup curves specifying optical characteristics of prints generated using the combination, each layer file and corresponding colorant recipe configured to be effective to cause the colorant dispenser to dispense a respective colorant of the one or more colorants onto the substrate at a location specified by each of the one or more pixels of each corresponding layer file.
9 . The system of claim 8 , wherein the colorant dispenser comprises:
a spectrophotometer coupled to the one or more processors; and
wherein the one or more processors are configured to dispense an amount of a chemical at a specified location of the substrate via the colorant dispenser and based on at least one of the one or more colorant recipes generated based on the one or more buildup curves.
10 . The system of claim 9 , wherein the chemical is the colorant.
11 . The system of claim 9 , wherein the amount of the chemical is determined based on a colorant recipe of the one or more colorant recipes determined responsive to a spectral measurement from the spectrophotometer.
12 . The system of claim 9 , wherein the substrate is non-moving with respect to the dispenser.
13 . The system of claim 9 , wherein the substrate is moving with respect to the dispenser.
14 . The system of claim 9 , wherein the location is specified in terms of pixel values in the one or more layer files.
15 . A nontransitory computer readable medium having stored thereon instructions that, when executed by one or more processors, cause the processors to perform operations comprising:
transmitting colorant dispensing data to a colorant dispenser, the colorant dispensing data including:
one or more layer files each specifying a color of one or more pixels, and
one or more colorant recipes, each colorant recipe corresponding to a layer file, wherein the colorant recipe is generated based on one or more buildup curves associated with a combination that includes each of a substrate, one or more colorants and the colorant dispenser, the one or more buildup curves specifying optical characteristics of prints generated using the combination, each layer file and corresponding colorant recipe configured to be effective to cause the colorant dispenser to dispense a respective colorant of the one or more colorants onto the substrate at a location specified by each of the one or more pixels of each corresponding layer file.
16 . The nontransitory computer readable medium of claim 15 , wherein the colorant dispenser comprises:
a spectrophotometer coupled to the one or more processors; and
wherein the one or more processors are configured to dispense an amount of a chemical at a specified location of the substrate via the colorant dispenser and based on at least one of the one or more colorant recipes generated based on the one or more buildup curves.
17 . The nontransitory computer readable medium of claim 16 , wherein the chemical is the colorant.
18 . The nontransitory computer readable medium of claim 16 , wherein the amount of the chemical is determined based on a colorant recipe of the one or more colorant recipes determined responsive to a spectral measurement from the spectrophotometer.
