Abstract
Apparatus, methods, and systems for dynamically modulating radiation energy in a printing system are disclosed. A system receives data comprising an image pattern for depositing ink on a substrate. The system determines one or more ink properties for the ink configured to be deposited onto the substrate. The ink properties and/or a color of the substrate are used to determine a corresponding energy level value for a radiation lamp. The ink is deposited in the image pattern on the substrate. One or more radiation lamps heat the substrate and the ink, wherein the radiation lamps are configured with the corresponding energy level values.
Claims20
A method for dynamically modulating radiation energy in a printing system, the method comprising:
- receiving, by the printing system, an image pattern for depositing ink onto a surface of a substrate to print the image pattern on the substrate,
- wherein the image pattern comprises a plurality of segments corresponding to a plurality of areas on the surface of the substrate;
- determining, for each segment of the plurality of segments of the image pattern, one or more ink properties of a corresponding portion of the ink to be deposited onto a corresponding area of the plurality of areas on the surface of the substrate;
- for each segment of the plurality of segments of the image pattern, determining, based on the one or more ink properties of the corresponding portion of the ink to be deposited, a corresponding energy level for a respective radiation lamp of an array of radiation lamps to dry the corresponding portion of the ink,
- wherein at least one dimension of the array of radiation lamps corresponds to the plurality of segments of the image pattern;
- depositing, by a mechanism of the printing system, the ink according to the image pattern onto the surface of the substrate;
- configuring each radiation lamp of the array of radiation lamps to provide the corresponding energy level to the corresponding area on the surface of the substrate;
- and
- radiating, using the array of radiation lamps, the ink deposited onto the surface of the substrate to dry the ink.
A printing system, comprising:
- a mechanism configured to deposit ink to print an image pattern onto a substrate;
- one or more radiation lamps;
- and
- one or more processors coupled to the mechanism and the one or more radiation lamps, the one or more processors configured to:
- receive the image pattern for depositing the ink onto the substrate;
- determine a color of the substrate;
- determine, based on a color of the substrate, an energy level for the one or more radiation lamps to dry the ink on the substrate;
- cause the mechanism to deposit the ink onto the substrate;
- and
- configure one or more radiation lamps to provide the energy level to the substrate to dry the ink.
A non-transitory, computer readable medium for optimizing energy consumption for a printing system, the medium storing instructions that, when executed by one or more processors, cause the one or more processors to:
- receive an image pattern for depositing ink onto a substrate to print the image pattern on the substrate,
- wherein the image pattern comprises a plurality of segments corresponding to a plurality of areas on the substrate;
- for each segment of the plurality of segments of the image pattern:
- extract a feature vector from each segment of the image pattern, wherein the feature vector is indicative of one or more colors of a corresponding portion of the ink to be deposited onto a corresponding area of the substrate, and
- determine, using a trained model based on the feature vector, a corresponding energy level for a respective radiation lamp of one or more radiation lamps to dry the corresponding portion of the ink;
- cause a mechanism of the printing system to deposit the ink according to the image pattern onto the substrate;
- and
- cause each radiation lamp to provide the corresponding energy level to the corresponding area on the substrate to dry the ink.
