Abstract
In example implementations, a method and system of color calibration adjustment are provided. The system includes a printing system having an output; an ink drop weight (IDW) sensor connected to the printing system; a spectrophotometer connected to the printing system; and a processor connected to the printing system, the ink drop weight sensor, and the spectrophotometer to determine an effective ink drop weight (elDW) and modify the output of the printing system based on differences in the elDW (AelDWs) between a previous reference state of the printing system and a current state of the printing system.
Claims15
A method of adjusting color calibration, comprising:
- detecting a plurality of sets of ink drop weights;
- and
- adjusting color calibration based on a comparison of the plurality of sets of ink drop weights and a plurality of sets of effective ink drop weights.
A color calibration adjustment system, comprising:
- a printing system having an output;
- an ink drop weight (IDW) sensor connected to the printing system;
- a spectrophotometer connected to the printing system;
- and
- a processor connected to the printing system, the ink drop weight sensor, and the spectrophotometer to determine an effective ink drop weight (eIDW) and modify the output of the printing system based on differences in the eIDW (ΔeIDWs) between a previous reference state of the printing system and a current state of the printing system.
