Abstract
A spectrophotometer diagnosis system and a method for diagnosing a spectrophotometer, wherein at least one test patch is printed in proximity to at least one non-printed substrate patch, at least one value characteristic of the at least one test patch and/or the at least one substrate patch is measured using the spectrophotometer, and at least one diagnostic score for the spectrophotometer is determined based on the at least one measured value in comparison with a reference value.
Claims11
A method for diagnosing a spectrophotometer, comprising:
- Printing at least one test patch, in proximity to at least one non-printed substrate patch,
- Measuring at least one value characteristic of the at least one test patch and/or the at least one substrate patch using the spectrophotometer,
- Determining at least one diagnostic score for the spectrophotometer based on the at least one measured value in comparison with a reference value.
A spectrophotometer diagnosis system comprising:
- A printer, configured to print at least one test patch, in proximity to at least one non-printed substrate patch,
- A spectrophotometer, configured to measure at least one value characteristic of the at least one test patch and/or the at least one substrate patch,
- A processing unit, configured to determine at least one diagnostic score for the spectrophotometer based on the at least one measured value in comparison with a reference value.
