| Calibration |
Must be done for each quality separately.
Can be cumbersome with frequent quality changes. |
Sufficient to do for a group of similar qualities. Easier with frequent quality changes. |
Repeat quality -
calibration |
Could solve the issue of frequent calibration. |
Not needed. |
Accuracy with low
B/W base paper |
Accuracy is maintained. |
Accuracy low. |
| TRADE-OFF |
Accuracy maintained with all base paper qualities.
High color sensitivity with dark colors.
Calibration difficult with frequent quality changes.
Less expensive than microwave. |
Accuracy lost with low B/W papers.
Insensitive to colors.
Calibration not an issue with frequent quality changes.
More expensive than NIR. |
