Curve Pilot understands dot gain measurements in a number of units. These are summarized in the Table below.
| Unit | Min Val | Max Val | Description | Application Notes |
|---|---|---|---|---|
| density | 0 | na | The optical density of reflected light | Use a densitometer set to the desired density filter for your region / specifications (see also Curve Pilot Preferences) |
| %DotArea | 0% | 100% | The amount of reflected light from a screened area, compared to paper and solid | Use a densitometer that can calculate %DotArea using the Murray-Davies equation |
| ΔE-P | 0 | na | ΔE-P is a colorimetric measurement indicating the color difference between a colored/inked patch and paper | Use a spectrophotometer with ΔE calculations set to CIE-1976 or more recent standard (see also Curve Pilot Preferences) |
| %ΔE-SP | 0% | 100% | %ΔE-SP is a colorimetric measurement indicating the color difference between a colored/inked patch and paper, proportional to the color difference between solid and paper | Use a spectrophotometer with ΔE calculations set to CIE-1976 or more recent standard (see also Curve Pilot Preferences) |
