Quality

The "Quality" tab offers several quality reports of a selected operation.

•Operation Quality "Summary"
This report shows two evaluations:

·The OK sheet is compared with the wet ink set of the measuring device and assessed with regard to the deviations to the print standard.

·The production run sheets are compared with the OK sheet and assessed with regard to the deviations to the print standard.

•Operation Quality "Progress"
This report shows the measurement results over the entire print duration as they are visible to the operator of the colorimeter.

•Operation Quality "Zone Evaluation"
These reports contain the average, the maximum and the minimum Delta E, density and dot gain value for each ink zone.

Requirements

To analyze the quality data, the following prerequisites must be met:

Quality report / Measuring Device	Prinect Image Control I	Prinect Image Control II	Prinect Inpress Control & Prinect Axis Control II	Prinect Axis Control I
Summary	Not supported	I13A and later	S12B and later	Not supported
Trend: Density, Delta E	V5.1 and later	I11A and later	S10A and later	Not supported
Trend: Dot gain	V5.1 and later	I11A and later	S11B and later	Not supported
Trend: Paper white	No restriction	I13A and later	S12B and later	Not supported
Zone analysis: Density, Delta E	V5.1 and later	I11A and later	S10A and later	Not supported
Zone analysis: Tonal value	V5.1 and later	I11A and later	S11B and later	Not supported

Why are measured values not shown although current software versions are present?

Storage period of the color reports exceeded

If measured data should not display despite the latest software versions, it is possible that they were already deleted from Analyze Point. See Storage Period of Reports.

Special features with Prinect Inpress Control

With Prinect Inpress Control, measured data for dot gain may not be available for an operation. In this case, the last available measured data for dot gain are shown in the diagram. The reasons for no measured data may be:

•It is a short production run.
Prinect Inpress Control measures quality every 400 sheets, and in short production runs quality may not be measured during an operation.

•Dot gain was not measured by the machine operator.
When quality is measured, the machine operator must enable dot gain measurement manually. As of V14B, the operator can enable "Apply measured value for dot gain" so that dot gain is measured automatically.
