Establishing the reference values and verifying image quality
After installation of a new printer and before initial use you must establish
Quality Control aim values. These values will be used as the base line for
comparison when daily Quality Control is done. These values should be
determined again after major service, repair or software update.
The following Quality Control aim values must be determined:
• The daily operating density levels.
• Image geometry.
Once Quality Control aim values are established you must evaluate the Spatial
Resolution, the Artifact Levels and the Low Contrast Visibility to determine if
the image quality is acceptable.
The Quality Control aim values, the Spatial Resolution and Artifact Levels and
the Image Geometry values are all recorded on the Quality Control charts.
On these charts, the following test conditions are also recorded:
• The type and serial number of the printer.
• The type and emulsion number of the film used to determine the reference
values.
• The type of densitometer used.
• The time (day, month, year) that the values were established.
WARNING:
Before you can establish the daily operating levels, the printer
must be switched on for at least 15 minutes and it must be
calibrated as well.
