2 Visually check the 'QC ' test image for artifacts: no significant disturbing
artifacts should be visible.
3 Check the spatial resolution by examining the three squares, each of which
contains an oval. Within each oval are three groups, each having five dots. All
five dots of each group must be visible (use a magnifying glass and optimize
viewing conditions).
4 Record these values at the top of the Drystar 5300 Chart 3 (‘Drystar 5300
Artifacts and Spatial Resolution Control Chart’). Refer to Appendix C ‘Quality
Control Charts’ on page 199.
5 These charts will be used for the weekly quality test. For more information,
refer to ‘Performing the weekly QC test (Spatial Resolution and Artifact Test)’
on page 120.
In case of significant artifacts or insufficient spatial resolution, the
reason must be found and the problem solved before any further clinical
films can be printed.
Refer to ‘Maintaining optimal image quality’ on page 101 and ‘Preventive
maintenance’ on page 161, or call your local Agfa service organization.
