Operation of Test Print
5�2�3 How to Judge QC Pattern
When the QC patterns are printed, check the results. Make an assessment as to the printed QC pat-
terns by visually checking according to the items to be checked and readouts given by the densitom-
eter built into the main unit. If any one of the items does not fit, the results are judged as being “NG”.
Use the “Test Print Check List” (page 119) in Appendix B.
Visual Check of QC Patterns
Check the printed QC patterns according to the items to be checked shown below.

ance
(1) “Geometric pattern” as shown is printed
(2)
“Alphabetic/numeric characters” on the film image can be properly identified
(3) No “speckle noise” was created on all or part of the film image
(4) No “horizontal stripe” was created on all or part of the film image

Resolu-
tion
(9) The “horizontal thin line” of QC pattern appears to be resolved (A magnifying glass is used)*
(10)
The “vertical thin line” of QC pattern appears to be resolved (A magnifying glass is used)*
Note *: Instead of checking with a magnifying glass, if the density is “1 (left)” < “2 (middle)” < “3 (right)”, it is judged as
being “OK”.
