Running a QC Baseline Test
This test sets up a baseline set of film parameter values which will be used as a standard for
comparison in daily quality control tests. The baseline test must be run when the 8600 is first
installed, and it must be repeated every time a box of film with a different emulsion number is used.
1. Apply power to the 8600 and allow it to warm to READY, as indicated on the local panel. The
8600 will print a film calibration sheet, to put its Automatic Image Quality Control (AIQC) system in
control.
2. Print a QC Step Wedge test film. ( Refer to page 5-15 in the User Guide for the procedure. See
the illustration below for a sample step wedge,)
3. Repeat printing QC Step Wedge films until you have accumulated five test films.
4. Using a densitometer, read and record the density of each step (1 through 21) on each of the five
test films. (For consistency from film to film, always read density at the center of each wedge.)
5. Determine and record the average of the five densities read for each step.
6. Select from the average values calculated from the 21 steps to determine the film parameter
values as described on the next page.
7. Determine which step has a density closest to 2.20. Then determine which step has a density
closest to but not less than 0.45. Designate the difference between these densities as Density
Difference (DD).
8. Determine which step has an average density closest to 1.20. Designate this step as Medium
Density (MD).
9. Designate the average for Step 1 as Laser Film Minimum Density (LFMD).
10. Record the numeric values of DD, MD and LFMD on the center lines of the Laser imager QC
Chart. (See Figure 5.) Record also the step numbers involved.
