AR-P16  COLOR BALANCE ADJUSTMENT  9 - 2

5) The display below is shown. Select A4 or 8.5" x 11" size paper,

and press the EXECUTE key.

The test pattern for adjustment is printed, and the adjustment
menu is displayed. 

Test pattern

(Note) Use paper of the same or nearest color as the background color

of the test chart (UKOG-0305FCZZ) as far as possible.

6) Collate the test chart (UKOG-0305FCZZ) and the test pattern

patch density.

Place the test chart on the printed pattern so that the printed pat-
tern can be seen from the cut sections. Put several sheets of white
paper beneath the printed pattern.

Find out the density point in the test pattern array 1 which lies
between the Lower Limit and the Upper Limit of the test chart (1).

Put a check mark on the density point found in the procedure
above.

If there is no density point which satisfies the above condition in
test pattern array 1, perform the following procedures.

• When the test chart (1) density is higher than the maximum den-

sity (+4) in the array 1:

→

 Put a check mark on "+4" in the array 1.

• When the test chart (1) density is lower than the minimum den-

sity (–4) in the array 1:

→

 Put a check mark on "-4" in the array 1. 

For densities of Test chart (2) to (12), perform the same procedure
as procedure 6).

7) Set the adjustment points (+4 to –4 on the right side) correspond-

ing to the density points (12 positions) marked with check mark on
the test pattern on the adjustment menu.
