Image Adjustment 
D086/D087 4-12  SM 
 
3 
Shadow (High ID) 
(K, C, M, and Y) 
Adjust the offset value so 
that the density of level 8 
matches that of level 8 on 
the C-4 chart. 
4 
Highlight (Low ID) 
(K, C, M, and Y) 
 
Adjust the offset value so 
that dirty background does 
not show on the copy and 
the density of level 3 is 
slightly lighter than that of 
level 3 on the C-4 chart. 
5 
K Highlight (Low ID) 
(C,M, and Y) 
<on the full color 
copy> 
Adjust the offset value so 
that the color balance of 
black scale levels 3 through 
5 in the copy is seen as gray 
(no C, M, or Y should be 
visible). If the black scale 
contains C, M, or Y, do steps 
1 to 4 again.
