(c)
Locate density set from table. Density set is the difference between ideal 50% density and step which test
negative had 50% dot. Determine the density set as follows:
If ideal gray scale step is 16, with measured density of .52, test negative had a 50% dot in step 14 with density reading of
.42 or :
Step 16 = .52 density
Step 14 = .42 density
.10 difference
Above problem indicates a new exposure is needed that will produce a negative that
will move the 50% dot to a point with a .10 density higher on gray scale.
(d)
Find column marked +.10 on compensation table.
(e)
Place small record pad with arrows lined up with heavy lines on
(f)
Record unit numbers opposite previously circled numbers in blank column on right side of pad
(numbers should be 504, 50, and 1).
(g)
Add recorded numbers (total should be 555). This becomes the new MAIN UNITS setting and will
place the 50% dot at the appropriate .50 density step of gray scale.
(12)
To establish time units setting for highlight no-screen exposure, proceed as follows:
(a)
Set in approximately 6% of MAIN UNITS on HIGHLIGHT dials.
(b)
Make an exposure test; check for desired highlight dot.
