Evaluating a Test Page

After you process the exposure test page, read and evaluate it. Use a
densitometer to measure the density and determine which exposure is
the best for your purposes.

How to Read a Test Page

To read the exposure values for each band on a test page, hold the
page with the reference band indent to the left and the increment
value indents to the right. See Figure 3.5.
The imagesetter follows this pattern to select exposure settings for
each band on the test page:
Higher exposures toward the top of the page...
Step +3 = current exposure + (3 x increment value)
Step +2 = current exposure + (2 x increment value)
Step +1 = current exposure + (1 x increment value)
Reference band (current exposure)
Step -1 = current exposure - (1 x increment value)
Step -2 = current exposure - (2 x increment value)
Step -3 = current exposure - (3 x increment value)
Lower exposures toward the bottom of the page...
