NOTE
• When performing a test exposure, the settings for the media type registered in the
data that is selected when the plate is loaded are used for settings other than the
initial value, increment value, and count (in the case of a laser power test
exposure, the drum rpm, focus value, and zoom value settings).
• To set the initial value, increment value, count, and exposure start point, refer to
“Table 5-1 Input ranges” and set the values paying attention to the following
points:
• The initial value must be equal to or more than the minimum limit.
• [Initial value + increment
×
(count - 1)] must be equal to or less than the
maximum limit.
• [Test exposure start point + 35
×
(count - 1)] must be equal to or less than the
horizontal size of the plate.
