9.2 Test Exposure for Simultaneous Adjustment of Laser Power and
Drum Rpm, or Focus and Zoom
The procedure for performing a test exposure for simultaneously adjust the laser
power and drum rpm, or focus and zoom, is explained here.
NOTE
• In the above screen, the values in parentheses above the initial values show the
drum rpm, laser power, focus, and zoom values in the media type selected when
the plate was loaded. Use it as a reference when performing the test exposure.
• The initial value is the first laser power and drum rpm (or focus value and zoom)
used in the test exposure.
• The increment value indicates the amount of the change from the initial value. For
example, if the laser power increment value is set to 10%, output will take place at
increments of 10% from the initial value.
• The count is the number of times the test exposure is to be carried out.
• The exposure start point is the distance from the plate edge to the point where the
test exposure begins. This value is updated (moved to the next possible exposure
position) each time a test exposure ends.
