Figure 45.shows
the CreoScitex Digital Target (SDT) after positive
exposure on a negative plate (the SDT after positive exposure is
similar). The numbers in below text refer to the numbers in figure.
In this area, each numbered section represents
one of the 24 diodes.
Each diode exposes a group of solid and dotted lines. If all these sections
appear equal, this means that all diodes are operating properly.
If only the solid lines appear, this may indicate a problem with
the diode driver.
Highlight areas with dot percentage ranging
from 0% to 5%.
Shadow areas with dot percentage ranging from 95% to 100%.
Target consisting of different shapes with
line thickness of 10µm (1P), for
positive and negative. To check intensity.
Check-patterned squares in 1P, 2P, 3P, 4P and
8P sizes. To check the focus, resolution,
intensity uniformity, and elevation.
Horizontal and vertical lines in 1P, 2P, 3P
and 4P thickness. To check resolution and
delay.
Squares with dot percentage from 0% to 100%,
in steps of 10%.
Lines and circles of various thickness. To
check resolution, delay, intensity
uniformity and elevation of the optical head.
Dot area to check uniformity, highlights and
shadows.
