Calibration Workflow
To guarantee high-quality exposures, a unique laser intensity is required
for each plotting resolution.
•
If the laser intensity is too low, the exposure is too light and quality is
lost (that is, black areas are
not
uniform, and thin lines and small text
may disappear).
•
If the laser intensity is too high, thin lines may become too thick and
small text may be covered. In addition, the life of the laser is shortened.
To calibrate laser intensity, perform the following steps for each
exposure resolution:
1.
Prepare exposure strips.
2.
Set an exposure resolution for the strips.
3.
Expose the strips.
4.
Use a densitometer to measure the density on the exposed strips of
film. Write down on paper the intensity used to expose the requested
density max of film at
each
resolution.
5.
Record the new laser intensity values. Enter the intensity for each
plotter resolution into the Resolution Intensity Table.
6.
Save the new laser intensity as a standard.
