Running Exposure Tests
Before you begin production, execute and evaluate exposure tests to
determine the optimum exposure setting for each resolution. To main-
tain high quality standards, repeat this procedure at regular intervals.
These are the basic steps of the procedure:
1. Execute a test page from the control panel.
2. Process the medium.
3. Evaluate your results.
4. Set the exposure value.
When to Image a Test Page
Image a test page:
• When you first use a new imaging medium. (For example, when you
first change from film to plate.)
• When you change emulsion batches. (The product label attached to
each case and each roll of Agfa photographic media is stamped with
a number that identifies the emulsion batch.)
• When you load a new roll of media or when you replace the chemi-
cals in your media processor.
• When you change processing conditions (new processor, different
type of chemistry, and so on).
• At some regular interval (daily or every other day) to ensure quality
control.
Note: Run separate exposure tests for each reso-
lution setting. The optimum exposure value varies
for each one.
