Excurve Calibration 375. Develop the exposed test plates, use a densitometer to measure the dotpercentages of each test strip and record the results.To get accurate results, be sure to zero the densitometer to a ghost dotarea on the plate before measuring the dot area.If the measured values are within 2% of the corresponding file values,no further adjustment is required.If the measured values differ from the corresponding file values bymore than 2%, then you need to repeat the Excurve calibration fromscratch. Make sure that you accurately measure the values with thedensitometer, and increase the number of values in the table.Automatic Excurve VerificationYou can define specific time intervals at which the Excurve verification testis automatically performed. At these defined intervals, a test strip isexposed, based on the parameters defined by the Expose operation of thetemplate.To define automatic periodic tests:1. From the main Calibration dialog box, select the Periodic Test box.2. Click Make Test Every and select how often the test should be run.3. In the At boxes, type the hour (HH) and minute (MM) that the testshould run on test days.Modifying an ExcurveWhen an Excurve is no longer accurate, you should run an uncalibratedtest exposure (not based on an Excurve), measure the dot percentagevalues from the test strips with a densitometer, and type the newcoordinates into the Excurve table. You can either build a completely newtable, or modify an existing one.See Creating the Excurve on page 31.
