Lotem^® 400 family

Symptoms

When exposing a positive excurve with positive plates, the excurve correction results mirror the required results.
For example, when measuring the grayscale percentage for 0-100 on each block and applying a correction table to the excurve menu, a correction of 2% shows on the 98% block.

Cause

The positive excurve is incorrect.
The correct way to work with positive plates is to use a negative excurve.

Solution

1. In the Edit Excurve dialog box, click the Auto Select Parameters button, as shown below.
   
2. In the Autoselect dialog box, under the Output section, select Negative, as shown below.
