Abstract
A device that determines conditions under which a web break is more likely to occur in a printing system stores data pertaining to ink temperature or ink temperature gain. The device then implements a correlation analysis, such as a decision-tree induction analysis, using the stored data to determine if there is a correlation between the one or more attributes and the occurrence of a web break. The device has a multiplicity of ink fountains and includes a first temperature sensor that measures a first ink temperature and a second temperature that measures a second ink temperature. A controller compares the first ink temperature to the second ink temperature to determine an ink temperature gain, compares the ink temperature gain to a desired ink temperature gain range and generates an output signal based on the comparison.
