FLEXO Magazine : February 2012
sequence is a testament to what FQC researchers were doing correct. Meticulous preparation went into each trial to avoid such unknown, unmeasured occurrences. Team members believe that addressing spitting with the preparation points listed above, as well as evaluating the spitting with the use of a matrix, helped isolate spitting to more identifiable causes for the converter. CONCLUSION FQC research has determined that while there is no uni- versal cure for UV spitting, a comprehensive effort in the form of a fingerprint is the prescribed method to understand the nuances of any particular situation. It is similar to the chal- lenges of uncontrolled process printing. Once you fingerprint and define variables, then you can progress to a workflow solution. FQC developed an effective method by using the matrix analysis that it hopes to see applied to similar situations, so the root cause can be better defined. The matrix method has been applied in the field and has netted positive results for those converters. FTA’s FQC team will remain in place and the customizable matrix will be available for any converter who chooses to run an analysis of the situation to help improve this process to eliminate a majority of spitting issues.
