Method for controlling retroreflectivity by application of opaque and transmissive agents to a retroreflective film and sheeting produced thereby

A system for controlling retroreflectivity in retroreflective sheeting, the system comprising:

• a supply of retroreflective sheeting having an initial performance level;
• a first data set having a plurality of particular performance standards;
• a second data set containing a plurality of patterns and overlay combinations used for manipulating the supply of retroreflective sheeting to provide for the particular performance standards;
• a distribution request setting forth a particular retroreflective performance standard contained within the first data set;
• a manufacturing module for using at least one of the plurality of patterns and overlay combinations to change the initial performance level of the supply of retroreflective sheeting to the particular performance standards set forth in the distribution request;
• and
• a measurement tool for measuring the modified performance standard of the supply of retroreflective sheeting to the particular performance standards of the distribution request after utilizing the second data set to manipulate the supply of retroreflective sheeting.
