The target audience for these courses are all those who have to operate a printing press and need to understand what is happening on the press and the factors that affect the performance of the process.

Initial research has indicated that people who consider themselves as competent typically score 40% in knowledge tests. The aim is to increase this level of retained knowledge to better than 85%. Supervisors score slightly higher than operators but managers often lower. This shows that everyone will benefit from the course. It may be that individuals might wish to select particular lessons without aiming for full Certification.

The lessons are applicable to every learner no matter what their specialist sector. The intention is to give the learner an understanding of other screen printing methods as well as the aspects of the process that are common to all.

There are lessons that go into the specifics of particular systems and techniques used in the various sectors.
