This paper deals with the gap in undergraduate graphic design student prepress knowledge, and how addressing the shortfalls can lead to reduced waste through graduating designers that practice more informed reproduction. This paper follows the research for my master’s thesis (Lottering 2017) which emerged as a result of being required to teach prepress theory and finding that the amount of theory needed to be covered in the classroom was far too much and far too complex for students to fully understand given the available time allotted to teaching and learning on the topic. On an exchange trip to Sweden in 2014, my students were given the opportunity to print milk carton packs on an actual, industry standard flexographic press.
