Intro to Prepress Workshop

Overview

New to printing? Designing for print? This three-day workshop* is geared towards graphic designers and artists who are either working as prepress operators or designing for print. The workshop starts off with attendees going on press to print a job, where they will learn about platemaking, ink formulation, press basics and more. Print samples will be analyzed and measured. For the remainder of the workshop, go hands-on with the tools available in Adobe Photoshop, Illustrator and other prepress software needed to prepare artwork for printing. On the final day, after adjusting the art, go back on the press to see the result of good prepress work.

*A working knowledge of Adobe Illustrator and Photoshop is required!
