Intro to Production Printing: Paper 101

Paper 101 – Episode Summary

In this foundational episode of The Print University, Pat McGrew and Ryan McAbee introduce viewers to the wide and often misunderstood world of paper and substrates. Perfect for onboarding team members through printing industry training programs for new employees or implementing printing technician certification online, this course explains why paper is more than just a material—it’s the fifth color of print.

The episode begins by explaining how only one-third of paper produced globally is used in printing, and how mill conversions to packaging stocks have created tighter supply chains. Printers are urged to “pick with a purpose,” choosing substrates based on application, longevity, finish quality, and environmental factors.

Ryan and Pat explore paper fundamentals like:

  • Uncoated vs. Treated/Coated stocks: absorption, cost, brightness, and color fidelity

  • Grain direction and how it affects folding, stitching, and converting

  • Basis weight vs. GSM and how to use mobile tools for conversion

  • Standard sizes and categories: bond, text, cover, index, rag, and book stocks

They also extend the conversation to non-paper substrates used in signage, vehicle wraps, and industrial applications—covering vinyls, aluminum, coroplast, and mesh fabrics. Environmental exposure, print method, and intended use dictate substrate choice, requiring coordination between print, finishing, and design teams.

Paper affects color, finishing, and cost—and understanding it empowers better print decisions across the board.

You Will Learn:

  • How to classify and select between uncoated, coated, treated, and specialty papers

  • Paper terms: grain direction, basis weight, GSM, dot gain, and substrate behavior

  • Common paper types and their use cases: bond, book, cover, index, rag, and envelope stocks

  • Why substrates matter for finishing, folding, mail, signage, and durability

  • How substrate choice impacts ink behavior, color quality, and total cost of production

Who This Course Is For:

New hires, prepress teams, designers, customer service reps, and production managers building printing technician certification online, print shop employee onboarding templates, or evaluating materials for digital printing press training
