A prepress technician is the person who makes sure a design will print correctly before any ink touches paper. You take files from designers and clients, check fonts, images, colors and sizes, fix problems, make proofs, and send clean files (or plates) to the press. Why it matters: a mistake caught at prepress costs minutes; the same mistake on press costs thousands of dollars and days. This roadmap takes you from knowing nothing about print to being the person a shop trusts with its toughest jobs. No degree is required (39% of workers have a high school diploma, 23% an associate degree). What

Stage 1 of 3 · about 10 weeks
Understand how print works and use InDesign, Photoshop, Illustrator and Acrobat well enough to build and inspect a simple print-ready file.
Print basics: color, resolution and paper
Every prepress decision comes from how ink sits on paper. Screens use RGB light; presses use CMYK ink. A photo that looks vivid on screen can look dull in print if you do not understand the difference. Knowing this lets you explain problems to clients.
Adobe InDesign page layout
InDesign is the main tool for building and fixing multi-page print documents. Prepress workers adjust text, position images, and set up pages every day, so you need to move around it fast.
Typography and proofreading
Your job includes proofreading text and images. Wrong fonts, bad line breaks, widows, orphans and missing characters are the errors clients notice first.
Acrobat and PDF basics
Nearly every job reaches the printer as a PDF. Acrobat is where you check fonts, color spaces, and page boxes, and it is on the O*NET software list for this role.
Print math and measurement
You will convert between points, picas, inches and millimeters, scale images, and calculate percentages of ink coverage. Mistakes in math produce wrong-size files.
