The Print Shop's Guide to AI Prepress

Everything here was learned inside a working Minuteman Press and baked into our engine. No fluff, no stock photos of handshakes — the actual rules, math, and rituals of files that print right.

Preflight
The 7 things wrong with almost every customer file

RGB, fonts, bleed, hairlines, soft images, overprint, wrong sizes — and the real fix for each.

Imposition
Imposition, explained like you're at the counter

The fit math, gutters and margins, crop mark conventions, and why utilization is the money number.

Booklets
Reader pages, printer spreads, and spine creep

The pairing rule, multiples of four, creep compensation, and digital vs offset plating styles.

Bleed
Why 0.125" exists — and rescuing files that have none

Cutter tolerance, safety margins, and the edge-mirroring technique that saves customer files.

EDDM
Size rules, the indicia, and passing at the counter

The exceed-6.125" flat rule, why 6.25×9 is the standard, and the paperwork that gets reorders.

Work orders
How to write a work order anyone can run

The six facts every ticket needs — for a new hire or an AI. The good ones are identical.
