Plan on about 60 shirts an hour from each live printing press. The standard station we drive up from La Habra has two presses and two printers, good for 100+ an hour when the queue stays full. Each guest waits about two minutes for theirs.
Real output lands under that ceiling for ordinary reasons. Four colors take longer than one. Guests who stop to debate a size slow the press. Personalized work at a tech crowd, a GitHub handle or a team name on every shirt, runs through DTF, and each of those is its own little print job.
Sizing live printing to a San Francisco crowd
- An offsite, an all-hands or a SOMA launch party: one two-press station usually carries it.
- A few hundred people who all arrive at once: we add a press or a second station so nobody waits out the whole reception.
- 400+ guests or a tight window: multiple stations, which is what a busy Moscone expo booth or a Fort Mason festival weekend calls for.
Timing beats totals. Expo hours at Moscone Center send a steady trickle all day, and that trickle is what justifies the second press. A Union Square hotel reception comes up in bursts between speeches. A concert at Bill Graham Civic Auditorium hits hard at doors and again after the encore, so we fold sizes ahead of time and run flat out in those two windows. Send your headcount and station hours and we'll spec the presses.
Where a San Francisco live t-shirt printing line gets stuck
The press is rarely the hold-up. People stop at the design board, then again at the size wall deciding between a medium and a large, and that's where the line grows. At about two minutes a shirt and 100+ an hour from one two-press station, 200 attendees cycling through a Moscone booth clear in roughly two hours. A Chase Center suite works differently, since most guests show up in the hour before tip-off and all want a shirt before the game starts, so that one gets a second press. Outdoors at Fort Mason or Golden Gate Park, the summer fog and wind off the bay mean weighted canopies and stock kept in bins, not stacked on a table. Live embroidery and the hat bar in San Francisco run on their own lines, so count those guests separately. The truck leaves La Habra the day before with the presses we agreed on, and there's no going back for another, so settle the count before then.
