You're running two presses, the schedule's full, and everyone looks productive. Revenue's up. Profit isn't. That gap is not bad luck. It's math nobody in your shop has run yet.
What's Actually Happening: Value Per Hour
I coined a term for this: Value Per Hour. It answers one question. How much value does your shop create for each hour of productive work?
Not how many shirts you printed. Not how full the schedule looks. Just revenue divided by the hours it took to make it.
The Number That Changes Everything
Picture two production days on the same press, same 7.5 hours.
Day one: 10 orders of 24 shirts at $15 each. Total revenue $3,600. Value Per Hour: $480.
Day two: 3 orders of 1,000 shirts at $7.50 each, half the price per shirt. Total revenue $22,500. Value Per Hour: $3,000.
Same press. Same hours. Six times the value.
That press didn't get faster. The work routed to it changed. Everything downstream, staffing, pricing, which jobs you chase, depends on knowing which day you're actually running.
Why This Stays Hidden
For years, volume covered for you. Enough big orders came through and inefficiency got absorbed without anyone noticing. Busy presses felt like proof the business was fine.
That safety net is gone. Supply costs are up. Labor costs are up. And the work mix has shifted toward smaller, faster, more customized jobs, the kind that eat production hours without paying for them the way volume used to.
You're probably still routing work by habit, not economics: whichever press is open gets the job, whether or not it belongs there. You can't fix a routing problem you've never measured.
Do This Before You Do Anything Else
Pull yesterday's production data. Just yesterday. For every order that ran:
- Order size
- Decoration method
- Estimated labor time
- Total revenue
Divide the day's total revenue by the day's total labor hours. That's your Value Per Hour for yesterday. If most of what ran doesn't look like the shop you think you're running, you've found your identity drift, and identity drift is expensive.
Where I Go Deeper
I walk through the full routing logic, and how to run this across 30, 60, or 90 days instead of one, in Part 2 of "Leveling Up: From Identity Crisis to Competitive Advantage" for Impressions Magazine. Read the full piece →
Run Your Own Numbers
I built the Shirt Lab Value Per Hour Calculator so you can test this with your actual shop's numbers instead of mine. Start with yesterday. Then decide if you like what the math tells you.

If your shop stayed exactly this busy for the next year, would your bank account look any different?
