Print estimates drift from actual costs because quotes use averages while jobs use real sheets. The gaps usually open in make-ready waste, spoilage through finishing, outsourced work priced late and stock bought at a different price or size. Compare estimate and actual line by line on finished jobs to see which gap is yours.
Make-ready waste is quoted as a flat number
Most estimating tables add a fixed allowance of sheets for make-ready, yet real make-ready varies with the press, the operator and the job. A tight register on a four-colour sheet, a stubborn spot colour or a heavy solid can burn far more paper than the table assumes.
Short runs suffer most. So do jobs on heavy board. On a run of a few hundred copies, waste sheets are a large share of the paper you bought, and the estimate never saw them coming.
Digital work has the same problem in another form, because test prints, colour calibration and stock loading eat machine time that the click charge never covers. Nobody writes that time down.
- Waste allowance set per press, not per shop
- Heavier allowance for solids, tight register and spot inks
- Test prints and calibration on digital jobs
- Operator and shift recorded against make-ready time
Spoilage compounds through finishing
Every stage after the press loses sheets. A folder spoils sheets while it is set, a guillotine trims out scuffed stock, and a binder rejects a few books during setup. An estimator who adds one allowance at the press and none for the folder, guillotine or bindery will run short on any long job.
Spoilage works as a chain. Every link depends on the one before it, so if the press delivers just enough sheets, one fold problem at the folder means reprinting part of the order.
Log spoiled counts per stage. After a dozen jobs of one type, the allowance for each stage becomes a known number instead of a guess made once and never revisited.
Outsourced finishing is priced late and changes
Foil blocking, embossing, die cutting and perfect binding often go to trade suppliers, and the estimator quotes from the last rate card in the drawer. The supplier then adds a tooling charge, a minimum run fee, a courier leg or a rework after a failed first pass.
Delay carries its own cost. A job that sits at the bindery for two extra days holds up the next delivery and may force a rush on the guillotine.
Get a written price from each supplier for each job type and keep it beside the estimate, so the invoice has something to be matched against. Query every difference before you pay.

- Tooling, setup and minimum run charges listed
- Courier and return transport included
- Date sent, date due and date back
Stock price and sheet size move between quote and purchase
The paper price may be weeks old. Mills revise lists. Merchants run out of a grade such as 130gsm gloss art, and the substitute arrives in a sheet size that changes the grain direction and the waste pattern.
Minimum orders add another layer. If the job needs a few thousand sheets and the merchant sells by the pallet, the leftover stock sits on the shelf or gets absorbed by the job.
A quote that never sees the merchant’s invoice is working blind, so the real price and sheet size must be recorded on the job itself.
Close the gap with a variance line on every job
Set estimate beside actual for stock, press hours, finishing and outside work, and the difference per line is the variance that every later quote should learn from. One job tells you little. Twenty similar jobs reveal a pattern.
Review variances each week. Where the same line is short again and again, change the allowance in the estimating table, and where one supplier always lands higher, quote from their latest list.
Pick ten finished jobs of one type. Mark the gap that hurt each most.
Estimate versus actual variance sheet
A single worksheet gives each finished job its own row and each cost line its own column. The columns are stock, make-ready sheets, run spoilage, finishing hours, outside supplier, delivery and total. Each column holds estimate, actual and difference. A last column names the main cause, such as loose register, substitute stock or supplier surcharge.

How much make-ready waste should I allow?
There is no shop-wide answer, because it depends on your press, the job type and the operator. Record spoiled sheets on twenty or more jobs per press, then set the allowance from that history. Review it each quarter.
Should I quote with a safety margin instead?
A margin hides the pattern without fixing it. You lose jobs on price where the margin is wasted, and you still lose money where the real gap is bigger. Fix the allowances first.
Who should record actual costs?
The people who touch the job. Operators log sheets and times, the store logs stock issued, and purchasing logs supplier invoices against the job number so nothing is estimated after the fact.
How often should estimating tables be updated?
Review them after a batch of finished jobs, and again whenever a paper price, a press or a finishing supplier changes. A quarterly check suits many shops.
