WASTE: unusable sheets
that don't count toward the total number of impressions required for
the press run.
• Waste is anticipated and "excusable" because every job
has to be brought up to color on a running press. Test sheets must be
pulled, examined, discarded and/or filed.
• Waste also occurs in the bindery. Every job has a
"waste allowance" that is factored into the cost of the paper purchased
for the job. Obviously, the printer should not permit the waste to
exceed the waste allowance.
SPOILAGE: paper discarded
because of poor planning, production mistakes, faulty quality control.
Spoilage is never "excusable."
• According to Printing Industries of America, sheetfed
printers have an average spoilage rate of 3 percent based on sales.
Cutting spoilage can improve printers' profits dramatically.
OVERS/UNDERS: Because of
production variables, the total number of finished, deliverable printed
pieces seldom matches the quantity ordered. It could be more, or it
could be less.
• Therefore, an allowance for overs and unders should be
built into the run length requirement for every job.
• Printing industry trade customs specify that over- and
under-runs should not exceed 10 percent of the quantity ordered, and
that printers may charge extra or give credit for amounts outside this
range. (These terms are subject to negotiation.)
