What is the biggest source of paper waste in commercial printing?

The biggest hidden source is obsolete inventory. Ordering huge quantities to chase a lower per-unit price often backfires when the information on the piece changes, leaving thousands of now-useless copies to be discarded.

• New address, updated branding, or revised pricing can retire a full run overnight
• Large stockpiles tie up cash and storage space while they sit unused
• Smaller, more frequent orders usually cut both total waste and total spend
• A slightly higher per-unit cost is often cheaper than paying to print and then trash extras

Matching order size to your real distribution plan is the single most effective way to reduce printing waste.
