Printing Services Procurement: Offset, Digital and Color Difference Control
AI Summary: The choice of printing method depends on quantity, lead time, paper and variable data requirements. Offset printing suits large volumes with stable color, while digital printing suits small batches, fast turnaround and variable content. Procurement should verify paper, color values, proofing, binding and color difference standards, and avoid using screen colors as the basis for acceptance.
