To control the quality of the printing and packaging that accompanies its musical instrument accessories, D'Addario relies on its in-plant.

In addition to packaging and print advertising, the D'Addario in-plant prints catalogs, stationery, music writing paper (in both book form and single sheet) and posters. Equipment in the prepress department includes a Harlequin RIP driving a Heidelberg Suprasetter platesetter and processor. The pressroom features a four-color, 29˝ Heidelberg SM74 press, a two-color Heidelberg SM52, a one-color Heidelberg GTO, and a one-color Halm Jet press. The bindery includes a single-fold Baum folder, a Polar cutter, a James Burn Wire-O punch, plus scoring, perforating and drilling equipment.
