Printing units form the core of offset presses, housing plate cylinders, blanket cylinders, impression cylinders, and inking/dampening systems. They transfer ink precisely to substrates, ensuring accurate registration, uniform ink laydown, stable pressure, and high-quality output at maximum production speeds.

Maintenance involves checking cylinder bearings, gear alignment, and pressure settings daily, alongside cleaning blankets and plates. Common issues include bearing wear, gear pitting, blanket swelling, and packer deformation. Replacement is advised when registration drifts, pressure inconsistencies arise, or surface damage causes print defects and downtime.
