Ricoh Gen6 vs Gen5 for Packaging: Is MH5320 Worth the Upgrade?

Compare Ricoh Gen6 MH5320 and Gen5 MH5421 printheads for packaging applications. Review speed, ink compatibility, and long-term operating differences based on official specifications.

Quick Decision Guide

• Running aqueous ink on paperboard at moderate speed (<50 m/min) → MH5421 remains applicable
• Running UV or solvent ink on film, foil, or labels → MH5320 is required
• Targeting high-speed production (>60 m/min) → MH5320 offers better stability
• Designing new industrial systems → Gen6 is the current platform

Why This Comparison Matters in Packaging

In packaging printing, performance is defined by:

• Stable jetting over long production runs
• Compatibility with multiple substrates
• Reduced maintenance and downtime

The transition from Gen5 to Gen6 is not only about higher frequency, but also about ink flexibility and system reliability.

Speed & Throughput in Continuous Production

Practical Impact:

• Higher frequency allows fewer passes at the same coverage
• Smaller droplets improve edge sharpness on labels
• Higher temperature tolerance improves stability in industrial environments

Ink Compatibility & Substrate Range

Practical Impact:

• Gen5 is limited to absorbent substrates
• Gen6 supports non-porous materials via UV inks
• Enables expansion into labels, flexible packaging, industrial marking
