Printing Methods for Corrugated Packaging: Flexo vs Digital

High-quality graphics are increasingly important for corrugated packaging, especially retail-ready packages and displays. Understanding printing options helps optimize specifications.

Flexographic Printing

How It Works

Flexible rubber or photopolymer plates transfer ink to the corrugated surface through direct contact.

Advantages

Fast production speeds

Low cost per unit for large runs

Wide range of ink options

Suitable for rough corrugated surfaces

Limitations

Plate costs for each design

Setup time for job changes

Minimum order quantities apply

Less detail than lithography

Best For

High-volume shipping boxes

Standard repeat designs

Cost-sensitive applications

Digital Printing

How It Works

Inkjet or electrostatic technology applies ink directly from digital files—no plates required.

Advantages

No plate costs or setup

Variable data printing possible

Quick turnaround

Economical for short runs

High-quality graphics

Limitations

Higher cost per unit on long runs

Slower production speeds

Equipment investment required

Best For

Short runs and prototypes

Personalized packaging

High-quality retail displays

Versioned packaging

Hybrid Approaches

Many converters use both technologies

Flexo for standard elements

Digital for variable elements

Pre-printed liner then corrugated

Impact on Adhesives

Printed surfaces may require adhesive adjustments as ink can affect bonding. Test adhesive compatibility with printed papers before production.
