Three Technologies, One Market
Flexible packaging is produced by three dominant printing technologies: CI flexography, rotogravure, and offset. Each has a distinct cost structure, quality ceiling, and production profile. Understanding where each excels is essential for converters choosing new equipment and brand owners evaluating supplier capabilities.
CI Flexographic Printing
Strengths
- Fastest plate-making and job setup — plates ready in hours vs. days for gravure cylinders
- Lower prepress costs — photopolymer plates cost a fraction of engraved gravure cylinders
- Compatible with both water-based and solvent-based ink systems
- Modern gearless CI flexo achieves gravure-comparable quality for most packaging applications
Typical Run Length
5,000 meters minimum to justify plate cost; most economical for runs of 20,000 meters and above.
Rotogravure Printing
Strengths
- Exceptionally consistent ink density over extremely long runs
- Outstanding halftone and shadow reproduction
- Reproducible results — a cylinder used today prints identically in 2 years
Limitations
- Cylinder engraving cost is very high ($800–$3,000+ per color)
- Long cylinder preparation lead time (1–3 weeks)
- Almost exclusively solvent-based inks — regulatory complexity
Typical Run Length
Minimum 50,000 meters to justify cylinder cost; most economical above 200,000 meters per design.
Head-to-Head Comparison
| Factor | CI Flexo | Gravure | Offset |
|---|---|---|---|
| Prepress cost | Low–Medium | Very High | Medium |
| Job changeover time | 30–90 min | 2–4 hours | 45–120 min |
| Min. economic run | 5,000–20,000 m | 50,000–100,000 m | Variable |
| Max print speed | 500 m/min | 400 m/min | 200 m/min |
| Water-based ink | Full support | Limited | Full support |
| Environmental compliance | Favorable | Challenging | Moderate |
The Industry Trend: CI Flexo Gains at Gravure's Expense
Global flexible packaging investment data shows new press investments overwhelmingly favor CI flexo over gravure. Shorter run lengths are the new normal — brands produce more SKUs and more frequent design updates. Modern gearless CI flexo presses now produce quality that satisfies brand owner requirements previously met only by gravure, at a dramatically lower per-job cost. Gravure retains its position only for ultra-high-volume packaging (200,000+ meters per design per year).
