Custom Packaging Printing 101: Flexo, Digital & Rotogravure Explained
Why Printing Method Matters
The printing method you choose affects color accuracy, minimum order quantities, cost per unit, and lead time. Understanding the three main printing technologies — flexographic, digital, and rotogravure — will help you make the right choice for your brand's needs and budget.
Flexographic Printing
Flexographic (flexo) printing uses flexible rubber or photopolymer plates to transfer ink onto the film. It's the most common method for flexible packaging, offering excellent color consistency, fast production speeds, and competitive pricing at medium-to-high volumes. Flexo supports up to 8–10 colors and works well on most film substrates. Typical MOQ starts at 3,000–5,000 units, and plate costs range from $500–$1,500 per color.
Digital Printing
Digital printing transfers artwork directly from a computer file to the film without physical plates. This makes it ideal for short runs, product testing, and frequent design changes. MOQ can be as low as 100–500 units with no plate fees. However, digital printing has limitations: it's generally more expensive per unit at high volumes, and color gamut on metallic or dark substrates can be narrower than flexo or rotogravure.
Rotogravure Printing
Rotogravure (roto) uses engraved cylinders to apply ink with exceptional precision and consistency. It produces the finest detail, smoothest gradients, and most vibrant colors of any printing method. Roto is the preferred choice for premium brands and high-volume production runs (typically 50,000+ units). Cylinder engraving costs are higher ($800–$2,000 per color), but per-unit costs drop significantly at scale.
Finishing Options That Elevate Your Design
Beyond the base printing method, finishing treatments dramatically affect the perceived quality of your packaging. Matte lamination creates a sophisticated, tactile feel popular in premium markets. Gloss lamination enhances color vibrancy and provides a clean, modern look. Soft-touch coating adds a velvety texture that consumers associate with luxury. Spot UV selectively applies a high-gloss coating to specific design elements — logos, product names — creating visual contrast and depth.
Which Method Is Right for You?
Choose digital printing if you need low MOQ, fast turnaround, or frequent design changes. Choose flexo if you need 3,000–50,000 units with consistent quality at a reasonable cost. Choose rotogravure if you're producing 50,000+ units and demand the highest print quality. At FlexiPack, we support all three methods and can help you select the best option based on your volume, timeline, and quality requirements.
