When you order custom printed bags, one of the first questions a manufacturer will ask is how many pieces you need. That number usually decides which printing method makes sense: digital printing or rotogravure (gravure) printing.
Both can produce sharp, full-color pouches. But they work in very different ways, and choosing the wrong one can mean paying too much per bag — or waiting weeks for a run you didn’t need. This guide explains the difference in plain terms so you can plan your next order with confidence.
How Gravure Printing Works
Gravure is the traditional method for flexible packaging. Each color in your design is engraved onto its own metal cylinder. Ink fills the tiny engraved cells, and the cylinder transfers it onto the film at high speed.
What this means for you:
- One-time cylinder cost. Every color needs a cylinder, so a 6-color design needs 6 cylinders. This is a setup charge you pay once; the cylinders can be stored and reused for repeat orders with the same artwork.
- Higher minimum order. Because of the setup work, gravure only becomes economical at larger volumes — typically several thousand to tens of thousands of bags per design.
- Lowest unit price at scale. Once the cylinders are made, the cost per bag drops sharply as quantity rises.
- Excellent, consistent color. Gravure delivers rich solid colors, smooth gradients and very stable color from the first bag to the last — and from one reorder to the next.
- Special inks and effects. Metallic inks, white underprint on clear or foil film, and precise Pantone spot colors are straightforward.
How Digital Printing Works
Digital printing sends your artwork directly from a computer to the press — no cylinders or plates. The press builds the image from process colors, much like a very advanced office printer designed for packaging films.
What this means for you:
- No cylinder cost. Setup is minimal, which makes small runs affordable.
- Low minimum order. You can order a few hundred or a few thousand bags instead of committing to a large run.
- Multiple designs in one order. Printing several flavors, SKUs or seasonal versions is easy, because changing the design costs almost nothing.
- Faster turnaround. Without cylinder engraving, samples and production can start sooner.
- Higher unit price. The cost per bag stays relatively flat, so digital becomes more expensive than gravure as volume grows.
Side-by-Side Comparison
| Digital Printing | Gravure Printing | |
|---|---|---|
| Setup cost | Very low (no cylinders) | Cylinder charge per color |
| Minimum order | Low — ideal for small batches | Higher — best for volume |
| Unit price | Higher, stays fairly flat | Drops significantly with quantity |
| Multiple SKUs / designs | Easy and affordable | Each design needs its own cylinders |
| Color consistency on reorders | Good | Excellent |
| Spot colors & metallic inks | Limited | Full support |
| Lead time | Shorter | Longer for first order (cylinder making) |
| Best for | Startups, market tests, seasonal or multi-SKU runs | Established products with steady demand |
Which One Should You Choose?
Choose digital printing if:
- You are launching a new product and want to test the market first.
- You need many designs in small quantities — for example, 8 coffee origins at 500 bags each.
- Your artwork changes often (seasonal editions, promotions, limited releases).
- You need bags quickly and want to avoid tooling costs.
Choose gravure printing if:
- Your product sells steadily and you order the same design again and again.
- You need thousands of bags per design and want the lowest unit price.
- Your brand relies on exact Pantone colors, metallic effects or large solid color areas.
- Color matching between reorders is critical for shelf consistency.
A Common Strategy: Start Digital, Scale to Gravure
Many brands use both. They launch with digital printing to keep upfront costs low and to prove the product in the market. Once sales are stable and order volumes grow, they switch the best-selling designs to gravure to cut the cost per bag — while keeping digital for new or slow-moving SKUs.
This approach lowers risk at the start and saves money as your business grows. If you sell coffee, see our coffee bags with degassing valve; if you are still choosing a bag format, read Stand-up Pouch vs. Flat-Bottom Bag.
Tips Before You Request a Quote
- Know your quantity per design, not just the total. 10,000 bags in one design and 10,000 bags across ten designs lead to very different recommendations.
- Count your colors. For gravure, the number of colors affects the cylinder cost.
- Share your artwork early. A packaging engineer can suggest small changes that reduce colors or improve printability.
- Ask about cylinder storage. For gravure orders, confirm that cylinders are kept for your reorders.
- Request a printed sample or proof before mass production, especially for brand-critical colors.
