1. Understanding the Technologies
B2B custom packaging requires balancing design resolution, print accuracy, and production costs. The two dominant print technologies for custom folding cartons and corrugated shipping boxes are Offset Lithography and Industrial Digital Printing.
2. Crossover Volume Calculation
Offset printing relies on aluminum plates transfering ink onto rubber cylinders before applying it onto the paperboard sheet. This setup requires significant time, ink balancing, and plate fees. Digital printing, on the other hand, fires ink directly from nozzles onto substrates, requiring zero setup cost. However, the price per unit in digital is constant, whereas offset drops significantly as run length increases.
Crossover Rule of Thumb: For orders below 500 units, digital printing is highly cost-efficient. For orders exceeding 1,000 units, Offset Lithography offers massive savings per unit, superior gradient transitions, and precise spot Pantone color matching.
3. Technical Features Breakdown
| Feature | Offset Printing (Litho) | Digital Printing (Inkjet/Toner) |
|---|---|---|
| Plate Setup Cost | High (per color plate required) | Zero Setup Cost |
| Spot Pantone Matching | Perfect (precise physical mixing of spot inks) | Simulated (CMYK mix approximation) |
| Material Versatility | Wide (runs on corrugated, rigid card, metallic) | Limited (requires specific flat substrates) |
