Introduction
The choice of printing technique on bags has a direct impact on the visual effect, cost and delivery time. Two methods are most commonly used: screen printing (Pantone colors, excellent colors) and digital printing (full color, photos, no prepress costs). Below we compare them "humanly" to easily choose the best option for your order.
What is screen printing
- Each color is a separate matrix (frame with mesh and emulsion).
- Printing with opaque inks (e.g. Pantone) – great coverage and repeatability.
- Best for flat designs, logos, simple shapes, 1-3 colors.
- Requires a preparation room (matrices) – it pays off at higher costs.
What is digital printing
- Matrix-free printing – no prepress costs.
- Full color (CMYK), great for photos, gradients, small details.
- Perfect for low volumes and many variants (personalization).
- Metallic/specialties require separate techniques (e.g. hot-stamping).
Quality and aesthetics – comparison
- Color Accuracy (Pantone): screen printing wins because it prints with colors from the Pantone mixer; digital is CMYK (Pantone simulation).
- Large fields and flat fields: screen printing produces even, highly opaque surfaces.
- Photos, gradients, illustrations: digital better (high resolution, smooth transitions).
- Small text / micro detail: digital usually more readable in small and semitones; screen printing is great for simple shapes.
- Special effects: metallic, pearly, puffy – this is the domain of screen printing and/or hot-stamping.
Durability, opacity and paper
- Opacity on dark bags: screen printing with a white underprint gives a very strong effect; digital may be less opaque (depending on the device and foundation).
- Mechanical resistance of the print: both are durable with the right choice of paints; screen printing usually creates a slightly "thicker" layer.
- Paper type kraft brown → screen printing (strong colors, contrast); dyed/laminated papers → both techniques, the decision depends on the project.
Costs and profitability
Screen printing: prepress cost (matrices) + printing cost (depending on the number of colors and print area). The larger the quantity and the fewer colors, the cheaper "per piece".
Digital: no preparation room; the price depends mainly on the printing area and quantity. Low to medium print runs and full color/gradients are preferred.
- Low circulation / multiple versions: digital usually wins.
- High print run / 1–2 colors / large areas: screen printing usually cheaper per piece.
- Multicolor Pantone logos: count each color; digital printing can be an alternative if 'perfect Pantone' is not critical.
Production deadlines and flexibility
- Digital: quick start (no plates), flexible for corrections and reprints.
- Screen printing: requires time for plates/tests; for large batches the 'actual printing' stage can sometimes be the fastest.
Ecology and materials
- Both methods can use environmentally friendly (water-based) paints; the real impact depends on the project (paint coverage, waste, transport).
- Remember to choose paper (recycling/FSC) and a reasonable format – these are the greatest ecological "levers".
Quick technique selection checklist
- Do you have a logo in 1-2 colors, large size, high circulation? → Screen printing.
- Do you want photos/gradients/large volumes or low print runs? → Digital printing.
- Need metallics/special effects? → Screen printing or hot-stamping.
- Crucial 1:1 Pantone matching? → Screen printing.
- Multiple languages/personalization? → Digital printing.
Comparison table
| Feature | Screen printing | Digital printing |
|---|---|---|
| Corporate colors (Pantone) | ✔ exact Pantone | ~ CMYK (simulation) |
| Photos/Gradients | ~ limited | ✔ perfect |
| Large shades, opacity on dark | ✔ very good (white underprint) | ~ depends on the device |
| Preparation cost | Yes (matrices) | None |
| Profitability | High runs / 1-2 colors | Low-medium print run / full color |
| Start dates | Slower start | Quick start |
| Special effects (metallic etc.) | ✔ (or hot-stamp) | ✖ (requires a different technique) |
Example scenarios
- Premium Shop, black bags, gold effect: screen printing with metallic paint or hot-stamping.
- Event 300 pcs, full color graphics: digital printing (quick start, no matrices).
- Standing orders 5,000+ pcs, 1 logo color: screen printing (low price/pcs).
- Multiple language versions of 100-200 pcs.: digital (savings on prepress).
FAQ
Will I get a perfect Pantone in digital?
No – it's a CMYK print. If Pantone compliance is key, choose screen printing.
Will the digital be clearly visible on brown kraft?
Depends on device and design. For strong coverage on dark paper, screen printing with a white underprint is the most reliable.
I want a metallic gold/silver effect.
Screen printing with metallic paint or hot-stamping (flash/shine and the highest premium effect).
Summary
Digital dial when it counts time, low/medium circulation, full color and flexibility. Screen printing will work best for high print runs, simple Pantone logos and strong coverage. If you are still hesitant, send us the design and quantity and we will advise you on the optimal technique and deadline.
