Welcome! This guide explores how inchiostri speciali enhance textile printing with expert insights from Industry Experience Ltd.
Whether you’re a beginner or a seasoned printer, we’ll break down the latest in stampa serigrafica, eco-friendly solutions, and advanced techniques.
Sommario
1. Tipi di inchiostri speciali
Specialty inks go beyond standard options, offering unique textures, finishes, and durability. Key categories include:
A. Plastisol Inks
- Durable & vibrant, ideal for apparel.
- Examples:
- Extra Green Plastisol Ink (ecologico)
- Extra Black Plastisol Ink (high opacity)
- Inchiostro Puff Plastisol (3D texture)
B. Water-Based Inks
- Sensazione morbida, eco-friendly.
- Lower VOC emissions, great for detailed designs.
C. UV-Curable Inks
- Fast-drying, works on rigid substrates (glass, metal).
- Energy-efficient with LED curing.
D. Special Effects Inks
- Finiture metalliche: Shimmering results.
- Glow-in-the-Dark: Perfect for novelty items.
- Inchiostri per sublimazione: Vibrant, dye-based prints.
Quick Comparison Table
| Tipo di inchiostro | Il migliore per | Key Benefit |
|---|---|---|
| Plastisol | Apparel, durability | High opacity, long-lasting |
| A base d'acqua | Progetti eco-compatibili | Soft hand feel |
| Polimerizzante UV | Hard surfaces | Instant curing |
| Puff/High-Density | Textured designs | 3D effect |
2. Screen Printing Techniques
Master these methods for flawless prints:
A. Setup
- Selezione del conteggio delle maglie: Higher for fine details (~230 mesh), lower for bold prints (~110 mesh).
- Screen Emulsion: Utilizzo Emulsioni Saati o Solventi per emulsione Ulano for clean screens.
B. Printing Process
- Pressione del tergipavimento: Adjust for even ink deposit.
- Polimerizzazione flash: Partially dry layers before adding colors.
- Precisione della registrazione: Align multi-color designs precisely.
C. Troubleshooting
- Clogged Screens? Utilizzo Ripristino dello schermo tecniche.
- Ink Not Sticking? Apply Adesivi per platine o Trattamento al plasma.
3. Sustainability in Screen Printing
Eco-friendly practices are revolutionizing the industry:
- Water-Based & Low-VOC Inks: Reduce harmful emissions.
- Polimerizzazione UV a LED: 50% less energy than traditional systems.
- Riduzione dei rifiuti: CTS systems cut ink waste by 50%.
Did You Know?
- 42% of printers now use water-based inks (2022 data).
- UV inks cure 3x faster than plastisol (2-5 sec vs. 60-90 sec).
4. Screen Printing vs. DTG: Which to Choose?
| Fattore | Serigrafia | Direttamente su capo (DTG) |
|---|---|---|
| Il migliore per | Bulk orders, special effects | Small batches, photo prints |
| Efficienza dei costi | Lower per unit at scale | Higher for small runs |
| Ink Options | Plastisol, puff, metallic | Water-based CMYK |
Hybrid Tip: Combine both for cost-effective, high-quality mixed runs.
5. Future Trends
- Inchiostri intelligenti: Thermochromic (heat-sensitive) and photochromic (light-reactive).
- Automation: Sfidante III di M&R presses boost speed.
- Inchiostri conduttivi: For wearable tech and IoT devices.
Punti chiave
- Match ink type to project needs (e.g., plastisol for durability, water-based for softness).
- Prioritize sustainability with LED curing and waste-reducing tech.
- Flussi di lavoro ibridi optimize cost and quality.
