Choosing the right ink for your printing projects can make or break the final product. With options like plastisol, vandbaseret, udledning, UV-hærdende, og sublimation inks, it’s essential to understand their strengths, weaknesses, and best uses. This guide breaks down everything you need to know to make informed decisions.

Hvad er Plastisol Ink?

Plastisol-blæk is a go-to choice for screen printers worldwide. Made from PVC harpiks og liquid plasticizers, it’s known for its durability and vibrant colors. Here’s what sets it apart:

• Heat-Cured: Requires temperatures above 300°F to dry.
• Thick Consistency: Perfect for bold, opaque designs on dark fabrics like cotton.
• Long-Lasting: Survives 50+ washes without fading, making it ideal for workwear or sportswear.

Common Uses:

• T-shirts, hats, and tote bags.
• Sportswear and promotional items.

Top Brands:

• Wilflex
• Union blæk
• Internationale belægninger

Eksempel: Printers often use plastisol for company uniforms because the colors stay bright even after repeated washing.

How Plastisol Ink Compares to Other Inks

1. Plastisol vs. Water-Based Ink

Water-Based Ink Pros:

• Soft Feel: The ink soaks into the fabric, leaving no texture.
• Miljøvenlig: Contains 90% fewer harmful chemicals (VOCs) than plastisol.
• Great for Light Fabrics: Works well on light-colored cotton.

Water-Based Ink Cons:

• Long Drying Time: Requires heat presses or air drying.
• Fades on Dark Fabrics: Not ideal for bold designs on black shirts.

Bedst til: Baby clothes, eco-conscious brands, or light-colored apparel.

Eksempel: Outdoor brand Patagonia uses water-based inks to meet strict environmental standards like Oeko-Tex certification.

But using thermosetting ink to make dots has the best feel.

2. Plastisol vs. Discharge Ink

Discharge Ink Pros:

• Vintage Look: Removes dye from dark fabrics, creating a soft, worn-in appearance.
• Breathable Finish: Feels lighter than plastisol.

Discharge Ink Cons:

• Limited Fabric Compatibility: Only works on 100% cotton.
• Short Shelf Life: Lasts about 6 months before losing effectiveness.

Bedst til: Vintage-style shirts or brands like Bella+Canvas.

Eksempel: A small apparel brand switched to discharge ink for retro designs, attracting customers who love a “lived-in” look.

3. Plastisol vs. UV-Curable Ink

UV-Curable Ink Pros:

• Instant Drying: Cures in 1–5 seconds under UV light.
• Weatherproof: Resists sun, rain, and scratches, perfect for outdoor signage.

UV-Curable Ink Cons:

• High Cost: 30% more expensive than plastisol.
• Special Equipment Needed: Requires UV lamps and compatible printers.

Bedst til: Industrial printing, labels, or outdoor gear.

Eksempel: Avery Dennison uses UV ink for truck decals that withstand harsh weather conditions.

4. Plastisol vs. Sublimation Ink

Sublimation Ink Pros:

• No Cracking: Stretches with polyester fabrics, ideal for activewear.
• Full-Color Designs: Perfect for photorealistic prints.

Sublimation Ink Cons:

• Polyester Only: Doesn’t work on cotton.
• Special Paper Required: Adds to production costs.

Bedst til: Sportswear, leggings, or high-performance apparel.

Eksempel: Nike uses sublimation ink for its Dri-FIT line, ensuring designs stay intact during intense workouts.
