Choosing the right ink for your printing projects can make or break the final product. With options like plastisol, water-based, discharge, UV-curable, and 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.

Τι είναι το μελάνι Plastisol;

Μελάνι Plastisol is a go-to choice for screen printers worldwide. Made from PVC resin και 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 Ink
• International Coatings

Example: 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.
• Eco-Friendly: 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.

Best For: Baby clothes, eco-conscious brands, or light-colored apparel.

Example: 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.

Best For: Vintage-style shirts or brands like Bella+Canvas.

Example: 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.

Best For: Industrial printing, labels, or outdoor gear.

Example: 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.

Best For: Sportswear, leggings, or high-performance apparel.

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