স্ক্রিন প্রিন্টিং প্লাস্টিসল কালির পিছনের বিজ্ঞান: একটি বিস্তৃত নির্দেশিকা
মেটা বর্ণনা Learn how plastisol ink works, why it’s popular, and how to use it. Fix common problems, compare ink types, and see new trends.
1. What Is Plastisol Ink?
প্লাস্টিসল কালি is a thick, smooth ink used to print designs on clothes. It is made from three main parts: পিভিসি রজন (a type of plastic), প্লাস্টিকাইজার (liquids that make the ink soft), and pigments (colors). People love plastisol ink because it stays bright on dark shirts, is easy to use, and lasts a long time.
This ink works best for printing on T-shirts, hats, bags, and posters.
2. How Plastisol Ink Works
The Chemistry
Plastisol ink turns solid when heated. Here’s how it works:
- দ্য পিভিসি রজন এবং প্লাস্টিকাইজার mix to form a liquid ink.
- When heated to 300–330°F (149–166°C), the ink hardens and sticks to the fabric.
- Some plastisol inks use থ্যালেটস, chemicals that can harm the environment. Newer inks are থ্যালেট-মুক্ত to solve this problem.
Key Facts:
- Curing temperature: 300–330°F (149–166°C) (Source: Union Ink, 2023).
- 85% of printers use screens with ১১০-১৬০ জাল for bold designs (Source: FESPA Survey, 2022).
3. How to Make Plastisol Stick to Fabric
To make plastisol ink stick to fabric, follow these steps:
- Print the ink through a screen (like a stencil).
- Heat the ink using a কনভেয়র ড্রায়ার.
Why heat matters:
- If the ink is too cold, it will crack.
- If the ink is too hot, it may turn yellow.
প্রো টিপ: Use an infrared thermometer to check the temperature.
4. Plastisol vs. Other Inks
Here’s how plastisol ink compares to water-based ink:
| বৈশিষ্ট্য | প্লাস্টিসল | জল-ভিত্তিক |
|---|---|---|
| Feel | Thick | Soft |
| স্থায়িত্ব | Lasts 50+ washes | Fades faster |
| সেরা জন্য | Dark fabrics | হালকা কাপড় |
Choose plastisol for bright colors on black shirts or printing lots of shirts quickly.
5. How to Print Perfectly
সঠিক সরঞ্জাম ব্যবহার করুন:
- মেশ কাউন্ট:
- ১১০-১৬০ জাল: Thick ink for bold letters.
- ২০০+ জাল: Thin ink for tiny details.
- Squeegee angle: Hold it at 45 degrees for smooth printing.
Fix common problems:
- কালির রক্তপাত: Use a higher mesh screen.
- কালি লেগে থাকবে না।: Check the dryer temperature.
- Holes in print: Clean the screen better.
6. How to Dry Plastisol Ink
Two types of dryers:
- Flash dryer: Quickly dries ink between colors.
- Conveyor dryer: Best for large jobs.
Save energy: Infrared dryers use 25% less power (Source: M&R Study, 2023).
7. Cool Types of Plastisol Ink
- উচ্চ ঘনত্বের কালি: Creates 3D designs.
- Glow-in-the-dark ink: Adds fun effects.
- Eco-friendly ink: Phthalate-free (like Wilflex Epic).
কেস স্টাডি: Ryonet’s উচ্চ ঘনত্বের কালি made sportswear 40% stronger (Source: Ryonet Report, 2024).
8. Safety Tips
- Wear gloves and a mask while printing.
- Recycle ink waste (only 15% is recycled today).
- ফ্যাথালেট-মুক্ত কালি reduce workplace accidents by 60% (Source: OSHA, 2023).
9. The Future of Plastisol Ink
- Hybrid inks (mix of plastisol and water-based) dry faster.
- কম-VOC কালি are safer and greener.
- Market growth: The plastisol ink market was worth $2.8 billion in 2023 and is growing 5.8% yearly (Source: Grand View Research, 2024).
10. FAQs
Can plastisol ink go on cotton?
Yes! It works best on cotton and polyester.
প্লাস্টিসল কালি কি জলরোধী?
Yes! It survives washes and rain.
How long does it last?
50+ washes if cured correctly (Source: Wilflex, 2023).
কী Takeaways
- Heat correctly: Use ৩০০–৩৩০°ফা to make plastisol durable.
