When it comes to screen printing, the choice of ink can make or break your project. Among the various types of inks available, plastisol ink stands out due to its vibrant colors, durability, and ease of use. However, sometimes, blending inks can offer unique benefits and expand your creative horizons. One such blend is mixing poly and plastisol ink. But what is the correct ratio for mixing poly and plastisol ink? This article delves into the intricacies of this blend, offering insights into why and how you should mix these inks, the correct ratios, and the potential pitfalls to avoid.
Understanding the Basics: What Are Poly and Plastisol Inks?
Before diving into the mixing ratios, it’s crucial to understand the basics of both poly and plastisol inks.
প্লাস্টিসল কালি:
Plastisol ink is a suspension of pigment in a gelatinous plastic vehicle. It remains liquid until heated, where it flows into the fabric fibers and then solidifies upon cooling. This ink is known for its opacity, vibrancy, and durability.
Poly Ink:
Poly ink, or polyurethane ink, is a water-based ink that dries through evaporation. It’s flexible, stretchable, and often used for printing on fabrics that require a high degree of stretchability, such as athletic wear.
Why Mix Poly and Plastisol Ink?
Mixing poly and plastisol ink can offer a range of benefits, including:
- Enhanced Flexibility: Poly ink adds flexibility to the mix, making it suitable for printing on stretchable fabrics.
- Color Expansion: Combining inks can create unique hues that aren’t achievable with a single ink type.
- খরচ সাশ্রয়: In some cases, mixing inks can be more cost-effective than purchasing specialized inks.
The Correct Ratio for Mixing Poly and Plastisol Ink
Determining the correct ratio for mixing poly and plastisol ink isn’t a one-size-fits-all scenario. It depends on the desired outcome, the type of fabric, and the printing method. However, here are some general guidelines to get you started:
- Starting Point:
A common starting ratio is 1 part poly ink to 3 parts plastisol ink. This ratio provides a good balance of flexibility and durability. - Testing:
Always perform a test print before committing to a large-scale project. Adjust the ratio incrementally and test each iteration to find the optimal blend for your needs. - Considerations:
- কাপড়ের ধরণ: The stretchability and texture of the fabric will affect the ink’s performance.
- Printing Method: Different printing techniques may require different ink viscosities.
- Desired Outcome: Are you looking for a softer hand feel, enhanced durability, or a specific color?
Mixing Plastisol Ink for Screen Printing
Screen printing with plastisol ink is a popular choice due to its vibrant colors and durability. When mixing plastisol inks, consider the following tips:
- Consistency: Ensure all plastisol inks used in the mix have a similar consistency.
- রঙ মেলানো: Use a color matching system to blend plastisol inks accurately.
- স্টোরেজ: Mixed plastisol inks should be stored in a cool, dark place to prevent premature curing.

Adding foil adhesive to plastisol ink can create a metallic or reflective effect. Here’s how to do it:
- Ratio: Typically, you’ll use a small amount of foil adhesive, around 5-10%, mixed with plastisol ink.
- আবেদন: Apply the mixed ink using a standard screen printing process.
- আরোগ্যকরণ: Ensure the ink is fully cured to bond the foil adhesive properly.
Mixing Plastisol Inks: Best Practices
When mixing different shades of plastisol inks to create new colors, follow these best practices:
- Use a Scale: Accurately measure the weights of each ink to achieve consistent results.
- Clean Tools: Use clean mixing tools to avoid contamination.
- টেস্ট প্রিন্ট: Always create test prints to evaluate the color and coverage.

Teal is a popular color in screen printing, often used for sportswear and promotional materials. When mixing teal plastisol ink, consider these tips:
- Base Colors: Start with a blue and green base, adjusting the proportions to achieve the desired shade.
- সংযোজন: Use white or black ink to lighten or darken the teal, respectively.
- Mixing Technique: Use a slow, stirring motion to avoid incorporating air bubbles.
Addressing Common Mixing Challenges
Mixing poly and plastisol ink isn’t without its challenges. Here are some common issues and solutions:
- Separation: Mixed inks may separate over time. Stir well before use and consider adding a stabilizer.
- Curing Issues: Mixed inks may cure at different rates. Test prints will help identify any curing inconsistencies.
- Color Shift: Mixed colors may shift slightly upon curing. Create a color profile to account for this shift.
Real-World Examples and Case Studies
To illustrate the practical application of mixing poly and plastisol ink, let’s explore a few real-world examples:
- Athletic Wear: A sportswear manufacturer mixed poly and plastisol ink to create a durable, stretchable print that maintained its vibrancy after repeated washing.
- Promotional Materials: A printing company mixed teal plastisol inks to create custom t-shirts for a music festival, achieving a cohesive and eye-catching look.
- Fashion Accessories: A designer mixed poly and plastisol ink to print patterns on stretchy fabric bags, enhancing both the aesthetic and functionality.
Conclusion: The Art and Science of Mixing Poly and Plastisol Ink
Mixing poly and plastisol ink is both an art and a science. By understanding the basics of both ink types, testing different ratios, and considering the specific needs of your project, you can achieve unique and striking prints. Remember, the correct ratio isn’t a fixed number but a starting point for experimentation and discovery. Always perform test prints, monitor curing processes, and be prepared to adjust your technique to achieve the best results.
In summary, mixing poly and plastisol ink offers a versatile and creative approach to screen printing. With the right ratio, technique, and attention to detail, you can unlock a world of possibilities and elevate your printing projects to new heights.
