Types of Custom Formula Screen Printing Ink

When it comes to custom formula screen printing ink, several types are available, each suited for different applications and materials. Understanding these options can make a big difference in your print quality.

1. Water-Based Screen Printing Ink

   • Advantages: Environmentally friendly, soft to the touch, and excellent for fabric applications.
   • Ideal For: Cotton and other natural fibers, where breathability and softness are top priorities.

2. Plastisol Ink

   • Benefits: Great for vibrant colors and high opacity; it doesn’t dry on the screen.
   • Use Cases: Suitable for all fabric types, particularly useful for dark garments.

3. Discharge Ink

   • Pros: Removes dye from the fabric, leaving a soft print with no hand feel.
   • Applications: Best for light-colored garments, especially those made of 100% cotton.

4. Specialty Inks

   • Examples: Metallic, glow-in-the-dark, and puff inks that offer unique effects.
   • Considerations: These inks often require specific techniques and can add to production time.

1. Fabric Compatibility

• Natural vs. Synthetic: Ensure that the ink you choose is compatible with the fabric type. Water-based inks are typically recommended for natural fibers, while plastisol works great on a mix of materials.
• Testing: Always test your ink on a sample fabric before committing to a large batch.

2. Colorfastness and Washability

• Durability: Custom formula screen printing ink must withstand washing and fading. Look for inks that offer high colorfastness.
• Testing for Washability: Perform wash tests to ensure the colors hold up after several cycles.

Choosing the Right Dyestuffs

Dyestuffs play a significant role in the color and quality of screen printing inks. They affect how well the ink adheres to the fabric and how vibrant the colors appear.

• Type of Dye: Opt for dyes specifically designed for the type of ink you're using. For example, use reactive dyes for water-based inks to achieve optimal results.
• Shade Matching: Consider using a color matching system to ensure you get the precise shade you need.

Common Problems and Solutions

Problem 1: Ink Drying Too Quickly

Solution:

• Adjust your printing environment, controlling humidity and temperature.
• Use a slower-drying ink formula or add retarders.

Problem 2: Inconsistent Color Quality

Solution:

• Ensure thorough mixing of inks before use.
• Regularly clean screens and squeegees to prevent contamination.

Problem 3: Poor Adhesion to Fabric

Solution:

• Use pre-treatment processes like heat-setting or using adhesion-promoting additives.
• Test different ink formulations designed for the specific fabric type.

Practical Suggestions for Selection

1. Sample Testing: Always request samples from suppliers to test different options before settling on a custom formula.
2. Consult Experts: Don’t hesitate to reach out to manufacturers or experienced printers for advice tailored to your specific needs.
3. Consider Your Process: Think about your printing method—manual versus automatic—as this can influence the type of ink that works best.
