Factors to Consider When Choosing Screen Printing Inks
Fabric Compatibility
Always check whether the selected ink is compatible with the fabric you are using. Different fabrics react differently to various inks. Here’s a brief list of common fabrics and their suitable inks:
- Cotton: Works well with plastisol, water-based, and discharge inks.
- Polyester: Preferably use plastisol or specially formulated inks for synthetic fabrics.
- Blend Fabrics: Both plastisol and water-based inks can work depending on the blend percentage.
Durability and Wash Resistance
Durability is crucial, especially if you expect the printed fabric to undergo frequent washing. Plastisol inks generally offer superior wash resistance compared to water-based options.
Color Vibrancy
If color vibrancy and opacity are essential for your project, plastisol inks tend to outperform water-based inks. However, if you’re going for a softer print, water-based inks could be the right choice.
Environmental Considerations
If sustainability is a priority, opt for water-based inks, as they contain fewer harmful solvents and are easier to clean up.
Common Problems and Practical Solutions
Problem: Ink bleeding or spreading
- Solution: Ensure proper emulsion development for your screens, choose the right mesh count, and adjust your squeegee pressure.
Problem: Inks not adhering to fabric
- Solution: Test your fabric for compatibility with your chosen screen printing ink for fabric. Pre-treat your fabric if necessary, and ensure proper curing temperatures are achieved.
Problem: Colors appearing dull after curing
- Solution: Validate the opacity of the inks before printing and consider using a white base layer to enhance color vibrancy.
Tips for Selecting the Right Screen Printing Ink
