Understanding Spray Adhesive in Screen Printing

Spray adhesive is a crucial component in screen printing, often misunderstood by newcomers. The primary purpose of spray adhesive is to keep the fabric in place on the platen (or "dask") during printing. This ensures that the fabric does not shift, which could cause misalignment and blurring of the print.

How to Use Spray Adhesive

1. Prepare the Platen: Clean the platen to remove any dust or residue.
2. Apply the Adhesive: Spray a light, even coat of adhesive on the platen. Avoid over-spraying as too much adhesive can make the fabric stick too firmly and be difficult to remove.
3. Position the Fabric: Place the fabric smoothly on the platen, ensuring it is flat and free of wrinkles.
4. Proceed with Printing: With the fabric secured, proceed with the screen printing process.

Achieving High-Quality Prints

To achieve high-quality prints, it is essential to understand the nuances of screen printing techniques. One common issue is prints appearing too thick or "podgy." Here are some tips to improve your print quality:

Tips for Better Prints

1. Use the Right Mesh: Select the appropriate screen mesh for your design. Finer details require a higher mesh count.
2. Proper Ink Viscosity: Ensure the ink is at the right consistency. If it's too thick, it can lead to excessive build-up on the fabric.
3. Even Squeegee Pressure: Apply even pressure with the squeegee to push the ink through the screen evenly. Uneven pressure can cause streaks and inconsistent prints.
4. Curing the Ink: Properly cure the ink according to the manufacturer's instructions to ensure it adheres well to the fabric and lasts through washes.

Common Misunderstandings

In screen printing, some terms and processes can be confusing. For instance, a term like "tumidity printing" might not be familiar. It could refer to achieving a specific texture or quality in the print. It's essential to clarify such terms to ensure proper understanding and application of techniques.

Clarifying Misunderstood Terms

• Spray Adhesive: As previously mentioned, it helps in securing the fabric to the platen.
• Discharge Printing: This process involves using a discharge agent to bleach the dye in the fabric, allowing for a soft print. This might be mistaken for adhesive spray due to its preparation steps.
