What is Ulano Screen Printing Emulsion?

Ulano Screen Printing Emulsion is a photosensitive substance used to create stencils for screen printing. It acts as a barrier on the screen, allowing ink to pass through only where the stencil has been created. This emulsion is typically applied to the screen, exposed to light with a design or image, and then developed to reveal the stencil. Ulano Emulsion is known for its consistency, ease of use, and ability to produce high-quality prints.

Choosing the Right Ulano Emulsion for Your Needs

Selecting the appropriate Ulano Emulsion depends on factors such as the printing substrate, desired image resolution, ink type, and production requirements. Consider the specific characteristics of each emulsion variant, including the newly introduced Ulano Orange Emulsion, and match them with your printing needs for optimal results. Consulting with Ulano Emulsion experts or referring to the product specifications can also assist in making the right choice.

Preparing and Applying Ulano Emulsion

  1. Coating the Screen: Begin by ensuring the screen is clean and free from debris. Apply the emulsion evenly on the printing side of the screen, using a scoop coater or similar tool. Be mindful of coating thickness and avoid over-application to prevent excess buildup.
  2. Drying and Exposure: Allow the coated screen to dry in a controlled environment, ensuring proper ventilation and avoiding dust or contaminants. Once dry, place the artwork or design transparency on top of the screen and expose it to UV light or the recommended light source for the specified duration.
  3. Developing the Image: After exposure, carefully rinse the screen with water or a dedicated emulsion remover, using a gentle spray or showering technique. This step reveals the stencil by removing the emulsion in areas that were exposed to light, while the unexposed areas remain intact.

Troubleshooting Tips

  1. Overexposure: If the emulsion becomes difficult to wash out or the stencil details are not well defined, it may indicate overexposure. Adjust the exposure time or distance between the light source and screen to achieve the desired results.
  2. Underexposure: Insufficient exposure can result in emulsion washout in areas where it should remain, leading to blurred or incomplete stencils. Increase the exposure time or bring the light source closer to the screen to ensure proper hardening of the emulsion.
  3. Emulsion Peeling Off: If the emulsion begins to peel off the screen during printing, it could be due to improper coating or inadequate drying. Ensure a consistent and even coating thickness, and allow sufficient drying time before exposing the screen.
  4. Uneven Coating: Uneven coating may cause uneven ink deposition and affect the print quality. Use a scoop coater or similar tool to ensure a smooth and uniform application of the emulsion across the entire screen surface.

Maintenance and Storage

Proper maintenance and storage of Ulano Emulsion can prolong its shelf life and ensure optimal performance. Store the emulsion in a cool and dry environment, away from direct sunlight. Avoid exposing it to extreme temperatures or excessive humidity. Additionally, regularly clean and reclaim screens after printing to remove any residual emulsion and prevent buildup.
