What is a coating trough? Definition and significance in screen printing
A coating trough is a key tool in screen printing, used to apply light-sensitive emulsion evenly to the screen fabric. It ensures that the emulsion layer is applied precisely, cleanly, and evenly—a basic requirement for razor-sharp printing results. Different squeegee widths and shapes can be used depending on the motif, printing requirements, and fabric type.
Arsonists, your creative partner for customized, high-quality textile finishing in Munich, works with professional coating troughs to give every project a solid foundation right from the start. After all, the quality of the coating has a decisive influence on how precise and durable the final print screen will be.
Why is the coating trough indispensable in screen printing?
The coating trough plays a key role in print preparation:
- Precise layer thickness: This ensures that the emulsion is distributed evenly – crucial for flawless exposure.
- Quality improvement: A clean and even coating prevents defects such as bubbles, streaks, or uneven color transparency.
- Efficiency: With the right gutter, you can prepare sieves faster and more consistently.
At Arsonists, we focus on maximum precision so that even the preparation of the screens reflects our customers' quality standards.

The use of a coating trough involves several steps:
- Preparation: Clean and degrease the sieve.
