Screen wash is a cleaning chemical used in screen printing to remove ink residue from a screen after printing is finished. It dissolves and lifts ink from the mesh without damaging the screen, allowing the stencil to remain intact if the screen is being reused for the same design.
Screen wash is an essential part of screen maintenance and cleanup. It is commonly used between print runs, during color changes, or before the screen reclaiming process.
Key properties of screen wash
Screen wash is formulated to clean ink efficiently while protecting the screen mesh and stencil. Key properties include:
● Ability to dissolve fresh and partially cured inks
● Safe use on polyester mesh
● Compatibility with common screen printing inks
● Controlled evaporation rate
● Effective ink removal without stencil damage
These properties make screen wash suitable for daily screen cleaning.
How screen wash works in screen printing
Screen wash works by breaking down ink binders and pigments so they can be rinsed away from the mesh. The cleaning process typically includes:
● Applying screen wash to both sides of the screen
● Allowing the chemical to dissolve ink residue
● Scrubbing the mesh with a brush or pad
● Rinsing the screen thoroughly with water
● Inspecting the mesh for remaining ink
● Repeating the process if necessary
Proper use ensures clean mesh openings and consistent ink flow.
