This is an experimental design for reusable screenprinting screens. The basic idea is that a scoop coater is used to cover stainless steel screen with acrylic paint, which is used as a resist. A laser engraver is then used to remove the resist where necessary. After printing, the scoop coater is again used to fill the areas where resist was removed.

Bill of Materials:

Safe Operating Procedure:

Before using:

Ensure that the screen has been properly coated and dried.
Check that there is no tearing of the screen near the edges.
Engrave your image onto the screen using [100% speed, 100% power] with a PLS6.75 laser engraver.
Images should be rasterized to 1/2 the density of the screen material; if using a 120 mesh screen, rasterize the image to 60dpi. If using the 300 mesh, rasterize to 150 dpi. Note: 120 mesh is recommended for fabric screen printing.

While using:

Print quickly, to prevent ink from drying in the screen.
Pre-coat the screen with ink, before laying it on the substrate material.

After using:

Wipe excess ink from inside of screen.
Wash remaining paint in appropriate sink.
Hang to dry, and let managers know that the screen is ready to be recoated.

-Screenprinting, also known as silk screening, is a popular printing technique that involves creating images by applying ink through a mesh screen. Originally developed for textile printing, it has evolved to include a diverse range of applications, including graphic t-shirts, posters, and art prints. This method is favored for its versatility and the vibrant colors it can produce, making it a staple in both commercial and artistic settings.

-== Tutorial ==
+=== Safe Operating Procedure: ===
-=== Materials Needed ===
+==== Before using: ====
-* Screen (mesh fabric stretched over a frame)
-* Squeegee
-* Ink (textile or specialty inks)
-* Emulsion (light-sensitive liquid)
-* Transparency film (for your design)
-* Light source (for exposing the screen)
-* Substrate (t-shirt, poster, etc.)
-* Tape
-* Bucket of water (for cleanup)
-=== Steps ===
+* Ensure that the screen has been properly coated and dried.
-. **Create Your Design**: Use graphic design software to create your image. Print your design onto transparency film.
+* Check that there is no tearing of the screen near the edges.
+* Engrave your image onto the screen using [100% speed, 100% power] with a [[Universal PLS6.75|PLS6.75 laser engraver]].
-. **Prepare the Screen**: Apply emulsion evenly on both sides of the screen and let it dry in a dark room.
+* Images should be rasterized to 1/2 the density of the screen material; if using a 120 mesh screen, rasterize the image to 60dpi. If using the 300 mesh, rasterize to 150 dpi. Note: 120 mesh is recommended for fabric screen printing.
-. **Expose the Screen**: Place your transparency on the screen and expose it to a light source according to the emulsion's specifications. This process will harden the emulsion that is not covered by the design.
-. **Wash Out the Screen**: After exposure, rinse the screen with water. The areas that were covered by your design will wash out, leaving a stencil.
+==== While using: ====
-. **Set Up for Printing**: Secure the screen on a flat surface. Position your substrate where the ink will be applied.
+* Print quickly, to prevent ink from drying in the screen.
+* Pre-coat the screen with ink, before laying it on the substrate material.
-. **Apply Ink**: Pour ink at the top of the screen, and use the squeegee to pull the ink across the design, pressing down firmly to push ink through the mesh.
+==== After using: ====
-. **Lift the Screen**: Carefully lift the screen to reveal the printed design on the substrate.
+* Wipe excess ink from inside of screen.
+* Wash remaining paint in appropriate sink.
-. **Cure the Ink**: Let the printed material dry or cure the ink using a heat source based on the ink type used.
+* Hang to dry, and let managers know that the screen is ready to be recoated.

-. **Clean Up**: Wash the screen, squeegee, and any other tools immediately after use to prevent ink from drying and clogging the mesh.
