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 silkscreen printing or serigraphy, is a versatile and widely used printing technique that involves creating a stencil (or screen) and using it to apply layers of ink on a printing surface. This method can be used on various materials, including textiles, paper, glass, and plastics. Screenprinting is popular in both commercial and artistic contexts due to its ability to produce vibrant, long-lasting colors and intricate designs.

-== Tutorial ==
+=== Safe Operating Procedure: ===
-=== Materials Needed ===
-* Screen (usually a mesh stretched over a frame)
-* Squeegee
-* Screen printing ink
-* Emulsion and sensitizer
-* Transparency film
-* Light source for exposing the screen
-* Printing surface (e.g., t-shirt, paper, etc.)
-* Tape
-* Gloves and apron (optional, for protection)
-=== Step-by-Step Guide ===
+==== Before using: ====
-==== 1. Prepare Your Design ====
-Create your design on a computer or draw it by hand. Once you have your design, print it onto a transparency film. This will be used to transfer your design onto the screen.
-==== 2. Coat the Screen with Emulsion ====
+* Ensure that the screen has been properly coated and dried.
-Mix the emulsion and sensitizer according to the instructions. In a dark room, coat the screen evenly with the emulsion using a squeegee. Let the screen dry in a dark place.
+* 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]].
+* 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.
-==== 3. Expose the Screen ====
+==== While using: ====
-Place your transparency film with the design on the screen and expose it to a light source. Follow the emulsion manufacturer’s instructions for exposure time. The light will harden the emulsion, except where your design blocks the light.
-==== 4. Rinse the Screen ====
+* Print quickly, to prevent ink from drying in the screen.
-After exposure, rinse the screen with water. The areas of emulsion that were not exposed to light will wash away, leaving your design on the screen.
+* Pre-coat the screen with ink, before laying it on the substrate material.
-==== 5. Set Up Your Printing Area ====
+==== After using: ====
-Place the screen on your printing surface. Make sure it is aligned correctly. Tape off the edges of the screen to prevent ink from leaking through.
-==== 6. Apply the Ink ====
+* Wipe excess ink from inside of screen.
-Pour a small amount of ink at the top of the screen. Use the squeegee to pull the ink across the screen, pressing firmly to push the ink through the mesh and onto the printing surface.
+* Wash remaining paint in appropriate sink.
+* Hang to dry, and let managers know that the screen is ready to be recoated.
-==== 7. Lift the Screen ====
+[[Category:Printmaking]]
-Carefully lift the screen to reveal your printed design. Allow the ink to dry completely.

-==== 8. Cure the Ink ====
-Depending on the type of ink you used, you may need to heat-set the ink to make it permanent. Follow the ink manufacturer's instructions for curing.
