Screen printing, also known as silkscreen printing, is a versatile and widely used printing technique that involves transferring ink onto a substrate (such as fabric, paper, or other surfaces) through a mesh screen. This process allows for the creation of vibrant, detailed designs and is commonly used for printing textiles, posters, and promotional materials. Screen printing is favored by artists and businesses alike for its ability to produce high-quality prints in bulk, as well as for its adaptability to various materials and surfaces.

== Tutorial ==
=== Safe Operating Procedure: ===
=== Materials Needed ===
* Screen printing frame (with mesh)
* Emulsion (photo emulsion or a pre-coated screen)
* Exposure unit or sunlight
* Ink (fabric ink or suitable for the chosen substrate)
* Squeegee
* Substrate (t-shirts, bags, paper, etc.)
* Tape (for sealing edges)
* Water source (for cleaning)
* A design (printed on a transparency film)


=== Steps to Screen Printing ===
==== Before using: ====
1. **Prepare Your Design**: Create your design using graphic design software. Print it on a transparency film. Ensure the design is opaque, as it needs to block light during exposure.


2. **Coat the Screen with Emulsion**: In a dark room, apply a thin, even layer of emulsion on the screen using a squeegee. Allow it to dry completely in a dark place.
* 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 [[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**: Place your dried screen in an exposure unit or under bright sunlight. Lay the transparency film with your design on top of the screen. Expose it for the recommended time (usually 5-15 minutes, depending on the emulsion and light source).
==== While using: ====


4. **Wash Out the Screen**: After exposure, rinse the screen with water. The areas that were blocked by your design will wash away, leaving a negative image.
* Print quickly, to prevent ink from drying in the screen.
* Pre-coat the screen with ink, before laying it on the substrate material.  


5. **Set Up for Printing**: Secure your substrate on a flat surface. Place the screen on top, aligning it properly. Use tape to seal the edges if necessary to avoid ink bleeding.
==== After using: ====


6. **Print**: Pour a line of ink at the top of the screen. Using a squeegee, pull the ink across the screen, applying even pressure. Lift the screen to reveal your printed design.
* Wipe excess ink from inside of screen.
 
* Wash remaining paint in appropriate sink.  
7. **Cure the Ink**: Depending on the type of ink used, you may need to cure it by heat setting or allowing it to air dry. Follow the manufacturer's instructions for curing time and temperature.
* Hang to dry, and let managers know that the screen is ready to be recoated.

8. **Clean Up**: Immediately clean your screen, squeegee, and any other tools used with water or the appropriate cleaning solvent to prevent the ink from drying on them.

[[Category:Textiles]]
=== Tips for Success ===
* Experiment with different types of inks and substrates to find the best combination for your needs.
* Practice your squeegee technique to achieve even pressure and avoid ink pooling.
* Always work in a well-ventilated area and wear gloves when handling chemicals and inks.

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.
