Understanding how screen printing works and file types for best results
What is Screen Printing?
Screen printing is a printing technique where ink is pushed through a mesh screen onto a surface such as fabric, paper, or plastic. Each color in a design requires its own screen, making it ideal for bold, vibrant designs and bulk production.
The Screen Printing Process
1. Design Creation
The artwork is prepared digitally and separated by colors. Each color will be printed using a separate screen.
2. Screen Preparation
A mesh screen is coated with a light-sensitive emulsion. Once dried, the design is transferred onto the screen using UV light.
3. Exposure
The design blocks light during exposure, leaving open areas where ink will pass through after the emulsion is washed out.
4. Setup
Screens are aligned on a printing press. Each screen corresponds to one color in the design.
5. Printing
Ink is pushed through the screen using a squeegee onto the material. This is repeated for each color layer.
6. Curing
The printed item is heated to cure the ink, ensuring durability and wash resistance.
Raster vs Vector Files
Raster Files
Raster images are made of pixels. Common formats include JPG, PNG, and PSD.
- Resolution dependent
- Can become blurry when scaled
- Best for detailed images and photos
- Requires high resolution (300 DPI recommended)
Vector Files
Vector graphics are made using mathematical paths. Common formats include AI, EPS, and SVG.
- Resolution independent
- Scalable without losing quality
- Best for logos and solid color artwork
- Preferred format for screen printing
Why File Type Matters
Using the correct file type ensures clean prints and efficient production. Vector files provide crisp edges and accurate color separations, while raster files must be high resolution to avoid pixelation. For best results in screen printing, vector artwork is always recommended.
