See our technical papers on silkscreening

Silkscreening, also known as screen-printing or serigraphy, is a printing technique that involves passing ink through a porous fabric, thus creating a sharp-edged single-color image created from a stencil.

For completing your fully finished, professional enclosure, you have two options for applying graphics for labelling, branding and decoration: direct digital printing and silkscreening. Each process offers its own benefits and advantages.

Our silkscreening process utilizes the latest in screen-preparation technology, as well as durable epoxy based inks, to ensure a high resolution and quality finish. Protocase stocks a variety of standard silkscreen ink colors, and can provide custom colors upon request.

You may silkscreen graphics onto enclosures, parts and panels that either have bare-metal finish or powdercoat finish.

The clarity of silkscreen can be greatly affected by the texture of powdercoat used. Generally, for best results, it is recommended you choose a smooth powdercoat finish. Silkscreen will work on various textures and colors but each situation is unique. This may require modifications to your silkscreen such as changing of fonts and thickening of fine lines. For more information, please contact tech support at

Font Sizes:

Minimum 9 pt font size required, with the exception of silkscreening over sandtex powdercoat, which requires a minimum 11 pt font size.

Acceptable Graphic File Formats:

  • .AI - Adobe Illustrator
  • .EPS - Encapsulated PostScript
  • .SVG - Scalable Vector Graphics
  • .PDF - Portable Document Format
  • .DXF or .DWG - AutoCAD

You can also include Graphics on your SolidWorks Models.

Please note: Saving a Raster image as any of the vector file formats will not create a vector graphic. You may need to contact the individual who created the graphic, in order to access the necessary files.
Raster (Non-Vector) (additional charges may apply)
  • .PNG - Portable Network Graphic
  • .JPG (.JPEG) - Joint Photographic Experts Group
  • .TIF (.TIFF)- Tagged Image File
  • .PSD - Photoshop

Image files must be provided electronically. Faxed images will not provide sharp enough resolution for our process to replicate. If text-only screening is required, simply provide information such as font type, font size and font color when you submit your order. Our graphics team will be happy to produce the required text-only screens.

As with everything in the manufacturing process, there are always some variance between parts and images (spatial registration). We use an X,Y and angular micro-adjust, which allows for a respectable tolerance of 0.020" | 0.51mm, which is more than adequate for most applications.

However, there are certain situations that are much more sensitive to disparation. Please see diagrams below for examples.

Figure 1 - Eccentric Circles: Left 0.020" (0.50mm) eccentricity x & y, middle 0.002" (0.05mm) x & y Right 0.010" (0.25mm) eccentricity x & y
