Protocase Tech Tip Video

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.

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.

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

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.

Font Sizes:

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

Cleaning Your Enclosures & Parts

We recommend any part or enclosure with digital print or silkscreen be cleaned using a mild soap/degreaser (for example: dish detergent), or water with a soft (non-abrasive) cloth or sponge.

Avoid using isopropyl alcohol, lysol wipes, acetone or hand sanitizer. For cloths, we do not recommend paper towel, as it is abrasive.


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

Please note: Images are a scaled representation of a CAD drawing of half-inch circles around quarter inch holes

We strive for excellence with the goal of reducing Foreign Object Debris (FOD) and achieving consistency with all silkscreening. However, due to some constraints of our facility, there may be minor blemishes on parts. These blemishes are not distinguishable or seen from an arm’s length away.
