Keys that are curved on all four edges (see from the photo to the left). A spherical well is in the
center of each key. These keys are typically found on old model typewriters like the IBM

Key Printing
There are a variety of printing types from pad printing to dye sublimation printing. If you are not
familiar with these terms, it can be quite confusing as to whether you need a keyboard with pad
printing or if it’s worth spending the money for double-shot injection molded keys.
Pad Printing (or Screen Printing)
The least expensive, most common form of key printing is Pad Printing, where the key image is
printed using a durable ink. Often, the manufacturer will follow up with a clear coat to extend the
life of the image. Unfortunately, this type of printing tends to wear out fast for most heavy
typists. Check out the video to see how the production process works.
