Editing Pad printing (section)

===Disadvantages===
==== Wear ====
Pad printing is less durable than most other key-inscribing methods. Because the ink doesn't penetrate the key and become part of it, pad-printed legends can be worn away by abrasion. 

On some keyboards, only the legends on a few most-used keys may become worn. Other keyboards may end up with more legends missing than present, or with no significant wear at all. This depends on:

* How much the keyboard is used
* The hardness and thickness of the ink and protective coating (if present)
* The quality of the ink's adhesion to the key material, and of any coating to the ink
* The user's typing habits (lighter/stronger touch; amount of friction when pressing; tendency to rest hands on keys when not typing) 
* The user's skin chemistry (more acidic skin can accelerate wear)
* The cleanliness of the user's hands

Since dust and dirt are abrasive, most users can avoid unnecessary wear on pad-printed legends by washing their hands before they begin typing.

==== Tactility ====
Some pad-printing is thick enough to be felt. (The legends on [[Filco Majestouch]] keyboards can be felt through the coating that covers their keys.) Some users find this uncomfortable.
