[Черномашенцев Владимир]

I think that now the word etching is often referred to all such printed products, including offset printing.
I often met: "License plate etching, signed by the artist so and so."
And there has been offset with watercolors.

This is a mistake, or you can, and so to speak? After all, words often change over time its meaning. Or words change meaning, migrating to another country.
