Explanation of Image Resolution
( dpi = dots per inch )
Bitmap images are made up of a grid of square dots. Each dot can either be black or white.

So let's say for example you have a logo image file that is 72 dots tall...

Typical resolution of your computer screen is 72 dpi, so, viewed on screen it will be 1 inch tall and look pretty good.

Engraving resolution is 300 dpi, so that same image engraved will be about 1/4" inch tall.

Enlarging that same image to 1" tall for engraving will look rough and jaggy. Why? because the quantity of dots remain the same, they just get larger.


Quality Engraving (or printing on paper) requires 300 to 600 dpi resolution —at the size to be engraved.
