Bold, open, sans serif fonts work best for deep etching, and if at all possible, avoid small script fonts. We recommend text being 8 points or larger, but it all depends on the font your customers are choosing. The larger the font, the clearer the text will be. We’ve also found that positive artwork should be a minimum of .75 points thick in order to etch well, while negative artwork should be a minimum of 1.5 points thick. Sharp points should also be blunted, rounded, or thickened.
