Due to the original condition of some handwritten recipes, they may need additional editing. It may be because of very faint pen/pencil lines, stains on the paper, wrinkles or tears in the paper, the color of the paper (causing very little contrast between color of paper and pen/pencil), etc.
I do my very best to digitally prep your submitted recipe for the laser to read and engrave properly without these extra edits, but sometimes it's unavoidable. I then take the extra steps to hand trace every single pen stroke, line by line, so that only the handwriting (not the stains, paper wrinkles, etc.) is engraved into the wood. The tracing by hand, stroke by stroke, to make it look exactly like the original is time consuming, so this is for that extra time & editing.
