A customer asked if I could laser engrave six wooden chopping boards with her granny’s Highlander recipe as gifts for her family for Christmas. To make the gifts extra special, she had scanned her granny’s recipe from her old recipe book. She wondered if we could engrave the boards to look as if her granny had written the recipe on the boards herself.
My customer prepared the artwork herself and got it right first time.
Scanning handwriting for laser engraving
We need artwork for engraving in black and white with no greyscale. This is very important because the laser either engraves or doesn’t engrave. It engraves black and doesn’t engrave white. If the artwork is greyscale, the software interprets greys as being either dark enough to be black or pale enough to be white and engraves accordingly. The laser creates shades of grey in the way that old fashioned newsprint did, by engraving concentrations of black pixels. As the laser engraves each black pixel, black and white artwork works best.
It is also important that if artwork if presented in jpg, png or bitmap format (as my customer did), the graphics must be of print quality, in other words, 300dpi or greater. Unwanted pixellation will be engraved, so customers should provide good, clean unpixellated images for best results. Engraving is only as good as the artwork is.
Engraving the boards
The text was very fine, as you’d expect from handwriting. We performed some test engraves and got good results using a deep engrave to give the text good definition. My customer loved the engraved boards. Having a fresh reminder of her granny in her kitchen was special as she prepared to start her own family.
