Abstract
Systems and methods of marking ladders.

Claims18
A method for marking a ladder comprising contacting a ladder portion with an image reverse printed on a paper sheet with at least one sublimation ink, and applying heat to the paper sheet such that at least a portion of the ink sublimates from the paper sheet into the ladder portion.
A method of safeguarding a ladder comprising contacting a ladder portion with an image reverse printed on a paper sheet with at least one sublimation ink, and applying heat to the paper sheet such that at least a portion of the ink sublimates from the paper sheet into the ladder portion to provide the ladder portion with an image that allows the ladder to be readily identified.
A system for marking a ladder comprising a printer for reverse printing an image onto a paper sheet with at least one sublimation ink, and a heat press adapted to hold a portion of the ladder in contact with the reverse-printed image while applying heat to the paper sheet, the heat causing at least a portion of the ink to sublimate from the paper sheet into the ladder portion.
