Printing systems or printers print images (e.g., a picture, a document, etc.) onto a substrate or a plurality of substrates (e.g., paper, cardboard, card stock, plastic, etc.). Printing systems therefore can convert digital information into physical images. Perturbations are unwanted errors (drop size, drop volume, line errors, misalignment, etc.) on images printed by a printing system.
