1. A method for facilitating calibration of turn-on energy of a fluid-ejecting marking device, the method comprising the steps of: printing a reference object at a first energy level with the fluid-ejecting marking device, the reference object being printed on a substrate of a first type; printing a plurality of test objects at different energy levels with the fluid-ejecting marking device, the plurality of test objects being printed on one or more substrates of the first type; identifying one or more test objects of the plurality of test objects that resemble the reference object; identifying one or more identified energy levels or identified data related to one or more energy levels used to print the one or more selected test objects; calculating data pertaining to a turn-on energy for the fluid-ejecting marking device based at least upon the identified energy levels or identified data; and outputting the calculated data.
