sorry for the misunderstanding. Keith does a great job, as he points out the main purpose of calibrating for him is because he is trying to insure his profiles work for others. I’m not quiet sure how this works, unless he re-calibrates frequently before making profiles on new paper to insure there hasn’t been any drift.
I cannot see where in the article it states it came with his printer. He just states what the Calibration software does and shows the icon for it. Keith obviously has it and this is part of his workflow, but i think he’s the exception. I don’t think the software is provided, most likely because Epson doesn’t see a real purpose for it anymore except for perhaps field technicians. These printers just don’t drift and machine to machine tolerance are very tight.
but i certainly understand your curiosity.
You’ve managed to get me a little curious as well
. For example, one question for those in the know who have used the software and happen to be reading this thread. In using the software to record it’s current state, then again to use the software to measure and correct any drift, what is the mechanism where the printer reads the results? Keith says he didn’t purchase the optional spectro, so I’m not sure how the printer is “measuring” it’s output to set it’s know state, then again measuring and modifying the output to achieve calibration. What exactly is it measuring? Maybe not the output but something physical to do with the head and how it is ejecting droplets? When installing a new head, one step requires an incredibly long string to be put into the software which varies with each head. Perhaps this string is setting up the initial calibration based on the new head being put in place, which means they “calibrated” the head without ink in some manner?
