Aron Gent Recalibration

For the past twenty years I have been a professional photography printer using Epson inkjet printers. When the massive ink cartridges need to be replaced there remains roughly 10% of ink which I have been saving for the past ten years. I use this Epson ink that I use in my day job to make abstract color studies on watercolor paper in my free time in the evenings or on weekends. Sometimes the study is complete in one attempt, sometimes up to five attempts with the same sheet of paper are needed for it to be complete and sometimes the back becomes the front for it to be a completed study.
