![]() Given possible sources of error, it is fair to attach a margin of error of +/- 10% to our results. Long periods of being left on, automatic cleaning, and manual cleaning cycles all play a role in overall ink usage. Also, how often a printer is used will change ink usage slightly. “Real world” variables – The types of images printed can make a difference in the overall ink usage.Also, the printer stops immediately or very soon after the display shows no ink. From observations during the printing phase however, the display was consistent in its changes downward. Inaccuracy of the remaining cartridge usage figures – The accuracy of the Canon Status Monitor could be called into question.We acknowledge that there are potential errors in testing and calculations. If you pay more or less for inks, just use the above equation, and substutite your cost. Updated Jan 2021.Įquation: (Cartridge per Square Inch) x (Square Inches) x (Cost of one ink cartridge) = Ink Cost Per Print Using the CEU figures, we’ve extrapolated the cost of ink by print size (roughly 95% coverage) PrinterĬaluclated using $16.99 per ink cartridge. The cartridge usage of each printer is listed below Printer Sum of the % used for remaining tanks / 100 = CEU of remaining tanksĬEU remaining + Cartridges changed / 200 = CEU of 8x10 printĬEU of 8x10 print / 80 square inches = CEU per Square Inch Summary The final results focus on actual yields, not questions of lost milliliters in spent cartridges. If the printer quits then effectively the cartridge has run dry. (See end section for all screen grabs)įor the purpose of this experiment, the question of how much ink is left in an "empty cartridge" is moot. That proved helpful in making estimates of ink left per cartridge. From previous experience we observed the printer quitting immediately or just after a cartridge displayed "dry". It was assumed that the Status Monitor display offered an acceptably accurate account of how much ink was in the cartridges. From the screen grab, a graph breaking the ink level into 10% increments was used to make an estimate of ink remaining. Remaining cartridges were evaluated for amount remaining and thus volume usedįor final ink estimates, a screen capture was made of the Canon Status Monitor, which shows a display of ink cartridge status.Number of cartridges replaced (including the starting cartridge) was tallied.New cartridges were installed at the beginning of the test. ![]() The ink usage was equated to amount per square inch and then converted to specific photo sizes. From that information, total use of ink in equivalent number of ink cartridges used was obtained. At the 200th print, a count was made of ink cartridges used plus an estimate of remaining ink cartridges. Inks were changed only when the printer stopped and indicated an empty tank. Prints were made using the High Quality setting within a color- managed workflow. The image was resized to 8” x 10” at 300ppi. A pre-primed printer was loaded with new and previously unopened ink cartridges. The montage of photos in Atkinson’s image provided around 95% coverage, used a wide variety of colors, and presented what amounts to a worst-case scenario of ink usage. Two hundred 8x10 prints of Bill Atkinson’s printer test were made. Further, we hope to spark more discussion and debate about the merits of inkjet printing in light of its unique ability to offer on-demand continuous tone photo reproductions that will last many decades. The goal is to determine the cost for various popular print sizes, and to report those numbers. Do the majority of end users simply not care about the cost or do they know something that is missing from the discussion? This report looks at the cost of ink per square inch for the Canon PRO-100. Still, inkjet printer sales and printing continue to increase, and studies indicate this trend will continue in the short and mid-term. With claims of ink costing five to ten thousand dollars per gallon, it’s not a mystery why the debate continues. The “true cost of inkjet printing” is a source of constant debate in the media and on web forums. This chart shows the cost of ink used in making prints:Ĭaluclated using $16.99 per ink cartridge. The choice to pursue photo inkjet printing is in the end an individual economic choice. The objective is to share a realistic cost-per-print-vision with inkjet users. From that figure, we extrapolated ink usage per square inch. Using the Canon PRO-100, we conducted a series of print tests to determine how much ink is used in a full coverage 8”x10” print. This report addresses concerns and arguments about the true cost of ink in desktop photo printing. This report is the from a series covering the costs of desktop inkjet printing.
