Using the Cartridge Unit Equivalent figures, we've extrapolated the cost of ink by print size (roughly 100% coverage) PrinterĮquation: (Square Inches Printed) x (CEU per Square Inch) x (Cost of one ink cartridge) = Ink Cost Per Print Sources of Error Our calculations are based on the a price of $30.50 percartridge. The CEU of the R3000 for 200 satin 8x10 prints is 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.

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 1440 x 720 dpi quality, High Speed printing turned on, 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 100% 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 two Epson desktop printers. 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. PK = Photo black ink, MK = Matte black ink Testing Methods Preface This chart shows the cost of ink used in making prints: Cost of Printing Per Page Chart 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 Epson Stylus R3000, 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.
