¹ Quoted yields are extrapolated based on Epson original methodology from the print simulation of Test Patterns provided in ISO/IEC 29103 based on the inks included with this printer and photos printed in a 10x15 cm format. Quoted yields are NOT based on ISO/IEC29102. Quoted yields may vary depending on the images that you are printing, the paper type that you are using, the frequency of your prints and environmental conditions such as temperature. During the initial printer setup, a certain amount of ink is used to fill the print head's nozzles, therefore the yield of the initial bundled set can be lower. 2. Print permanence ratings are based on accelerated testing of prints on specialty media stored in archival sleeves in album storage. Actual print stability will vary according to the media, printed image, display conditions, light intensity, humidity, and atmospheric conditions. Epson does not guarantee longevity of prints.
