An E-Factor of 9+ is not demanding and is representative of how commodity printers reproduce color work. Six of the ten of the largest Web to Print printers audited in 2018 had an E-Factor of 9 or greater. You get what you pay for, and printers that reproduce color with E-Factors of 9 or more typically do not monitor their process hence the high E-Factor. Based on our 2017 TAGA Research, 95% of print buyers would not accept printed color at a 9 or greater E-Factor. This type of printer is probably running on a very low-profit margin and barely getting by financially due to much of their production requiring re-run and losing repeat business. There is no guarantee regarding color reproduction with printers that do not control or monitor their process.
