You're probably right, tests are (mostly) based on 5% coverage but not yet on ISO norms.websnail said:Really? I was under the impression that Canon tests were different from the Epson ones, or at least that was true when I was looking at this 6+ months back.
There was an interesting thing at the Epson site about the ink topic:
"Epson uses internal test standards for inkjet yield testing because there are not yet any
international or common industry standards. Epson fully supports the efforts of the
International Standards Organization (ISO) to develop such standards, which may be finalized
in 2006. Epson will implement the new ISO standards after they are finalized. In the absence
of international standards, Epson encourages users to consider independent third party data
and to use manufacturers data primarily as a reference point between printers from the same
manufacturer."
