Grandad35,
You're right about the "Photo Yellow" since this colour is already very light, the human eye cannot determine between dark and light yellow at all. However: Canon's print technology using 3 different dot sizes for magenta, cyan (and on the MP980 grey) the need for extra photo versions of these colours is now negligible. On the Canon IP5300, IP4500, MX850 (all using the same printhead) you can actually see three bands (dark, middle , light) of both cyan and magenta mimicking the previously used light magenta and light cyan when printing the nozzle check.
One could ask: why not use three types of dot sizes for the photoblack (like the cyan and magenta nozzles: 5, 3 and 1 pl), so we can enjoy black, grey, photogrey, so you can actually print neutral b/w with only one photoblack cartridge ?
