Wellllllll.......
I read that somewere and it made sense. But you do have a point.
Well, you know what they say about believing everything you read. ;-)
In fairness, you are not the first to say it and certainly won't be the
last - it was a common view when the printers first appeared. Some
folks on the Epson mailing list have actually measured the ink
consumption at the higher dot resolution and proved its the same that
way.
in my testing 1440 is darker than 720, but 2880 is little different.
I thought that the dots were always about the same, and the different
dpi setting controlled the number and spacing of the printing passes.
No, most of the Epson printers from the past couple of years handle at
least three different dot sizes, although the manuals and specifications
only ever mention the smallest. You need to find the complete service
manual to find out what the larger dot sizes are. The printer driver
will use these larger dots for lower resolutions and also to block fill
large areas of the same colour, such as synthetic images - charts and
diagrams etc. The highest resolution that any Epson printer will
achieve is 720ppi in each axis (large format professional Epsons limit
at 360ppi), irrespective of the stated dot density. This is the native
resolution of the printer driver and the higher dot resolution merely
permits finer colours to be represented at that resolution.
