There is a question to which I have not seen an answer, but is perhaps relevant to this discussion. What is the actual image resolution of an Epson printer? With a 300 dpi dye diffusion printer you know that you have 300 contone pixels per inch, but what is the equivalent figure for an Epson 720 x 1440 dpi Epson printer? You need to build up individual CMYK densities to give the illusion of continuous tone colour, so even with variable size droplets you need to place several droplets side by side to build up one 'pixel'. Is this performed on a fixed grid, as with halftone screening, or do we get variable sized 'pixels' calculated on the fly? Is there a simple relationship between the nominal dpi resolution of the printer, and the resolution of detail in the colour image that we can print with it?
I am also intrigued by the suggestion that the driver merely dumps excess resolution. Is this certain, or does the driver actually recompute the data to give a best fit to the selected picture dimensions?
