This may be a naive question...but does this mean that if you have the data available from high resolution scanning that the best print results would be obtained by sending the printer an image at 720 or 1440 ppi rather than 300 or 360? Howard << Upsampling is NOT implemented directly, but is a process of the dot placement algorithm which Epson uses, which redistributes the quantisation noise in the image to retain as much detail as possible. Thus, in your example of a 457ppi image printed on an Epson printer, if the printer is using 720ppi, it will not be directly resampled and the full detail from the original resolution is retained. You can check this, as I have on several occasions, by the use of synthetic test patterns and assessing exactly where the output spatial frequencies are aliased to. Providing that the input test pattern is lower than the limiting resolution of the dot pattern, there is no resampling and only the noise spectrum in the image is reshaped. - -- Kennedy >> - Turn off HTML mail features.
