[filmscanners] RE: Compact Cameras



David,

I am sure that we would all like to know the answer or at least get
additional information as to the difference between RIP and the print
driver.  However, I am equally sure that software is NOT ALWAYS
software.  Some software is better than other software; some software
has features and functions that other software of the same general
category do not; and some software is more sophisticated than other
software.  The resampling method used by the Epson drivers (if they use
the "nearest neighbor" method) is not the same or as good as Photoshop's
Bicubic method or Genuine Fractal's method.

Unlike most Epson print drivers, I believe RIPs allow one to exercise
additional controls over the type of halftone screen or dithering is to
be applied to the image both in terms of the size of the dots, the shape
of the dots, and the nature of the matrix used in the halftone cells.
But I could be wrong about this.  Moreover, I believe that many quality
service bureaus and labs as well as printers employ RIPs.
