No, I'm not.  Dithering involves the use of more than one pixel to create
the impression of some color intermediate between those pixels.  A dithered
image contains adjacent pixels of slightly different colors that can create
the illusion of greater gamut when the image is examined at a distance.  In
dithered digital images, you can expand the image until the individual
pixels are readily visible, and you can see the dithering as alternating
colors of adjacent pixels.  It looks like grain from intermediate distances.

Dithering is much more noticeable than ordinary non-dithered printing,
because dithers occupy several pixels, not just one pixel of several dots.
The difference in size can be an order of magnitude.
