The image to the left represents how the human eye would see the gradient on the right, in tone, from a sufficient distance.
"Halftone is the reprographic technique that simulates continuous tone imagery through the use of dots, varying either in size or in spacing.[1] 'Halftone' can also be used to refer specifically to the image that is produced by this process.[1]"

Tone usage in 'Pad Printing' process;
Pad printed images using tone can be very effective. 4 colour process images can be achieved through tone. The resolution on jobs that have a small printing position can be low.
Larger size print areas will obviously be more effective due to the fact that there is more area for the dots to fill.
Gradients that involve two colours, rather than one shade, get printed as duo tones which involves both colours involved being separated and produces as individual spot colour halftones.
