Halftone
ハーフトーン（網点） / 1880s– / Technique / Print Expression
Halftone converts continuous tone into regularly spaced dots of changing size so it can be printed; from a distance they return to tone, while enlargement reveals the screen as material.
Large and small dots on one fixed pitch / Light and shade made by dot area / Rosettes from differently angled color screens / An image that changes between normal and magnified viewing
