Plural of aquatone; multiple prints or images made using the aquatone color printing process.
Plural form of 'aquatone,' combining 'aqua' (water) and 'tone' (color shade). The plural maintains the singular form's 20th-century coinage.
If you look at vintage comic books from the 1960s and hold them up to light, you can sometimes see the dot patterns from aquatone printing—each color was applied separately, and imperfect registration created those distinctive slightly-blurry color halos that became iconic to the era.
