This is a second order FM screen (Kodak Staccato). In a first order FM screen, dots of the same size are added to simulate darker tones. In a second order FM screen, dots of the same size are added to simulate darker tones – however at a certain tone value no more dots are added. Instead the existing dots simply grow, in one or two directions, in order to simulate darker tones.
