Staccato NX
Staccato NX is a configurable second-order FM screening intended for
use with Flexcel NX media for packaging applications.
Staccato NX introduces FM screens for use with Flexcel NX media to
address the needs of the packaging sector. In particular, it lets you use
extended color sets (beyond CMYK), while avoiding AM screening
moiré in the overprints.
Staccato NX consists of a set of preconfigured FM screens that can be
selected in Prinergy. Staccato NX gives you a choice of minimum
highlight and shadow dot size or dot width, and a choice of midtone
frequencies. Screens are specified in terms of pixels for minimum
highlight and shadow dot size, and equivalent line screen ruling (lines
per inch) for midtone frequency.

About screen systems
Screen systems contain an optimal set of screening characteristics for
a particular screening requirement. Predetermining the relationship
among screen angles, screen rulings, and the screens to which these
are assigned reduces the occurrence of screen artifacts.
Screen angles are calculated as in the above illustration.

Maxtone
This screen system forms a rosette among black, magenta, and cyan by
screening these separations at equal rulings with nominal angles of
75°, 15°, and 135°. The yellow separation is screened at 0° with a ruling
slightly higher than the other separations to reduce moiré. In the
default angle assignment, black, as the most dominant color, is
screened at 135°.
This system is susceptible to moiré in smooth tints of two separation
pairs: cyan-yellow (greens) and magenta-yellow (peach tones). Angle
swapping allows moiré susceptibility to be shifted from one of these
separation pairs to the other. For applications with dominant peach
tones, set magenta to 135°.
This system has been formulated for best performance on output
devices to provide even, low-moiré flat tints, especially on large-format
