Digitally Modulated II (DM-II) Screening
400-500 lpi on CtP devices!!

"As an experienced user of Auraia-II from its early development I really feel it‟s one of the industry‟s most productive advancements to be released in the CtP market", comments Brian Parkes, Parkes Print & Design MD. "We still use exactly the same plates, low-chem plate processor, press inks and blankets and the press minder loves it. In fact it simply makes quality print easier, flat tints are amazingly smooth ('unheard of for FM Screens') and press productivity is improved as a result."

Auraia-II screening, named after the Greek word for 'beautiful' ('ὡραῖος'), is Hamillroad's second generation Digitally Modulated Screening (PDF - 128KB). Built on the foundations of Auraia-I, Auraia-II perfects stochastic screening as it not only achieves the high level of image detail long associated with FM stochastic screening, but also produces ultra smooth flat tints that are as smooth or smoother than AM conventional screening.

Taking advantage of the immense computing power now available, DM Screening (PDF - 128 KB) is so named because it digitally modulates each and every pixel it produces, precisely controlling not only the dots in each separation, but also between the separations so as to completely eliminate noise. It does this through the use of a "stochastic rosette", which interleaves the screens in all the separations. By doing so, it eliminates noise (and moiré). The "stochastic rosette" also maximises the amount of ink-on-paper and minimises the amount of ink-on-ink, which expands the available color gamut whilst eliminating color shifts on mis-registration.
