New XM screening is where fixed size dots are distributed in a dispersed pattern in a subset of the positions where AM dots will later appear, said Lucid Dream Software.
The I-Tone Logo and I-Tone Hybrid screening is based on a cross modulated XM screening technology that uses the Agfa Balanced Screening AM half-toning in the mid-tones.
It smoothly changes to a modulated FM dispersion based on the AM angle and the minimum dot size in the highlights and shadows, said Lucid Dream.
Fixed size dots are distributed in a dispersed pattern in a subset of the positions where AM dots would normally appear and higher screen frequencies can be used than otherwise possible, it is claimed.
Without the fixed size highlights there would be a sudden transition when the smallest stable dot appears in each halftone cell and that transition becomes a bigger tone jump with higher frequency.
With fixed dot sizes, the density of those cells are finely controlled in the extreme highlights, allowing for a smooth transition, added the company.
Lucid Dream explained that I-Tone Hybrid screening allows users to print highlights, which truly fade to zero and have control over subtle pastels and shadings previously almost impossible to achieve in print production.
