Ever since we invested in our B2 litho printing press we have used stochastic screening to achieve higher quality print and and more faithful colour reproduction.
Screening is what enables the four process colours (Cyan, Magenta, Yellow and Black) to be used in different strengths and percentages to achieve just about any other colour or tone.
The most widely used form of screening by commercial printers is ‘AM Screening’, a process whereby the the position and angle of dots remains fixed, but the size of each dot is varied to reproduce the effect of continuous tone.
Stochastic screening, on the other hand, utilises ‘FM screening’ also uses dots of the same size, but instead of being set to fixed angles places them randomly in varying amounts to reproduce continuous tone.
With the FM method it is possible to produce very fine detailed print and eliminate the moiré and broken lines associated with AM screening.
At Absolute we have invested in the SPEKTA screening technology, an advanced system which boasts higher dots per inch (DPI) and truer reproduction across the colour spectrum.
Moiré no more.
The placement of dots is always random with SPEKTA which means there are no screen angles to contend with. As a result, SPEKTA avoids the moiré resulting from interference patterns between screen angles and items such as lace cloth, stereo speaker mesh, and CRT screenshots. It also eliminates the rosette moiré that can occur in dark grey or black areas.
More in the mid-tones
SPEKTA does a better job of bringing out the vibrancy in the mid-tones for skin colours and other areas where true-to-life colour is required.
Finesse in the fine details
SPEKTA demonstrates its superiority in reproducing fine details, such as those required in art and photography reproduction, and it improves the rendition of lines that are created with halftones.
The SPEKTA technology can also better reproduce colours traditionally beyond the process CMYK capabilities which were only possible by the printing of an additional ‘spot’ colour.
