Prepress procedure with enhanced gamut for printing systems

摘要

This procedure consists in a 2^nd stage in which the "Pantone" scale is reproduced in the own chart with the cyan, magenta and yellow colours from performing a pure reduction synthesis of colours.;It also consists in a 3^rd stage with three steps. The first step is about the digital separation of the part composed with the CYM colours from that of the "Pantone" colours; the second step consists of processing the part that includes the CYM colours, using a TetraChtome output profile made up by the inks of enhanced gamut and a TetraChrome input profile made up by an owner profile with 7000 spectrometric inputs to obtain a file of suitable colours to its reproduction with inks of enhanced gamut or normal gamut and the third step is is about the transformation of the "Pantone" colours from the original file to the own colour chart.;This procedure uses a software that provides a rippeared medium of the in the third and fourth stages the software used provides a rippeared medium of the colour in 16 bits.
