Hue and saturation shifts in soft proof and non impact images

In graphic reproduction posibility of reproducing some non standard e.g. tertiar colors can be troublesome. Introducing or implementing special (non process) additional colors in graphic reproduction process can be usefull and accomodating in “colorfulness, tone reproduction and overall density range”, but can cause additional separation and various other production problems. From another view, reproduction in standard cmyk subdues to achromatic principles (according tom ISO), so compromise has to be carried out, regardless to theoretical statements. A nonstandard worfl ow applied, recalculations conduced the differences that occured in observed systems. Irrespective to this rearanged workfl ow, for achieving more adoptable results for such non standard purposes, custom procedures have to be involved.
