Both ISO coated and ISO web coated ECI profiles also produce anomalies
in saturated blues when used with relative colorimetric rendering
intent. Can anybody clarify the these profiles built only to be used in
the perceptual mode , or if these profiles were built to produce extra
chroma/saturation in the relative mode , which may explain the colour shift?
Not only eci profiles produce anormalies, not only in saturated blues
and not only in one intent ;-)
