Murad Kalal, channel sales manager of Esko in South Asia, attributes the reproduction quality improvement to the smaller half-tone dots of digital flexo plates that lead to smaller dot gain on press and an extended tonal range.
Vignettes actually print 100% to 0%, and there is incredible detail in the images with no dot gain. Perfect ink to ink registration is achieved every time, with super small reverse or positive type down to 1 point.
CCC cabinets create standardized viewing conditions for the assessment of colours ink weight register and dot gain. A neutral grey concave viewing deck (unique to VeriVide) eliminates specular reflection to maximize colour and quality control.
There are actually several reasons which decrease the predication accuracy of the spectral Neugebauer model, such as the dot gain, light scattering and penetration, and nonlinearity between the summed and the individual primaries' reflectances.
It is very difficult to classify all the parameters that can and do affect on print quality, but it is certain that the dot gain is surely one of the most important parameters that define the quality of printing product.
