HANS – the Neugebauer Primary based color separation and halftoning print control approach – was presented in broad terms at CIC18. The present paper provides an in–depth look at how HANS color separation can be optimized, what level of variety it provides access to and how it can be used for direct optimization of print attributes. The results show that even in the case of having only three colorants – CMY, where current approaches lead to unique solutions, HANS provides significant metamer sets that lead to variety in print attributes such as the 12.7% ink use range show in the results.
