As mentioned in another thread, I am trying to determine the papers and approaches that deliver the widest gamuts. At present I believe the Epson Ultrachrome K3 inkset delivers a much wider gamut than any lightjet paper, and a product with 2-3 times the archival properties. The cost is more , but if longevity and wide gamut are prioritities , then there is little choice.
This taken, there is considerable flux in the market with a vast range of new products coming on line.
It seems that to push boundaries using the excellent K3 inks or equivalents from Roland or others,
paper, paper coatings , profiles and RIPS are all critical.
With all these parameters in a state of rapid flux a state of equilibrium is still a long way off.
My current observation is that the results I am seeing today,in general, far exceed the quality of accessible analogue technologies.
Lightjet is a transitional technology that will persist at the low end of the market with its low cost and acceptable visual qualities.In the long term it may be it's problematic environmental attributes that lead to it's ultimate demise.
