The use of ink degradents has long been a practice in the industry. And, yes, we do find that it does reduce the amount of haze remover used. Please remember that haze removers are not necessarily an environmental problem, depending on your wastewater situation, but they are considered a safety hazard due to their caustic nature.
Regarding the use of solvent based inks -- there is no tried and true answer to this question. The use of solvent based ink over other technologies depends on several factors: nature of the substrate as well as the intended use of the product. Oftentimes, one can take the same substrate and print it with UV curables, however, solvent inks may be used on the exact same substrate if it is to be hung outdoors for a long time, or used in an application that requires resistance to chemicals, such as safety signage. These are just two examples. As UV ink systems are becoming more widely accepted, screen printers are integrating them into their operations. However, solvent inks still maintain a high percentage of the market place in screen printing applications.
