Nyloflex Next high output UV technology from the Flint Group is said to be able to generate unique element shapes with precisely reproduced surfaces, commonly known as flat top dots - providing increased tonal range with an optimised surface texture to greatly improve ink laydown and solid ink density.
All the processes currently used to produce a plate with a flat top profile are designed to prevent oxygen exchange between ambient air and photopolymerisable layer during the exposure step, either by blocking it at the plate surface with barrier films or by displacing the oxygen with inert gases.
Compared with alternative systems, the main advantage of the new nyloflex technology is that it does not involve the use of inert gases with all its risks and does not require additional expensive consumables. Furthermore there are no processing steps added to the standard digital plate workflow, such as film or negative film lamination.
The only change required with Next is the addition of an advanced high energy UV light source, which accelerates the polymerisation in the image areas so that the competitive termination reaction with oxygen becomes insignificant.
