Selection according to the “weakest link in the chain”
Independent on the printing technique
A minimum of number of dyes must give the maximum number of shades
Such a selection is called a core range
Result of a time-consuming screening of the sublimation dyes
Subli Inks - Fastnesses The light fastnesses have been measured at the maximal recommended dye concentration and a dilution of 1:9 (B: bluer). All other fastnesses have been measured at the maximal recommended dye concentration
These settings are standard for 100% PES fabrics. Depending on the substrate (fabric or hard substrate), other conditions may be more appropriate. In case of fragile substrate, it is indeed possible to reduce the temperature and still obtain an optimal transfer by increasing the transfer time.
The light fastness reachable by the dye-sub inks is in general limited. Thus a UV-protector is recommended and it is in any case necessary to test whether the end product fulfils the requirements of the application. No extrapolation for outdoor fastness should be drawn from the light fastness rating performed according to the ISO105-B02 norm, which attempts to reproduce indoor light conditions.
