correct. the reason i like IA Light when using white ink is because some RIPs today don't put any white ink under black ink. the problem with this is that the "dark" shirt pretreats are designed to hold white ink, and then the cmyk bonds to the white. however, when white ink isn't present, (under black ink), there tends to be increased fading of the black ink after washing.
since IA Light keeps cmyk vivid even after washing, AND it holds white ink, it is the best of both worlds. like i said before, though, i haven't tested IA Light on anything darker than charcoal. other printers are getting good results on navy and black shirts, so it must be possible. i suggest to do your own testing so you know what works best in your environment.
IA Light on Dark Blue Navy = need more than 50ml pretreat to get solid white, i can still get decent white on 30ml, but there will some area with low opacity white like not enough pretreat, so safe one is 50ml
IA Dark on Dark Blue Navy = need arround 30-35ml for my shirt
to Brian: are this normal? so i guess realy need to stick for dark pretreat for Dark Garment..... are IA Light have diffrent formula or something?
but since i printing Black on Dark Navy..... i have no choice to use IA light.... i use Khotari RIP too.... no white ink under black
here are the result on dark Navy, using Light IA 40ml
this is after 1 wash
notice some are didint have enough coverage, if using dark IA coverage of white ink are better.....
