Air, what do you mean by light ink? is it the color that is light? If it is the color, you can use Superwhite as your base for color mixing, because superwhite has better opacity than other bases and you can only mix light colors to the superwhite. Take note that you should be careful in mixing pigments to superwhite because your print might bleed during washing, this is based on the Superwhite of TULCO, not sure of the others.

If you're printing on a 50/50 shirt, yeah you could start with a light flash, but otherwise if you're printing on a 100% cotton, you'd more than likely print/flash/print/cure.

I am doing my first multi colored job Monday. What does flashing the shirt first do?

Use the appropriate emulsion...there are emulsions for plastisol inks as well as emulsions for use with waterbased inks/discharge inks.
You always want to have your registration locked in no matter what.

A flash unit is used to gell an ink so that if you print and it's not enough coverage on the shirt, you 'flash it' just long enough for the heat to dry to the touch, not cure, then you let it cool down, then print your next color or the next layer of color.
If you have colors that touch, you need to flash so that your colors don't dirty.
Or if you print a underbase, you'll need to flash before you print your top colors.
Flash units are also used by some as their final cure.

The only time you'd need/want to flash a shirt before printing is if it's a 50/50 so that the heat shrinks it (if it's going to) before you start laying ink and getting a shift (movement) if you then flash after laying down your first layer.
