i would underbase it if you want a clean solid looking lime print. without the under base, if the sport grey is a lighter version of Heather grey (i could be mistaken), you will see the texture/mix in the fabric in your print. It may only show slightly and may not be an issue. always best to test if you're doing something new and not sure of the results.

If we had a short run, we would print-flash-print with just the lime green screen. If it was a larger order, we would underbase w/ white, flash, and overprint the green.

Why would it matter the order size? You're still print, flash, printing... just one is 1 color twice the other is 2 colors once? I'm confused on what the difference is and why it would matter?

i have always found you get a sharper more vibrant print using an under base rather then the p/f/p of the same screen. especially with bright color inks, they tend not to be very opaque.

when you p/f/p the same screen you are guaranteeing there will be bleeding, making the print larger (it's minimal but i do notice the difference)
Jeron,

We have both manual and automatic equipment. If this were an order for more than a dozen shirts, we would print it on our automatic.

If I have an order for 36 shirts, we would P-F-P with just one screen. This would require the shirt making two revolutions around the press.
The additional printing time would be more than offset by not having to make a white under base screen (artwork, positive, exposure time and related costs, registering two screens, reclaiming a second screen, etc.)

If the order were for 200 shirts, then making a white under base screen and it's related costs would be more efficient, productive and profitable than running each shirt around the press twice (and effectively doubling the production time).
Oh ok... that makes sense... I didn't think about an automatic and screen costs... learn something every day lol..
