I'm curious what distance in points do others use to choke a white underbase? I have played around with different numbers. Working in Illustrator and Corel, I have used as a little as 1 point which translates to .5 on either side of center.

I'm trying to keep the edge as clean/crisp as possible when the top color is applied.

Thanks!

We used to be able to just put a piece of clear plastic between the transparency and the screen but I would think that 1 to 2 is max... I have not screen printed in some years but this is what I remember.. I have also been successful in the past with not underbasing in white but a color closer to the shirt color or the design color... Just my $.02

I remember a reprographics company that used to do that choke in their darkroom, been awhile. I like the suggestion of the ink close to shirt color.

What happens if you print flash print the color you want to end up with? Wouldn't be any registration issues.

Whatever works for you...1-2pts is typical, in pixels - it depends what your resolution is?

We normally use 1 pt. inside stroke.

We tend to do .5pt for underbases.

The places i've worked for usually did 2 to 3 point choke white or 1 to 2 point stroke on the top color. Flash curing should not change the registeration at all. Since the shirt is stuck to the platen with spraytack. Never been a problem on either hand printed presses or automatics.
As for the choke/spreads it also depends on the design, colors and shirt colors. And the talent of your printer.
