Hey guys, Im new on here too. The question I have is, how do I set up a white underbase for a 4 color process job, going on a colored garment. I know how to do the seperations, i use PS CS4, and it seams to work fine if we are gonna print on white shirts, but I would like to know how to set it up, so I can take my art and put it anything. I am a graphic designer, but I just started working for one of my clients print shops (need more $$$) so the art I know, its just little things I need to know to get it from my screen to "real" screen. If you can help please let me know, or if you know any sites with steps on this, that would be great! thanks alot guys! CHEERS!

I use UltraSeps, but if you're trying to do it through Photoshop, I'd say convert a copy of your image to grayscale and possibly choke it one or two pixels.

forgive me if i am dumb, but what do you mean choke it? there are is so much new terminology in the printing world, do you mean adjust levels?

"choke" means to make the image smaller usually by 1 pixel some put a 2 pixel choke on the art, so when you register the other colors ontop the white doesnt show if one or more colors aren't lined up perfect

That's the way I've done and it can work well. You can tweak it by adjusting the levels using curves/brightness/contrast.
And invert it.

this is standard but keep in mind the amount choked would depend on image resolution (if it's a bitmap) and the print shops tolerance on press.

yes , **DISCLAIMER HERE** - this is a standard and may not work well for every shop...you need to test to see what works for your perticular needs. **END DISCLAIMER HERE**

I would think you would want to use a solid fill behind the 4 color process, not dependant on the halftone dots, since ideally, they should mix together on press a bit. I would make a solid image for behind the four color, then use a discharge white underneath for the base, flash, then the 4 color process wet-on-wet on top.

of course this won't work on a four color press.

what kind of press does your friend have?
