Photoshop tech help plz

[tripperfunster]

I'm entering a t-shirt design contest, and the rules (or rather, tech guidlines) are thus:

Use Pantone Solid Coated color swatches for your design or else we will have to convert your colors
Maximum of 6 spot colors
Gradients & Halftones:
Photoshop users, make certain that your halftones are 30 LPI or larger for a full-size design at 300 DPI.


What does that mean? I plan to ink my design (traditional media) then upload it and colour it in photoshop. Is there anything I need to do to make sure I stay within these parameters??

thanks in advance!

BTW, LPI means "lines per inch" - it has to do with screen printing. It's resolution, basically. The way to do halftones in Photoshop is to convert one of your channels to grayscale and then to bitmap, which then lets you select the LPI. But I don't fully get all that so I shouldn't give out half-baked advice about how to do it. :)
