Is there a difference of quality? I have like 4 wooden ones, but locally they sell the aluminum screens for a few bucks cheaper. So what's the difference, if any, and what do you use?

Aluminium is normally lighter (which is generally neither here nor there), lasts longer (won't warp), easier to clean (non-porous, so ink is easier to wipe off), and costs a little more.

From my supplier aluminium is about 15-20% more expensive than cedar in standard sizes (i.e. the kind of thing you'd use for t-shirt printing), but cheaper in very large screens (not relevant for most people on these forums).

Personally I prefer aluminium - the price difference isn't significant (especially for such a re-useable piece of equipment) and they're more pleasant to work with.

I use both though - there's nothing wrong with wooden screens (assuming they're a high quality wood and well joined). Next time you need a screen I'd recommend you try aluminium and decide for yourself - it's at least worth trying.

Screens are very much a matter of use what you've got though - they're not worth replacing until they actually physically require it. Most of the screens I use are wood, because that's what's there, but the new screens I buy will be aluminium.

thanks for the feedback, im sure the next ones I buy will be a higher mesh count for sure (230-ish rather than 110-ish), and also aluminum.

also wood will eventually start to warp. once the frame is warped your limited to one color prints with that frame if your even able to do that. Aluminum is the way to go for sure and you can have them restretched when the mesh tears.

Aluminum is the only way to go. If you have wood screens that aren't warped yet.....use them until they go bad. You'll eventually want a variety of mesh counts as you grow your business. The mesh count you use will be determined by the graphic you want to print.

The mesh count you use will be determined by the graphic you want to print.

So Jay, would you mind briefly summarising the different types of graphics you are referring to, and which mesh counts suit which styles?

Cheers

so what makes wooden screens warp? how long, on average does it take for them to warp, and is there anything to do to prolong their life (like store them a certain way)?

 

[Vtec44]

Well, they warp typically from shrinking and expanding because of water. They come in contact with water when you clean the screen.

Storing them in a humidity controlled environment helps (especially if they're screens your saving with designs on).

But sooner or later, they'll need to be replaced, or rescreened.

 

[RAHchills]

hey thanks guys, I was worried there for a minute. I'm not planning to reclaim my screens anytime soon and they're in a humidity controlled environment.

Now I know about the warp issue, though, so I may pick up some aluminum screens in the future, just to be safe.

 

[Fluid]

you wont be sorry

so far I've only been doing one color shirts, and i think two of my woodscreens are already warped, but they dont seem to affect the printing. they just aren't level when I lay it down flat. I'll be converting to aluminum as soon as i can anyway, so no worries. thanks for everyone's input.

A little bit of warping may not have any real effect on a one colour print. If you're registering a multi-colour print, obviously it's potentially a much bigger deal. Also, they can eventually get extremely warped - to the point where they don't even lay flat enough to do a one colour print, because you can't get even ink coverage across the mesh. But as you've noticed, a little bit of warping doesn't necessarily mean you have to immediately discard the screen.
