Weird...my long typed answer blipped. Forgive me if I repeat myself.
This is a really long answer and frankly I just don't do a lot of two and three color because it's really a pain w/ the Yudu. It's the weakest link on this machine. BUT a lot of it has to do with user error (mine) as well. Princessaam may know more than I do. You may want to post this question as a new thread to see if you can get her attention.
I have two answers for you. 1. Use registration marks on your transparency. Registration marks are small crosses in the corner of multiple transparencies on all four corners of your images about 1" away from your image. Each color has it's own layer and you will enjoy haveing a screen for each color. Print your images on transparency. Line up crosses starting with bottom layer tape to light table. Cont. to tape each layer, moving your tape slightly so they aren't on top of the layer below. You MUST line up the registration marks perfectly. Now flip all but the bottom transparency, burn and remove transparency and screen. Flip down the next layer, place new screen, burn and repeat for all your layers. Check finished screens all your registration marks still in line. You may need to hold them up to a light to look through the registration marks. They must be perfect or it will be milimeters off and give you a blurred picture look. Tape off registrations marks before you pull or use your blackout.
2. Shim your lid up. Go slow and careful. look for the light through your screen as you lower your lid just over the tshirt. Make sure your shirt is totally secure so when you lift your lid it doesn't come with it. Put your lid down (without ink) and give it a little wiggle...can you see your edge...then you aren't aligned. Play with it and when you give up just go for it. Even the PC employees who had the Beta said they would like to see the lid tightened and have less play.
Shims can be wood working biscuits, rolled up paper, anything that will take the play out of the lid.
If I had to modify or improve the Yudu...
I would take the play out of the lid
I would have pegs for landscape and portrait
I would have a faux platen that would have placement for cards. It would create the depth of the platen and have a very slight edges to hold the cards.
I would make the fan stronger, so it would dry a screen. *sorry girls but the fan just isn't strong enough* grab your hair dryer.
Hope this helps. Multiple color is not for beginners!! I hate it personally. See my Newf...all black!!
