It's an added step and a step that something can go wrong as you have to tape the positive to the carrier sheet.
With the inverted reg marks on the glass, the reg marks on your film line butt-to-butt with the ones on the glass.
Print film, place on glass (use tack cloth from paint dept in home depot/lowes on glass, removes lint and when you add pressure, will help the film stick to glass) burn and you're done.
No film to peel from the carrier later.. the carriers also have a life before the pre-punched holes start to loosen and you need to buy more carriers. I love the tr-loc but the initial high cost and then it uses consumables turns many ppl off. It is however the best option for a full blown factory who can absorb those costs a little easier than you or i.

I love this subject. I am going to go out and take some pics of what I have currently and what I'm thinking of doing. My artist and I have thought about doing the hole punch idea. Your thinking of lining up the job on an FPU of sorts, then punching them out right? I just really wonder if there will be any sliding or moving of the film when the punch is penetrating all of the film, or if there is a way to do it separate and still not lose registration. I like the hole punch but I'm not ready to go down that road yet and I have some other areas I'd like to explore before getting to it because I think there are better/easier ways.
Right now, I really like the system John52 has in his shop. I am going to go out and take a pic of what my FPU looks like, and then a pic of what I want it to look like in the MHM FPU. But the only downside to the MHM FPU is I'm not using an MHM machine and the pallet jig on press will not be exactly like the FPU.
I really want to get my aluminum piece cut or someone to let me buy their Tri-loc pallet jig. Then I'd have one of the best DIY regi systems around. Ok, I'm going to take some pics.

I think the hardest part of the whole system is replicating the film positioning part on press.
MHM's do this with pins on the screen that lock into the same place on every head. If I didn't
have an MHM I'd be looking for a way to replicate that. Seems much easier than the pallet jig
setup. Just my $0.02.

eb, you are totally right. MHM's system makes WAY more sense. Take a look at offset presses, the plates lock into the same position, registration is done OFF the press.
alan802:
I have also looked at retrofitting bump stops on each printhead. It's the closest thing we non mhm users could do to replicate that system. I don't necessarily like putting the pallet jig on and off when needed but it's really not an ass whip like you'd think. Especially when considering the time savings you get by using a reg system. Uploading pics to photobucket now and will post them after we run a quick job.
