Hi. I'm new to screen printing so I could use a little help from anyone who has experience with it.

1) I'm going to be making quite a few small screens that I'll need to re-use at a later time. My question is, should I build a separate frame for each one and store the screens on the frames or should I de-mount the screens and store them without a frame and re-mount them only when I need them again?

2) Has anyone here ever used FastPos Inkjet film from U.S. Screen Printing? It's expensive and I'm wondering if plain old sheet acetate will be satisfactory in its place.

I'd appreciate any help you can give me. Thanks.

- Ray

P.S. In case you're wondering, I'll be making bumper stickers.

I would store with the screen attached to the frame. Any other way is asking for trouble. The main thing you want to do is to maintain tension so you put down a consistant film of ink. The best thing is to buy a couple of roller frames, expose, print and reclaim, using your films over and over. Tight screens also prevent blurred edges along the edges of your image.

Doug is correct. Along with keeping the tension of the screen, taking them off can screw up your registration also when doing multi-color work.

Thanks, sassybird. This brings up another question: Would keeping the screen stretched on the frame result in damage to it in the long run?

If you are doing single color imaging, you could hold on to the screen for quite some time. I used to do t-shirts and would hold regular customers screens for six months without any discernable degradation. Screen material (organdy, polyester, nylon and silk) have a tendency to loose tension with time. It has to do with the chemistry of the materials, and I don't remember the physics. Your local screenprint supply company could give you a lot of information on that. Call and ask for their screenprint specialist. I would tend to shy away from the art store in this area, unless in your interviews with the staff someone shows a genuine interest in printing and printmaking. Most of the staff has too many products to deal with and too many techniques to stay abreast of to be a lot of help in every area. Good luck

For the question about the acetate:

If you are using it to print from an inkjet printer, then you will need special acetate. It has a sticky film on one side so that the printer ink can stick to it. If you are doing small sizes you can jsut go to your local office supply store and pick up a pack of sheets.

If you need a large size, try a college bookstore. Mine sells the large sheets with the film on the back. I didn't try them but I don't remember people in my class complaining about the price, so it's probably not all that bad. I don't think the brand will really matter.

If you are just using it for registration then there's no reason not to use plain acetate or mylar, but I don't think that was what you were asking.
