ok so i tried 2x's to set up a screen and it didnt work out, what iam doing is making the image filled black, the image below, and then i take my transparency paper print it out,
i use speedball emulsion, i mix in a liquid measureing cup, 1 cup emulsion, and 1/4 cup sanzitzer (spelling)
and i mix that until its a brownish blue, i let the emulsion dry but the emulsion washed out while spraing out the image with water, and also the black ink that was on the transparency transfered to the screen is this suppose to happen? and then when i went to try n put a shirt through, i got an outline of the letters, not the letters filled with red, help please

Reason: picture
if you are having a problem with emulsion washing out it id probably one of 2 things: eaither you are under expoing it or, your screens are not getting completly dry. it doesn't matter how long you let the screens dry if your humdity is above 40% you will have problems.
the transparency seems not too bad, i means its not extremely dark, and you can see link little ink dots darker then others in the ink, but other than that its not really that bad
You have a few problems. There are many things missing from your post as to your mesh count, your tension, the type of ink that you are using and well... a ton of other information that would make it much easier to find a solution, but...
Your film positive may not have been set by the printer. Oftentimes ink from some printers, like an ink jet, will not properly set when printed to transparencies. They also may not be waterproof and if not, may not work well when placed against the emulsion which has moisture in it (no matter how dry it feels).
The emulsion may not have been coated correctly, was probably not fully hardened (polymerized) in this instance, and then not allowed to dry fully before printing.
These are only guesses based on what you have stated, but seem to be accurate. Give us more information.

Hey Bill,
I have not personally experienced this (yet), but I do know that it does happen. Would it be safe to place an additional transparency (blank film) between your film positive and the screen, or do you think this would just cause other problems?
Anyone else have input, other than just buying waterproof film.

I would not advise this practice. This can cause registration issues on press. You want the image as close to the emulsion/mesh as possible when burning. If there is space between the image and screen your burn will differ slightly from the actual art on the film. Undercutting during the burn process.
Screen rooms actually used this process back in the old days for choking/trapping when using stat cameras and dark rooms to create plates.
I will be using Union Ink, and The mesh count i will be using is 110, and i have a laser printer, the ink comes out all hot and dried, iam using a Kyoceral FS 1700 printer

The placing of an extra sheet of transparency will have no effect on press registration. If it is a one color image, this is a no brainer. If you are working with a multicolor image and each image had the extra transparency, they would all the same and thus no registration problems would occur.
If you are using a point light source with thick lines and large bold graphics the extra transparency will make little difference in the edge resolution. However, the finer the lines the more problems you will incur.
I have been a screenprinter since 1945, so I am qualified to speak about the "old days" of screenprinting. Well...at least the middle ages. No, we did not use this technique in the screenroom. We did use it in the camera room to make intermediate film positives and negatives, but never on screens. Even in the "old days" we used more common sense that one might think.
