Review: Newbies Take Note - Use Online Support with Speedball; Loads of Fun with Patience - This emulsion works very well. Keep in mind we are very inexperienced screen printers and are just now navigating our way around. We used Speedball's website for instructions on printing (there are several ways to print). Following their online guide really helped. The first run, we applied too much emulsion and it created dots or drips from pooling at certain places on the screen. Lesson learned, we moved on and applied it much thinner the next time and that eliminated the drips.Yes, they tell you this, but as a newbie, you think you're painting on enough but there is such thing as too much. We refrigerated the solution as instructed and it has performed well being preserved. Another hard lesson we learned is that screen cleaner is NOT the same thing as emulsion remover. We cleaned for well over an hour with just screen cleaner and it does not break up used/exposed emulsion. You need an emulsion remover to tackle this stuff. Though we did end up trying some home remedies to clean off the emulsion (lemon or citrus cleaners, hard spray (without a pressure washer) and scrubbing. We saved the screen for another use without purchasing the emulsion remover, but we will add that to our arsenal. This is a fun, albeit learning process. I now hold higher admiration for those screen printing companies that put a lot of work and apply the right methods to making a t-shirt. This is fun, but if you plan more than stencil screen prints, there is an art to it. Hopefully, we'll become artists with a little practice and patience.
Review: This is a winner. - Been using this since i started screen printing at home. It is always on point no issues and burn time is low about 6 to 7 mins @ 500 watt buld. Always comes out perfect. I tried another product and had nothing but headaches. I will not stray from the path again. Awesome product for home use.

## Questions & Answers

**Q: How much sensitizer do you need for this amount of emulsion?**
A: I believe it's the 2 oz biytle

**Q: Can you use UV black with this emolsion???   And what’s the best recommended light source??**
A: I use a 500W Halogen lamp mounted 15" above for 5-10 min depending on design, thickness of coat, etc. I've also used a black light for 6-8 minutes at same height with good results. This emulsion works either way, but is very light sensitive. So must be kept in a light safe area until complete. This is the best product I've used for ease of use.

**Q: Can the speed diazo photo emulsion be used on paper for regular photographs**
A: No, it is specific for filling screen printing screens. Film photographs require a different set of chemicals.

**Q: Hi, how long i have to wait after mixing to use it ?**
A: First wait at least 30 minutes to get rid of any bubbles, expose the emulsion to as little light as possible. The sensitized emulsion can be stored (according to the bottle) in a cool, dark place for about 8 weeks at room temperature (70F), or four months in the refrigerator.
