Plastic gobos?

Years ago there was a product with which you could make your own gobo on an ink jet printer and drop them into a sp holder for the incandescent S4. I believe that there was a fan to keep the gobos from turning into gooey slag in the bottom of the fixture.

My question is this: can we print out own gobos for the S4 LED V2 ? It's got a pretty low operating temperature. That plastic film thing that they ship with the fixtures doesn't melt.

Hi Dave,

why yes - with S4 LED / LED2 , you can print out your own gobos on normal Overhead projector plastic Sheets, and

cut them out and put them in your S4 LED / LED2 Fixtures as gobos.

yep, do it all the time. transparency that survives xeroxing or a laser printer should be safe.

Thanks for the quick response. It kinda seemed likely.

Just curious, but can the plastic gobos be used with the new Source 4WRD when it is on a normal Source 4 fixture?

I've used transparency film with S4 LEDs of both vintages and they'll work for quite a while, especially with the source in a color other than white, and especially at intensities below full. After a long time at full, the transparency film will start to warp and droop. This isn't usually a problem, since you can just print a new one.

I imagine the gate temperature when using the 4ward LED retrofit cap is roughly in the same ballpark as a S4 LED.

Rosco still makes the iPro unit that the OP mentioned. I've never had any trouble with an iPro for long periods of time. You can buy their special high-res transparency film too. That stuff is great.
