What is a gobo?
Glass gobos are made from transparent glass with a partial mirror coating to block the light and produce "black" areas in the projected image. This eliminates any need for bridging, since the glass itself is the support, and allows more intricate images to be produced. Glass gobos can also include colored areas (much like stained glass windows), whether by multiple layers of dichroic glass (one for each color) glued on an aluminium or chrome coated black and white gobo, or by newer technologies that allow the thickness of the dichroic coating (and therefore the color) to be varied in a controlled way on a single piece of glass, making it possible to turn a color photo into a glass gobo.

Artwork quality for glass Gobos
We can accept artwork from nearly all sources. We strongly recommend sending EPS or Adobe Illustrator (AI) files. These formats retain artwork as line-art instead of pixel-based bitmap images like JPG, GIF or BMP. By using line-art instead of bitmap art, the shapes and text will remain extremely crisp with no pixilation when enlarged.
You can also send us photographic images. Please supply the highest resolution available for your artwork unless you supply line-art files. The desired resolution is 1200 dpi but lower resolutions will also work. However, if the resolution of the image is too low (a logo from a website for example) then it may look pixilated and the image will have to be redrawn. For an example of pixilation, see the examples below.
The maximum resolution that we need is 1200 DPI with dimensions of 60mm x 60mm. You can also send a 72 DPI jpg with the dimensions of 1000mm x 1000mm.

Which light is best for projections?
In this case darkness is our friend. Daylight and sunlight are disruptable influences. To make light visible in light is comparable to trying to see white drops in a white colour. You need contrast. Shadow, dark areas or cloudy skies provide some clarity for images but the clearest are achieved in total darkness and these can be projected over far greater distances.
What surface is the best for projection?
The best surface is a white one because it reflects the light better. But light coloured surfaces, pink, yellow, light blues and greens etc. are also passable alternatives. Mirrors and stainless steel surfaces should be avoided because they reflect the whole of the light. Goods on display in cases, on shelves or in shop windows can also be good surfaces for projection.
