How much detail can you get in a steel gobo?
This answer of course mas many variables, such as size of gobo being used and font, not all are the same size.
The attached picture just a simple example of detail that is easily done in laser cut steel gobos.
Why there is no such thing as a standard size gobo?
People often say they would like to order or make a standard size gobo. The problem with this is statement is, that there is no standard size for gobos.
There are certainly some gobo sizes that are more popular than others, but there is no standard size in the Gobo world.
The reason is that each lighting instrument that projects gobos takes it’s own unique gobo size, and because sizes are different, some gobos can fit much more writing, or a larger design, than others can. There are over 75 different gobo sizes and each fixture takes it’s own unique gobo size. Gobo sizes are usually referred to with a corresponding letter, like A size, B size, M size, D size, or even Q size. If you do not know the name or the size of gobo you need, the two sizes that you will need are, the OD (outside diameter), and the IA (image area), the IA is where the design will be placed on the gobo. For example, A size gobos have a 100 mm OD, and a 75 mm IA, but the Q size gobo for the GoboMan projectors, has only a 22mm IA, and a 49 mm outside diameter, so obviously the A size will fit much more writing and a larger design than the Q size gobo. That said, you can still get up to 13 letters on a Q size gobo depending on the font used. You don’t want to try to get to much on a gobo because you can end up with tiny letters that don’t project a lot of light .
There are many websites online that provide lists of which lighting instruments take which gobo size and what the exact measurements are. There must also be a match between the gobo size and the correct sized gobo holder. This is also not a standard size. A good example of this is the ETC Source Four, which can take either a A size gobo holder or a B size gobo holder and also a glass pattern holder, so not all gobo holders are the same, or a standard size.
What is the difference between glass gobos and steel gobos?
We get many questions about the differences between Glass Gobos and Steel Gobos.
With a steel gobo, think of it as sort of like a stencil- The design is being cut through the metal, which would require tab support lines to keep the image intact- holding in the centers of letters, things like that. Steel gobos project white light or a single color by using a gel. Glass gobos employ a dichroic coating process on top of the glass, so they do not require support tabs, and can be muti-color. The cost of glass is almost 4 times as much as the cost of steel, so it’s important to take into consideration not only your personal aesthetic, but also your budget concerns.

What size gobo holder fits a ETC Source Four?
The truth is that the Regular ETC Source Four 575 watt and 750 watt units have a choice of three gobo holders available, and the ETC Source Four Jr. has two gobo holder options available.
The 575watt and the 750 watt units can either accept an A size gobo holder, or a B size gobo holder, or a glass gobo holder.
The ETC 575 watt Source Four Jr. takes an M size holder, or glass M size gobo holder.

How to sharpen your gobo image using a donut
A donut, is a thin metal or cardboard panel, similar in shape and appearance to a color frame, but with a small diameter hole intended to reduce off-axis rays of light being projected from a fixture.This increases sharpness of the light by reducing the effect of imperfect lenses. Donuts are designed to fit into the color frame holder directly outside the fixture, immediately in front of lens assembly. Because they are typically thin, doughnuts can often be placed in the same slot as a gel frame. Doughnuts are typically used in fixtures in order to sharpen the beam when a template is in place.
Used to increase the clarity of patterns and custom gobos by reducing halation therefore sharpening the projected image. The donut sharpens the definition of projected gobo images by blocking the unwanted light.

Where do I see Gobos
Gobo light and Gobo images are something very common these days, more specifically these nights.

These Gobos are physical templates placed in front of a lighting source or slotted inside it. They can be of any shape manipulating the shape of light; hence we can see the light or gobo of any shape. Actually, the word gobo is derived from ‘Go Between’ or ‘Goes Before Optics’ on account of its functions. These manipulations can be done using pieces of material with patterned holes, kinds of shapes, beautiful designs, names through which light passes, to block the rest part of the light.
These physical templates were originally used on film sets. They gradually been acclaimed for their appearance and have been used for various occasions to bedeck the surrounding. Gobo light and gobo images through metal gobo, which are generally projected in white colour,offer most elegant look.
