Please read the following requirements for submitting a custom order:

  1. Artwork Requirements (minimum image resolution of 150 dpi)

*Custom Steel Gobo Artwork Disclaimer: We strive to replicate the original artwork received as much as possible when rendering it as a custom gobo. Please note that metal tabbing is almost always necessary for this type of gobo, and that smaller sized gobos with detailed art or several characters may need to be changed.

  1. Gobo Size and/or Fixture Type
    Rosco can manufacture custom steel gobos to fit virtually any light fixture available. The fixture you use will determine the size of the gobo you need. If you know the gobo size (B-size, M-size, etc) your fixture requires, then that’s all we need. If you don’t know the actual gobo size, many times the fixture manufacturer will provide its gobo requirements, including the gobo’s outer diameter (O.D.) and image area (I.A.). To be sure you get a gobo that fits your fixture, it's always best to provide the make and model of the lighting instrument you are using when ordering.

  2. Need by date must be a minimum of 2 days after order date. Minimum need by date requires overnight shipping to be selected at checkout. 

Product Description

Custom steel gobos are the most inexpensive way to project an image. Whether you need to project a monogram of the bride and groom at a wedding, a specific breakup pattern onto your set, or a company logo at a corporate event – custom steel gobos can sculpt the light into the letters and patterns your design needs. With facilities in both the US and Europe, Rosco is the largest manufacturer of gobos in the world.  Rosco's two art departments ensure nearly 24-hour coverage so that someone is almost always available to work on your gobo design.

Wet Etching for Clean Vertical Cuts:

Rosco utilizes a double-sided, wet etch gobo process using thin (5 mil) stainless steel. This process yields a durable gobo with exceptional image quality. Because we etch on both sides, a straight line is cut through the steel, versus a tapered/angled line from one side. Wet etching remains the most precise technique for creating details and fine lines in both glass and steel gobos. When it comes to gobos, tiny imperfections on the surface turn into large issues when they’re projected. Our precise, vertical cuts produce a cleaner projection with less “feathering” of the image than other etching techniques.

Long-Lasting Durability:

It may seem counter-intuitive, but not only does producing our steel gobos on thin (5 mil) steel yield a better a projected image, it also produces a gobo that retains less heat than thicker steel gobos. The more heat a gobo retains, the faster it will deteriorate in hot fixtures; especially in designs with fine details. This means that a thinner steel gobo is actually a stronger steel gobo.
