What are Gobos?
A gobo is a physical stencil or template that is placed in front of a lighting source to shape or project a specific pattern or image onto a surface. The term "gobo" is an abbreviation for "go between" or "goes before optics," reflecting its purpose of being inserted between the light source and the area to be illuminated. Gobos are predominantly used in the entertainment industry, including corporate events, concerts, theaters, and social events like weddings and parties, to create visually captivating environments.
The history of gobos dates back to the late 1800s when theater lighting designers began using metal sheets with cut-out patterns to create diverse lighting effects on stage. These early gobos were primarily made from steel or brass, and the patterns were manually cut by hand. With advancements in technology, the process of creating gobos has evolved significantly. Modern gobos can be made from a variety of materials, including glass, metal, and even plastic, with intricate patterns and designs etched or printed onto them using advanced computerized techniques.
Gobos can be utilized in various ways to enhance corporate and social events. Here are some of the potential applications and benefits:
1. Branding and logos: For corporate events, gobos can be custom-made with company logos, slogans, or brand images. These gobos can be projected onto walls, floors, or ceilings, effectively promoting brand awareness and reinforcing corporate identity.
2. Decorative lighting: Gobos can create stunning visuals by projecting patterns, such as stars, geometric shapes, or floral designs, onto surfaces, adding a touch of elegance and ambiance to the event space. This can be particularly useful in transforming mundane venues into captivating settings.
3. Mood and theme enhancement: Gobos can be used to enhance the theme or mood of an event. For example, a winter-themed gala can feature gobos projecting snowflakes, icicles, or frosty patterns, creating a wintry atmosphere (We did this for a Frozen themed birthday party - Check it out in the gallery at the bottom of the page!). Similarly, gobos can be used to evoke specific emotions or themes like romance, celebration, or adventure, depending on the event's requirements.
4. Stage and scenic projection: In both corporate and social events, gobos are extensively used for stage lighting. They can help create scenic backgrounds, simulate environments, or add depth to the stage by projecting images of landscapes, buildings, or architectural elements.
5. Dynamic lighting effects: Gobos can be used in conjunction with moving lights or intelligent lighting systems to create dynamic and interactive lighting effects. By adding motion and changing patterns, gobos can create a sense of energy, excitement, or drama, enhancing the overall visual experience of an event.
6. Brand activations and product launches: Gobos can be utilized creatively during product launches or brand activations by projecting images or animations related to the product or brand. This technique can captivate the audience, draw attention to specific areas, and generate interest in the showcased products or services.
Overall, gobos are a valuable tool for event designers and lighting professionals to transform event spaces, convey specific messages, and create engaging and memorable experiences for both corporate and social events.

Transparency Gobos
Transparency gobos, also known as "glass gobos" or "color gobos," are a type of gobo made from glass rather than metal, plastic, or other materials. They are created by allowing light to pass through colored or transparent areas of the glass, creating vibrant and detailed projected images.
Unlike traditional metal gobos that rely on opaque or semi-opaque materials to block or shape light, transparency gobos work by allowing light to pass through specific areas of the glass while blocking it in others. The colored or transparent portions of the glass allow light to project the desired pattern or image onto a surface, while the rest of the glass blocks the light, preventing unwanted spillage or blurring.
The use of glass in transparency gobos allows for intricate designs, finer details, and sharper edges, resulting in high-quality projected images. Glass gobos are created through a process of etching or printing the desired design onto a glass slide. The glass can be transparent or tinted in various colors, offering a wide range of visual possibilities.
Transparency gobos have become increasingly popular in both corporate and social events due to their versatility and aesthetic appeal. Here are some ways in which transparency gobos can enhance events:
1. Customization: Transparency gobos can be highly customized, allowing for the projection of company logos, images, patterns, or text. This flexibility enables event organizers to create a personalized and branded experience that aligns with the event's objectives.
2. High-resolution projections: Glass gobos provide exceptional image clarity and sharpness, making them ideal for projecting complex graphics, fine details, or high-resolution images onto surfaces. This enhances the visual impact and overall quality of the event.
3. Vibrant colors: Transparency gobos allow for the use of vibrant, bold, and saturated colors in the projected images. This can significantly enhance the atmosphere of an event, evoking emotions, and creating a visually appealing environment.
4. Multi-layered effects: By layering multiple transparency gobos, it is possible to create dynamic and multi-dimensional effects. The blending of different colors or patterns can add depth and visual interest to the projected image, creating a captivating and immersive experience.
5. Projected scenery and textures: Transparency gobos can simulate scenic elements and textures, such as brick walls, foliage, or water ripples, on plain surfaces. This technique can enhance the overall ambiance of the event and create unique environments without the need for physical scenery.
6. Animated effects: Transparency gobos can be combined with moving lights and technology to create animated effects. By using rotation or movement, the projected image can appear to be in motion, adding a dynamic and engaging element to the event.
Transparency gobos offer limitless opportunities for event designers to create visually striking and immersive experiences for corporate and social events. By leveraging their customization, high-resolution capabilities, vibrant colors, and dynamic effects, transparency gobos can transform event spaces and captivate audiences.

How to make one
Step 1: The design
To create a transparency gobo, you must first begin with the design. In VECTR, create a canvas that is 2000x2000 pixels and add a circle that is equal to the width and height of the page. Your file should look something like this:
To create a transparency gobo, you must first begin with the design. In VECTR, create a canvas that is 2000x2000 pixels and add a circle that is equal to the width and height of the page. Your file should look something like this:
Next, add a second concentric circle in red about 70% of the original's size, and a third concentric circle in green about 90% of that. Ultimately, you should have something that looks like the following:
The red line is your bleed line, and the green is your safe line. Due to the curvature of the lens on an ellipsoidal light, the closer to the edges you get, the blurrier they will be when projected. In order to keep images as crisp and clear as possible, best practice is to keep integral elements such as text within the green area, while secondary elements can extend to the red, and tertiary to the edge. notice how in the example below, the text is centered within the green, the geometric backer extends slightly beyond, and the only element passing the red is the red gradient filler:
Once satisified with your design, hide the bleed and safe lines in the layer tab and export as a PNG file (we want all alpha layers to export). Then, load the file into a word document to size. Kalamazoo Gobos should be at 2" while Arcadia Ballroom should be at 3" Use the integrated ruler as a guide.
Once sized, load a sheet of transparency film into the printer and print your gobo. Be sure that the printer is set to it's maximum quality of 1,200 DPI so as to ensure as crisp an image as possible. After printing is complete, cut the gobo out using scissors. It is recommended that the general shape of the cut should reflect something like what the blue line depicts in the image below, as this will help the image to best fit in the gobo frame.
Once cut, the gobo can be loaded into the frame and installed into the fixture. To install a gobo into an ellipsoidal fixture, follow these steps:
1. Locate the gobo slot or holder on the fixture. In most cases, it is located at the front of the fixture, behind the lens.
2. Carefully open the gobo slot or holder. It may be a hinged door or an attached frame that can be pulled out.
3. Take the gobo, which is a small metal or glass plate with a design or pattern cut into it, and insert it into the gobo slot or holder.
4. Ensure that the gobo is inserted with the desired design facing the correct direction. The orientation is important because the light projected through the fixture will be flipped and the pattern projected will be the reverse of the gobo design.
5. Close the gobo slot or holder securely, ensuring it is properly aligned and latched.
The orientation of the gobo is crucial due to the design being projected by the light fixture. The orientation will determine the correct positioning and orientation of the patterns and designs being projected. If the gobo is installed upside-down or reversed, the projected pattern will not appear correctly, and the intended image or effect will be distorted.
For example, if the gobo has text on it, it needs to be installed in a way that the text is readable and not flipped. Similarly, if the gobo has a specific image or logo, it needs to be installed in the correct orientation to ensure the image appears as intended.
