photocom

Photocom is a type of photographic printing process that utilizes a photoconductive material to create images. This process is often used for printing large-format images, such as posters, billboards, and architectural signage. The photocom process involves several key steps:

First, a photoconductive material, typically a polymer or a resin, is coated onto a substrate, such as aluminum or plastic. This material becomes conductive when exposed to light, allowing it to be selectively exposed and developed.

Next, the image to be printed is transferred onto the photoconductive material using a light source, such as a laser or an LED. The light exposes the photoconductive material, creating a latent image.

The exposed material is then developed using a chemical developer, which removes the unexposed areas of the photoconductive material. This step creates a relief image on the substrate.

Finally, the image is transferred to the final printing material, such as ink or paint, using a printing press. The photoconductive material acts as a mask, allowing the ink or paint to be applied only to the exposed areas.

Photocom printing is known for its high resolution and durability, making it a popular choice for large-format printing applications. However, it can be more expensive and time-consuming than other printing processes, such as offset or digital printing.
