Why Vacuum Blasting Is the Best Choice for Granite Engraving

The vacuum blasting technology developed by systeco offers numerous advantages for creating photo engravings and engravings on granite. Unlike traditional pressure blasting, there’s no need to move the workpiece into a blasting cabinet – engraving is done directly on-site, regardless of the surface size.

Another major benefit: the stencil film remains stable even during long and intensive use, making it possible to complete large-scale engravings without interruption.

While pressure blasting requires extreme precision to avoid damage from incorrect angles or excessive pressure, vacuum blasting ensures consistently clean and accurate results. It allows for high-detail engraving – even without specialized skills or prior experience.

With systeco, you're choosing an innovative and user-friendly method for granite engraving that combines efficiency, quality, and durability.

Creating a photo engraving on granite requires precision, expertise, and the right technology. With systeco's vacuum blasting system, highly detailed engravings can be permanently applied to stone surfaces. The foundation of every engraving is the stencil film, which defines the image.

Step 1: Preparing the Image

The desired image is converted into a black-and-white graphic using a design program (e.g. Photoshop). Since true grayscale tones cannot be engraved, contrast is created through the dot density of a halftone pattern. The image is then inverted to a negative and printed onto a transparent film.

Step 2: Producing the Stencil Film

The printed film is placed onto a photosensitive blasting film and exposed under UV light. After several seconds of exposure, the film is rinsed with water and dried. The exposed areas of the material are dissolved, allowing these parts to be blasted later. For durability, the finished stencil is coated with protective layers.

Step 3: Applying the Film

Before engraving begins, the protective layer on the adhesive side is removed. The stone surface is slightly moistened, and the film is carefully positioned. A rubber roller is used to press the film onto the stone, then the upper protective layer is removed. All areas not to be engraved are thoroughly masked off.

Step 4: Engraving with White Corundum

Now the actual blasting process begins using fine white corundum as the abrasive. Blasting continues until the desired engraving depth is achieved. Once complete, the film is removed, and the design can be optionally color-filled to enhance contrast.

Many stonemasons have their stencil films created professionally, as specialized equipment is required. However, with systeco’s vacuum blasting technology, the entire process becomes easier, more efficient, and delivers precise and durable results for any photo engraving on granite.

Photo Engravings on Granite – Now Easier Than Ever with Vacuum Blasting

Photo engravings on granite are offered by many businesses. Traditionally, stonemasons have included photo engravings as part of their services. However, more and more companies are now specializing exclusively in creating photo engravings on granite slabs.

Thanks to vacuum blasting technology from systeco, creating photo engravings has become particularly simple. The blasting machine is easy to operate, and the stencil film remains intact throughout the entire process – even during extended blasting sessions. This makes systeco’s solution ideal for detailed, durable, and professional granite engravings.

The QR code is a method of writing down information in such a way that it can be found and read by machine particularly quickly. We are encountering such squares more and more frequently. With the so-called QR code scanner of the smartphone, the respective information is read in easily, quickly and without errors and the user is taken directly to the corresponding page on the internet.

This procedure is increasingly used by bereaved families to present the life and work of a deceased person more comprehensively. The QR code to the corresponding memorial page on the internet is displayed on the gravestone and visitors to the grave can scan it and receive as much information in the form of texts, pictures or films about the deceased as no gravestone, no matter how huge, could present.

In order to place the QR code on the gravestone, the stone has to be brought into the blasting cabin using conventional blasting methods. This is time-consuming and very inconvenient. With the vacuum blasting process from systeco, the QR code can be blasted onto the stone directly on site. The amount of work is minimal.
