Introduction to Digital Pyrography

Let's begin with what digital pyrography is not.

It isn't traditional wood burning. In traditional wood burning the artist holds a heated pen on the media varying the speed and pressure of each stroke to heat it and produce a shade from light to dark. This form of pyrography requires delicate drawing skills requiring a lot of patience and practice to master.

It isn't laser engraving. You can take a photograph down to your local trophy shop and they will happily offer to transfer it onto a variety of objects suitable for commemorative gift giving. Their process is monochromatic. Each spot the laser touches receives the same amount of energy and this results in a very similar color change. Some of these places can simulate a greyscale image by use of the halftone technique. These look fine from a distance but the illusion breaks down the closer you get to the surface.

Here at Nova Pyrographics digital pyrography is the process of rendering a digital image at high resolution by heating each pixel for a very precise time. Each pixel is the same size so there is no halftone trickery. The resulting color range is much wider than the human eye can discern. In the darkest areas we do sometimes get a microscopic bit of char removal but this isn't intentional and so we're not engraving the image. Unlike traditional pyrography we operate over the entire surface of the media and this is where the magic happens. Our process never produces the same image twice because the grain of the material becomes part of the result. We anticipate this effect and choose media who's grain will compliment the image. Because we use high resolution our pixels are very small. This means our images can be appreciated from up close or across the room.
