![]() Lines within the image will either be engraved or cut based on the line thickness. Any filled area, such as the tan or grey portions of the image, will be engraved with the laser. While raster images can only be engraved, vector artwork can be both engraved and cut with the laser. When we convert the image to a bitmap, which is a raster image file format, we can see all of the dots making up the image when we zoom in. If this deer head image was a raster image, it would look like a series of different dots. Here we have changed the color of this part of the image to white. We can select each different line and fill within the graphic and make changes. This is one of the big benefits of working with vector artwork, because it means you can expand the image as much as you want and never lose engraving quality. When you zoom in, you won’t find dots that are used to create the lines and colors in the image, but only continuous lines created with continuous fills. Let’s zoom in to this second deer image to see how vector artwork looks close up. A vector image is an image created with a series of lines and shapes filled with a solid color instead of pixels. Now, let’s look at a vector image and how it works with the laser. ![]() As long as there are pixels that make up your image, you will be engraving it with the laser. The most important thing to remember is that raster artwork is always going to engrave on the laser, it is never used for cutting. While raster images produce great engraving results, if you increase the size of your image, each dot expands and your engraving quality decreases. The smaller these pixels are, the higher the quality of the image, and the better the engraving will turn out on the laser. When viewed up close, there are thousands of colored pixels that make up the image. It looks like a highly detailed picture, but is actually made up of thousands of tiny dots, or pixels. This deer image is an excellent example of a raster image. A raster image is an arrangement of cells, called pixels, which form an image when displayed on screen. Let’s begin by talking about raster images.
