In a vector image, only the outline or border is created through the fine lines and curves. After joining the dots with lines and curves, you have an image. It is quite similar to the Join the Dots activity that kids do at school. There are anchor points on the image, and these points are joined together with the help of a line or curve. There are no pixels or square boxes even if you magnify the image. What is Vector Engraving? 1) What is a Vector Image?Ī vector image on the other hand is a pixel-independent image. Due to the line-by-line operation of the machine, the engraving is quite bold and visible. The machine works like an inkjet printer. It follows the same pattern of pixels and engraves the image over the object. When raster engraving is done using a raster image, the laser engraver works line by line and point by point. These are created with the help of pixels. The common file formats that you see, such as JPG, PNG, TIFF, and BMP, are raster images. You can obtain such images from digital cameras. Raster engraving is done using a raster image or graphics. But the increase in the number of pixels also increases the size of the image. The higher the pixels, the better the quality. The quality of the raster image depends on the number of pixels. There won’t be any space left on the image and all boxes will be connected with adjacent boxes to create the image. After completing all the dots, the image is completely printed. It prints all the dots in their original color. If you look closely at the print, you will realize that the printer has worked line by line. When you use an inkjet printer, it also prints the image on a paper pixel by pixel. A raster image is made of tiny pixels, which is why it is also referred to as a pixel-dependent image. When you zoom in on an image, you see small boxes or squares, which are called pixels. You might have zoomed in on images many times. After that, you will be able to understand how raster engraving works. Before diving into raster engraving, it is better to understand what a raster image is.
