The inner part of the image remains empty, unlike raster images. 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?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 machine 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. If you look closely at the print, you will realize that the printer has worked line by line.
After completing all the dots, the image is completely printed. It prints all the dots in their original color. 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. What is Raster Engraving?īefore diving into raster engraving, it is better to understand what a raster image is. We will try to explain every aspect that a laser machine beginner should know. We will also share which engraving is better in different scenarios and how you can do these engravings on materials. In this article, we will discuss raster engraving and vector engraving in detail. Sometimes, it is difficult to choose the right engraving for the purpose, so it is better to have in-depth knowledge of both. If you do the wrong type of engraving on a material, the result might not look good.įor beginners, it is necessary to understand these two types of engraving. You might consider raster engraving in one case and vector engraving in another it depends on the requirements. Therefore, the user must decide which one is suitable. Both types of engravings have their distinct appearance, features, pros & cons, and limitations. Raster engraving and vector engraving are the two types of engravings done using a laser engraving machine.
