![]() ![]() 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. See the basic examples below.Raster engraving and vector engraving are the two types of engravings done using a laser engraving machine. However, vectors should be used at radical scale or for clarity of defined edges in simple shapes, such as logos and illustrations. If something requires more detail at an adequate scale, raster images are optimum. Raster images should be used for photos while vectors should be used for logos and illustrations. Because the scaling versatility, vectors are excellent for logos, illustrations, sign writing and embroidery. SVG, EPS, PDF and AI are common file formats for vector graphics. Often containing less detail than a raster image, a vector will retain appearance regardless of size and can be scaled infinitely.Īlthough you can include gradients and shadows in a vector, a true vector graphic is comprised of line art that is filled with colour. Vector images are made up of points, lines, and curves that are based upon mathematical equations, rather than pixels. For digital deliverables a 72dpi is sufficient whereas print requires a minimum of 300dpi. T hey cannot be scaled without sacrificing quality. The greater the dpi and dimensions, the higher the quality, and often the file size. Quality of a raster image is often dictated by the dpi (dots per inch) and the overall dimensions of the image. JPG, GIF and PNG are all examples of different types of raster files. This means raster images are capable of rendering complex, multi-coloured visuals, such as photographs. But, what do they actually mean and how are they different? Raster imagesĪ raster image (also known as bitmap) is made up of individual pixels and each of those pixels contributes to the overall image. So, raster vs vector? You may have heard of them and just nod politely when they are mentioned. ![]()
