However, laser engraving Vector is a bit faster than Raster because the laser moves from point to point instead of line by line. Vector laser engraving is very similar to Raster as the laser movement is bi-directional in this case as well. So, it is important that you get a good grip on professional tools like AutoCAD, Illustrator, or CorelDraw to design in Vector format. However, only a few software applications can generate the Vector or Scalable Vector Graphics (SVG). The major benefit of a Vector design is that it doesn’t lose quality or clarity even at maximum zoom. The path is formed by a mathematical formula that determines the color and shape of the path. Unlike Raster images, the Vector images are made from lines and curves, also known as paths. Moreover, both the X and Y axes move at different speeds, and the PPI (Pulses Per Inch) controls the density of the laser points.Usually, the laser movement is bi-directional, i.e., it moves in two directions only, so the process is a bit slower than a vector.The CNC router also controls the on/off action of the laser to ensure that every pixel is engraved in its correct position.When you press the print button, the laser will start moving back and forth to engrave the material line by line.The CNC controller of the laser engraver interprets every pixel and instructs the laser diode accordingly. When you insert the Raster image design in the software, it converts it into a computer-generated bitmap.The best definition of Raster laser engraving is that the laser moves back and forth while printing the design one line at a time, the same as an ink-jet printer. A bitmap is a mapping from some domain in computer graphics, i.e., binary, pixels, orbits. The raster images are better known as bitmap images. However, the resolution of the image remains constant, and the image will become distorted when you zoom beyond the safe limits. I know this is absolutley terrifying to think about but sometimes they actually do have the vector art and you are able to save a few dollars and avoid vector graphics conversion fees.Raster images are made up of millions of small pixels each pixel represents a portion of the image. This involves asking our clients if they have good vector art. At our studio we like to take the path of most resistance and least cost (wait what did he say?). Now that you know what the difference is, you may be asking yourself “Self, this is great and all but how do I get these people what they need to get my job done”? Great question. With vector graphics your image will look good on something as small as a business card and as large as a billboard or building sign. We don't ask for vector art because we are trying to look smarter than you or one up you, we are asking for it because we want your finished products to be incredibly awesome and high quality. If you are working with a printer or customizer that isn't asking your for or offering to create vector art then you are likely to be very disappointed with the final work product. When it comes to printing, engraving or reproducing artwork, vector art is the preferred method if you want great results. When you take a raster image and make it larger you will see that they often get blurry because raster graphics have a specific number of pixels. When look at a raster image in a graphics design program like CorelDraw, Adobe Illustrator or Inkscape and you zoom in, you will may begin to see lots of tiny little squares. Think of it kind of like coloring a crossword puzzle or a piece of graph paper (am I showing my age now -oh I feel old) to look like a picture of something. Raster images are effectively lots of colored pixels that come together to form an image. png (the one that can have the transparent background). The file extensions most commonly associated with raster images are. For most of us, this is what we are most familiar with. If you have ever taken a digital photo or downloaded a photo from the internet you may have created or downloaded a raster image. Each of these image types have very different purposes. There are raster graphics and vector graphics. Ultimately there are two types of graphics files that exist.
