Vectorization

There are two main type of image files: Raster and Vector. Raster images are created with pixel-based programs or captured with a camera or scanner. They are more common in general such as jpg, gif, png, and are widely used on the web. Vector graphics are created with vector software and are common for images that will be applied onto a physical product. Also used in CAD, engineering, and 3D graphics. When using a raster program you paint an image and it's similar to dipping a brush in paint and painting. You can blend colors to soften the transition from one color to another. When using a vector program you draw the outline of shapes: and it's similar to creating an image with tiles of all different shapes and sizes. e.g. an eye shape, a nose shape, a lip shape. These shapes called objects display one single color each. A lot of images can be made with either raster or vector program and look exactly the same on both programs. Images with a subtle gradation of one col...

A lot of our vector drawings are for engravers who tell us they will use the vector file for relief engraving, laser engraving, sandblasting, etching, or cutting. I am guessing these are some of the few process left that require vector art. Although I have never actually used an engraving machine or tool, I have been preparing vector graphics since 2000 for many different purposes including engraving and sign cutting. Below is a recent engraving project The image engraved on this stone needs to be reproduced in vector format This is the vector drawing as per Engraver specifications Engraver work in progress Final engraved product See the project from beginning to end,  including errors and corrections that needed to be done before the vector drawing was appropriate for the particular process:  http://vector-conversions.com/engraving.html
