Vectorization

We get a lot of requests to convert photos to vector format. One of the reasons is that some printer's guidelines state that in order to print good quality images in large format vector graphics are required. Maybe a little clarification is needed because vector graphics are drawings, so converting a photo to vector means making a drawing of the photo and that isn't necessarily what is needed or wanted. Most printers will accept vector AND high resolution; in this case, designs including photos can then be provided to printer using both vectors plus non-vector good quality photos. If the images you want printed in large format are: A. Photos Images that are captured with a camera need to be supplied in high resolution (large image*) format. Photos are not scalable so simply enlarging a small image will result in a poor quality large image. The photo must have been taken with a high quality setting on the camera, so that it will be the size needed for t...

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...

Manual vectorization with soft color blends Here is an example of a recent vectorization from photo to vector (raster to vector). This drawing was for screen printing and, for this particular project, it didn't have to be drawn using only vectors. In addition to drawing with vectors, some vector graphics programs also have tools that allow you to use pixel-based, raster (non-vector) elements such as soft color blends & shading/highlights. A graphic that is created with a vector drawing program but also includes pixel-based smooth color blends and soft shading is not a 100% vector graphic, or a true vector graphic; it contains both raster and vector elements. See Raster vs Vector Photographs are raster graphics made with pixels: a multitude of different color pixels create a realistic image. Vector graphics are drawings made with objects: lines and curves that create shapes. When a photo is vectorized, it means a drawing of the photo is being made and, i n mo...

The only thing I know about engraving is that the vector artwork needs to be created in black and white line-art, and depending on the size of the actual engraving, real small detail should be avoided. There is actually a lot of small detail on the image below and I was sure the engraver was going to reject it but the plaque must have been large enough to hold all the detail.  Some challenges may arise when changing a multi-color image to black and white LINEART (not black and white grayscale ). Elements in the graphic will no longer be defined by different color or shades of gray, they have to be black or white only and you will have to decide which elements are black and which elements are white. Using outlines instead of fills usually works to separate two objects of similar color. When images are on a color background, removing the background may make the overall feel of the image look different. After playing around with these ele...
