For the large majority of printing methods (pad printing, screen printing, engraving, etc), images need to be available in vectorized form.
Vectorized images can be easily manipulated, made bigger or smaller in size, without affecting their resolution. In comparison, raster graphics often become distorted when you alter their dimensions, losing their original clarity and quality. Click here for an example.
Furthermore, vector graphics can be very easily edited - colours within a vectorized image can be modified or changed, elements can be added to the image or taken away quickly and simply.
Existen dos formas de vectorizar imágenes:
A specialised designer, using specific tools, redraws the image by hand. The result is a vectorized copy of the original image with a fewer number of nodes.
The majority of modern CAD programs offer the facility of automatically tracing (vectorizing) images. The user specifies an image, as well as a series of parameters, and the program generates a vectorized copy of the original image. However, the quality of the end product depends heavily on the quality of the original image - in many cases, the lines and borders of the image do not appear smooth or even. Generally speaking, automatic vectorizations require a lot of subsequent editing in order to achieve a result similar to that of a manual vectorization.
