Importance Of Resolution

Importance Of Resolution When You Convert To Vector

In order to work on a raster image using any CAD program, it is important to first convert raster to vector. Only after you convert raster to vector image, you will be able to make any changes and alter the raster drawing. However, not all raster images can be converted into perfect vector images because of resolution related issues. The resolution is the term used to refer to the total number of pixels present per inch in the raster image. The “dots per inch”, commonly known as dpi, refers to the resolution of the image. For example, if the image has 400 pixels per inch, the resolution is said to be 400 dpi. When you convert raster to vector, the resolution of the raster image plays a very important role since the definition of the shape in the scanned image is dependent on it. The higher the resolution of the raster image, more defined the shape is when you convert to vector. In a high resolution image, the pixel size is smaller since the number of pixels per inch is more. This translates into smoother curves when scanned. If the raster image is of a lower resolution, the shape gets distorted when you convert raster to vector. In order to convert to vector, you have to first increase the resolution of the raster image.

Is it possible to increase the resolution after vectorization?
You have to choose the right resolution before you convert raster to vector. Once the scan is complete, it is not possible to increase the resolution. Increasing the resolution of the scanned vector image will only lead to the type of results generated by Photoshop. The only solution in such situations is to start the process all over again using higher resolution for smoother lines and curves.

Perfect resolution to convert raster to vector
The “right” resolution is very subjective in nature and is dependent on raster image that you would like to convert to vector. If the raster image has a lot of intricate details that need to be replicated to perfection in the vector image, you have to ensure the resolution is high. Most people prefer a resolution in the range of 200dpi to 500 dpi to convert technical raster images to vector. However, if you want to convert logos and other intricate artwork to vector images, you have to ensure a resolution in the range of 700dpi to 1250dpi and more. If you want to make sure you have the right resolution after you convert to vector, zoom in on the vector image to see if the lines and curves are well defined. If the curves and lines are as close to the raster image as possible and are comfortable for you to work on, you have chosen the right resolution.
