Pre-press is an all important step in the print production process. It can be quite a headache if you don’t start with the correct file type for your graphic.
Vector Graphics are required for most print jobs because that can be manipulated and scaled without losing resolution or image quality.
Unlike JPEGs, GIFs, and BMP images, vector graphics are not made up of a grid of pixels. Instead, vector graphics are comprised of paths, which are defined by a start and end point, along with other points, curves, and angles along the way.
Because vector-based images are not made up of a specific number of dots, they can be scaled to a larger size and not lose any image quality. If you blow up a raster graphic, it will look blocky, or “pixelated.”
Most images you see on your computer screen are raster graphics. Pictures found on the Web and photos you import from your digital camera are raster graphics.
JPEG and GIF are the most common compressed image formats on the Web, but several other types of image compression are available.
Raster graphics can typically be scaled down with no loss of quality, but enlarging a bitmap image causes it to look blocky and “pixelated.” For this reason, vector graphics are often used for certain images, such as company logos, which need to be scaled to different sizes.
When you blow up a vector graphic, the edges of each object within the graphic stay smooth and clean.
This makes vector graphics ideal for logos, which can be small enough to appear on a business card, but can also be scaled to fill a billboard.
Vector graphics can come in the following file formats: PDF, .ai, .eps
