Vector vs. Raster
A vector graphic is an image that was created in illustrator. it does not rely on DPI. These graphics are points, lines, curves and shapes that are based on mathematical formulas allowing them to be reduced or enlarged to any size without causing them to lose resolution.
- Specific colors are defined
- Quality does not change regardless of size.
- Perfect file type for 1-3 color orders
Raster images are made up of tiny pixels, making them resolution dependent. Raster images are measured through DPI (dots per inch) an image that is 300 DPI but only 2 inches big, the DPI will lower significantly when enlarged to 18x24 inches for printing.
- Quality will decrease the more the image is increased.
- May incur artwork fees if used for 1-3 color orders.
- Text could become illegible on larger products
RASTER - PNG, JPG Files
VECTOR - Print ready files
