The resolution, commonly referred to as dpi or dots-per-inch, means the clarity of the image. The higher the dpi the clearer the picture. To achieve a crisp, clear image on the finished product, 300dpi images are required. Resolution is the most important factor in digital artwork. Resolution must be correct when the artwork is designed.
Resolution will decrease when an image is enlarged; conversely, resolution will increase when an image’s size is reduced. This is a process known as re-sampling, and it balances the size/dpi ratio proportionally.
We CAN NOT increase the resolution or detail of low resolution artwork.
