Create your images at 200 to 300 dpi at final output size. If your image has very fine detail and is to be printed on canvas or photobase papers, create the file at 350 dpi to maintain sharpness and detail.
If you have an existing file and you cannot recreate your image at a high resolution, DO NOT simply resize and resample it with a graphics program to achieve the higher resolution. For best results, you must create your image at the proper dpi.
However if you must enlarge your file, we suggest using a program called Genuine Fractals, www.genuinefractals.com.
