Creating high-resolution images is simple if you have the right tools. Whether you use a digital camera, scanner or piece of computer software will dictate how high the resolution can be.

Consult the user manual for your camera to determine how to change your image quality to the maximum setting. This will take up more space on your memory card but ensure that you are creating the highest quality pictures possible.

Open your scanner software on your computer. There should be a setting called either "Quality" or "Resolution." Sometimes you only have the options for high, medium or low quality, while other times you can change the dpi to a number value. You should also have the option to change the color. If you are scanning text or a simple black-and-white line drawing, your dpi should be set to 1,200, and your color settings should be set at 1-bit (sometimes called bitmap) or black and white. If you are scanning an image that is several different shades of black, your color settings should be grayscale, and dpi should be a minimum of 600. When doing full color, set your colors to as many as you can (sometimes going up to 8 million, but CMYK is fine, too), and resolution should be a minimum of 300. This will ensure that you get the best quality. Setting your resolution any higher than that can create strange images.

Use a professional graphics program like Adobe Photoshop. Create a new file. When the Image dialog box pops up, make sure your values under Resolution are set to 300 pixels per inch or higher.

Change your print settings to get the highest quality output. Most home ink-jet printers cannot print more than 600 to 1,200 dpi. Hit the "Print" button, and go into your settings (sometimes called "Options" or "Advanced Settings"). Look for an option for print or image quality and change it to "Best." Check all your other options to see if you can give your print a numerical value for resolution. If you can, change this to 600 or 1,200 dpi, which is the highest possible.

Tips & Warnings

  • * You must change the resolution when the image is created. If you increase the resolution of an image that was low-resolution to begin with, the quality will not change.
