A digital image is a rectangle made up of many small squares of color called pixels. The number of
pixels across the width and height of the image is called the resolution. An image with 640 pixels
across the width and 480 pixels high has a resolution of 640x480. The more pixels in the image file,
the higher the resolution. The larger the file resolution, the fewer images that will fit on your camera
memory card. Commonly the size of a digital camera image is proportionate to a 4x5.3 not a 4x6.
We can make any size of prints from almost any image resolution. But the print quality may not be
acceptable when we make too large of prints from smaller image files. Please refer to the tables
below to see if your image sizes are big enough for the print size.
Resolution Table
The table below shows you the recommended print resolutions for different print sizes from your digital
camera (72 dpi). These are only guidelines and there are always other factors which can affect the
quality of your photos. Any print size above the "Some Pixelation Will Occur" field will have extreme
pixelation. TIP: When taking photos, always set your digital camera to the highest resolution possible.
This will help to ensure that your prints will look nice. Also indoors always use a flash.
Scanning Images
The table below shows you what resolution you need to scan your picture and quality output of your
print. The following equation can serve as a guide to help you determine the quality you may expect.
Our digital printers, Frontier 370 and Noritsu 3212, print high quality laser sharp at 300 dpi. Photos are
much sharper than any inkjet printer can print.
Find your print size: [resolution]/300 dpi = print size in inches.
example: a 1200x1800 resolution image will give you a high quality 4x6 print.
1200/300 = 4 inches and 1800/300 = 6 inches
If you have a 4x6 print and want to make an 8x12 print, you must scan the 4x6 print at a much higher
resolution ( at 600) in order to get a high quality print. Now any alteration can be made to the image
digitally. Try not to compress your image too much when saving. Tiff files are uncompressed. JPEG
files have different levels of compression. We can also print any custom print size.

Our Frontier print sizes are set slightly above 300 dpi:
size - pixels
3.5x5 - 1050x1524
4x5.4 - 1228x1654
4x6 - 1228x1818
5x7 - 1524x2138
8x10 - 2436x3036
8x12 - 2434x3638
10x15 - 3036x4536
*The Frontier prints full bleed. Using the Frontier print sizes when cropping in Photoshop will give you
more of the image. You will only lose up to 1/16th on an inch all the way around. Cropping to a standard
size in Photoshop (like 4x6) you will lose up to 1/8th of an inch.
This chart will roughly give you an estimate number of images you can take on your digital media card.
NOTE: This chart only goes to 1 GB. Multiply that number by the size of your card.
