Printing Digital Photos
With a high quality image
file (determined when the photo is taken), digital images can be
successfully printed either on a home inkjet/laser printer or by a
photo lab. Images printed on home inkjet and laser printers usually
require less information than Digital Photographic Prints as shown
in the table below. A good quality 4x6 on a home printer could be
printed from a 135KB file. For true photographic quality output, a
300KB .JPG file is recommended for a 4x6 print.
Digital Camera Files:
Most digital camera images are proportionally sized as 4x5.4". To
avoid image loss and cropping, we recommend choosing this ratio/size
when printing.
File Format Recommendations
Follow these guidelines for optimum quality prints.
