GUIDE TO IMAGE RESOLUTION
RESOLUTION refers to the number
of colored dots or pixels that make up an image. It is commonly
expressed in dpi or dots per inch.
RESOLUTION RULES-OF-THUMB:
-
The higher the dpi, the greater
the resolution, the better the image quality. Higher resolution
images create larger file sizes.
-
Image resolution is directly
and inversely proportional to an image's physical size. When
you increase the resolution of an image, reduce its size.
-
When you enlarge (inches) an
image and lower the resolution (dpi) the image will print
poorly.
-
For printed images, the ideal
resolution is 300 dpi at the final printed
size.
Here is a chart to help you determine the proper
dimensions of your image at your desired print size and in the
recommended resolution of 300 dpi.

More Hepful Tips
-
Your screen resolution doesn't
accurately reflect your image resolution because monitor displays
usually have about 72 to 96 ppi. To view the print resolution
of your image, zoom in up to 300 - 400%.
-
When taking pictures from a
professional level digital camera
for your print project, it's best to set your camera to the
highest resolution L smooth jpg + RAW setting.
-
Four-Color Process Print uses
the CMYK swope 2 color mode. Convert RGB images to CMYK using
graphics editing software such as Adobe Photoshop.
-
Save and transmit your photo
images in a lossless file format such as tif LZ compression
or eps to maintain accuracy and quality.
- Save art files with bleed allowances and finish
crop marks and transmit art file as PDF (will reduce transmittal
file size).
