Most images downloaded from a website were not designed for printing.
Website images are generally 72 - 96 ppi (dpi) and printed images should be at
ppi (dpi). Though 150 dpi is the minimum dots per inch you should aim for, the
is determined by the printing device. In the case of Pixart Prints, we recomend
setting your image
resolution to 300 ppi.
Digital Camera Images used in print
When using a digital camera, quality is oftern a major concern.
If you need good quality and you're using a mid to low range
digital camera, you're better off switching to a film camera
and then scanning
the negative or positive. (See scanning negatives
If you need to use a digital camera, your best bet
is to maximize the camera's quality
setting to a level
will provide acceptable resolution
for the image at the size of the printed piece. The best camera option for
quality is RAW. For example, Let's say you need to create a
17 X 22 inch
sign with an image
13 X 20 inch space. Let's also say we took the image with a
medium level SLR digital camera in the RAW setting. (Please note quality
and settings are different from camera to camera.) In this example
the captured RAW image is 240 ppi at 3008 X 2000 ppi.
This image is:
240 dpi @ 3008 X 2000 and is approx. 12.5 X 8.33 inches
If we take this image into Photoshop and resize the image using...
Photoshop > Image > Image Size
Turn off Resample image
Set the resolution (ppi) to 150, the image size will change to 20
X 13 ppi.
Though we changed the ppi, the pixel dimensions did not change. Please
keep in mind that though 150 ppi is acceptable, 300 ppi is preferred and
attainable only through scanning.
Scanning Negative, Positive,
The best option for quality is to scan your media with a high quality
scanner. When scanning, the higher the resolution and bit rate is
important; however, operator skill and knowledge is also very
important in capturing a quality scan. We have years of experience
and can scan a large variety of film media including 35 mm, and
medium and large format. Please see Pricing
- Prints and Services for scan prices.
