Printer Quality
PPI (pixels per inch) and DPI (dots per inch) are terms used to
relate quality, size and/or resolution of prints and scanned
images. PPI and DPI essentially mean the same thing, the
size and perceived quality of the image. Printers are
normally sold with a certain DPI of print quality.

Print DPI
|
Perceived Quality |
|
300 |
Best.
About as high a DPI count as most printers can print and
about as sharp as the eye can see at a normal viewing
distance. Use for all prints over 8 1/2 x 11 |
|
200 |
Better.
For smaller prints, 8 1/2x11 or less.
|
|
150 |
Good.
Adequate, but not optimum, for small prints. |
|
100 |
Not
Recommended. |
Scanned Image Quality
Scanners are most often rated in PPI and range from 1200 PPI for
most flat bed scanners up to over 5400 PPI for drum scanners.
We scan at between 1200 and 3200 PPI which will provide you with
a file that can be printed at up to 11 x 17 when scanned at 3200
DPI. At 3200 DPI we can convert your 35mm film frames into
breathtaking, 14-million pixel digital images.
100% frame coverage A
conventional film holder, such as those included with flatbeds,
will often obstruct the borders of the 35mm frame. But why
settle for less than the entire image? Our scanners come
equipped with a specially designed 35mm Film Holder that allows
us to scan the frame from edge to edge.
The size of the JPG file will vary depending on the content
of the image and how well a particular image compresses.
How many images on a DVD? The
actual number of files will vary so the following chart is to
only be used as a guide. We will also place your images
into an "album" format so the "album" software will also require
some space.
We do not recommend saving images in any format of less than
2000 DPI. We also recommend that all files be saved in the
TIFF format for the greatest image quality. If you desire
JPG images, please order them in addition to the TIFF images.
