2. Resolution . Resolution is measured in dots per inch or
dpi . 300 dpi is sufficient to get the best possible quality
from most images. A 72 DPI image will look fine on screen
but WILL NOT print well. Graphics and logos found on
websites are typically 72 DPI. The image below was print-
ed from a 72 DPI image. Notice the jagged edges.
Remember, print quality settings found in the label printer
driver will have no effect on improving a low dpi source
image.
On the other hand, resolutions higher than 300 DPI will
not produce better quality but may require more RAM to
print and hard drive space to store. They could even slow
down the print process.
3. Image File Format. Most graphics are created in a graphic
application. Since this graphic application is not usually on
the same computer as the label printer doing the printing,
it is necessary to export the graphic into a universal format
that can be read by other programs. We recommend TIF
and BMP files for graphics. These formats are uncom-
pressed. JPG files also work well for graphics that include
photographs. All three formats can be imported into the
NiceLabel application.
