Resolution Considerations for Graphics, Images,
and Photographs
Graphics, images and photographs can come from many different
sources such as digital cameras, scanners, and photograph
CD-ROMs. Typical file extensions for images and photographs are
.bmp, .fpx, .gif, .jpg, .png, and .tif. For these images, resolution
decisions should be made based on the content of the image. When
possible, import images at the size you plan to use (actual size).
z Graphics and line art should be imported at the maximum
resolution. For best reproduction of raster graphics and line art,
the printer driver halftone settings should be configured to
enhance the critical feature. If the fill smoothness is critical, select
Smooth. If the edge detail is critical, select Detail.
z Images should be at least 200 dpi, and preferably 300 dpi. The
printer driver settings should be set to ColorSmart II. Or, if you
are using the Manual setting, select Smooth Halftone and
Screen Match color mode.
Note Image resolutions of higher than 300 dpi will produce significantly
larger files, but the print quality of the image will not necessarily
improve.
Using Digital Cameras
When printing images captured by a digital camera, you might have to
adjust the image quality. Adjust the images with the imaging software
that came with the digital camera. Generally, for the most accurate
color rendering, leave the digital image color mode in RGB. When you
print the image, the printer will convert the RGB information to CMYK.
For more information on adjusting the image quality of digital
photographs, see the imaging software documentation.
For photographs, use ColorSmart II setting in the Color tab. Or, if you
are using the Manual setting, select Smooth Halftone and Screen
Match color mode. For more information on printer driver settings,
see the online help.
