MORE DESIGN TIPS...
Digital Camera
When using a digital camera, the image capture should be set at
the highest resolution, even if it means sacrificing the number of
pictures that can be stored on a single memory card. The camera should
have a minimum of 2.2 megapixels of data capture; a higher number
would be even better, especially if the image will need to be enlarged
before reproducing it.
Scanning
When scanning photographs, a higher dpi equates to higher
resolution. But at too high a resolution, file size becomes an issue,
so maintaining 300 dpi at 100% is usually adequate.
Web Site Images
You should avoid downloading images from a web site. Typically,
they have been scanned at only 72 dpi and are saved as a JPEG file in
which pixels are discarded to save space, therefore making the image
inadequate for quality commercial printing reproduction.
Color Matching
Even when every attempt is made to match color in the final
printed piece to your original image, there are several variables that
sometimes make an exact match impossible. RGB (Red, Green, Blue) color
is captured by digital cameras and scanners. It is an additive color
system and represents the way a computer monitor displays color.
However, since RGB color is device dependent, the same image can look
quite different on different monitors, much the way you may notice a
variance in color on different televisions. All RGB files must be
converted to CMYK (Cyan, Magenta, Yellow, Black) before printing on a
commercial offset printing press. CMYK is a subtractive color system
that defines ink pigments and is not capable of producing the full
color range of RGB color. The type of lighting and reflectivity of the
stock can also affect the appearance of CMYK color.
