OTE: The Fiery allows you to use RGB or CMYK data when printing proofs for
an offset press run. However, sending data to an imagesetter usually requires
CMYK data.
Maintaining color accuracy
For the colors you see on your monitor to match those on your printed output, they
must go through color management, including precise calibration of your monitor and
Fiery. If viewing colors on the monitor is critical, consider using a professional
profiling software package and instrument, such as the EFI Color Profiler, to create a
monitor profile. A monitor profile enables application to compensate for the color
behavior of the monitor when displaying images. As a result, colors previewed on the
monitor more closely match colors in your printed output.
If you are not equipped or inclined to maintain accurate monitor color management,
you can opt for an easier approach. Determine which is more important to you—
printed colors or on-screen colors.
• If displayed colors are more important, trust your eyes and your monitor. Visually
select colors on your monitor, but be aware that colors will be optimized only for
your monitor. When the document is opened on other monitors, the colors may
look different. And even though printed colors may not match those on your
monitor, they will still print to the Fiery with good results.
• If printed colors are your priority, choose colors from printed samples. By using
sample colors, you ensure your printed output remains consistent, regardless of how
the colors appear on different monitors. Print the palette of available colors from
business applications and select colors from the printed samples. Color reference
files are included on the User Software CD. (For more information, see“Using color
matching tools with office applications” on page 3-24 and “Using color matching
tools with PostScript applications” on page 4-28.) You can also print color charts
from the Fiery and select colors by name or number from the printed samples.
Advanced applications allow you to define colors in the easier-to-control spot and
CMYK color spaces. For more advice on color selection, see “Choosing colors” on
page 2-19.
