Objective: At completion of this module you will be able
a printer utilizing given hardware and software tools.
We have already
covered monitors and scanners and although they are extremely important
to our workflow, the final destination for most image files will
most likely be ink on paper (print). Even though our monitor is
along with our scanner if the printing process is not controlled
or understood you are most likely going to be very disappointed
with the results.
As we discussed
in Part I of this tutorial a profile describes the characteristics
of our device. Ideally we would like this profile to be as accurate
and precise as possible, because we want to match what we see on
our monitor to our output device, at least as close as we can get
it. In fact if your color devices have been properly calibrated
and profiled to this point your final output should come very close
to matching your original digital camera file or scanned negative/print.
Many printer and paper manufacturers have created and freely distribute
"canned" or generic profiles
for specific printer, ink and paper combinations. These profiles
are often used with fairly good results, some users however discover
that they are not good enough. There is a plethora of software
applications and hardware devices that can be used to create
custom profiles. A custom profile is created with
your specific printer, ink and paper combination for ultimate precision
and accuracy. This module will walk you through the process of creating
a custom printer profile.

note that this device needs more power than can be delivered

connect the Eye-One directly to your computer.

case we have selected the Epson 2200 (Ink Jet Printer) and
an RGB target with 918 color patches. Even though the Epson
printer uses CMYK inks it is best to treat it as an RGB device
for profiling. The larger target (918 patches) allows for
a more accurate profile.

Select the Media Type that you are printing
too, IE: Velvet Fine Art Paper. Click on the Advanced
Settings button and select 1440 pr 2880 dpi for best
quality. Leave MicroWeave and Finest

This will turn off the print drivers internal color management

our ICC Color Managed
workflow, the drivers attempt to manage color is not part
of this workflow and if on tends to create problems.

Summary from the pull down menu on the left.
Look over the Print Settings and make sure
that they are set correctly before making your print. This
is just a good way to double check your settings before printing
your target file.
the Eye-One Spectrophotometer.
the Eye-One spectrophotometer before reading color patches
ensures accurate data. Calibration
brings the device back to a known state. The Eye-One includes
a white calibration target on it's stand/holder. It is specific
to the SN# of the spectrophotometer.
now measure all of the patches on the test target that you
printed. You have the option to read the patches one at a
time (very slow) or in strip mode. In this example we are
reading in strip mode. With the help of a plastic guide each
row is measured individually. The Eye-One is activated by
pressing the right hand button on the unit and slowly moving
over each row. Any errors will be noted and rows or patches
can be read again.
an image that clearly shows how the rows of patches are read.
Remember move slowly from start to finish, the software will
note any errors it encounters.
all of the patches have been successfully read, a measured
data (text) file can be saved. This text file can be opened
later and used to build a custom ICC printer profile or you
can skip this step and proceed directly to building your profile.
will use the measured reading from your test target to create
a custom ICC printer profile. This profile represents the
color printing characteristics of your printer, ink and paper
set-up. A custom profile should be created for each printer,
ink and paper combination you plan to use.
is a processor intensive task and may take a few minutes.
is the last step in the printer profiling process. Save your
new profile with a name that makes sense. It is helpful to
include the printer name, ink and paper type in your description
along with the current date. This file will be placed in the
ColorSync folder within your operating system and is now ready
completed all but one module. You're well on your way to understanding
how to use and implement an ICC color workflow. Before you proceed
however please go through the following review questions to test
on the correct answer
1) The printer
target should always be printed with the default settings in your
2) Even though
an Epson Ink Jet printer uses CMYK inks for printing it is best
to profile it as an RGB device with most profiling software packages.
3) You should
always profile your device (spectrophotometer) before any readings
are made from the printed target file.
4) ICC is an
abbreviation for the International Calibration Consortium.
5) Once you
create a custom profile with a particular printer, ink and paper
combination, in general you should not have to create another profile
for this set-up.
