Color correction improvements
by Ray Reinertson
I will continue with my last column of
color reproduction improvements at The (Cleveland) Plain Dealer (see
N&T, April 2001).
The original question, submitted by
Kelly Cline, quality assurance manager at The Plain Dealer, was: How can we best
formulate a plan to improve the consistency of our color reproduction quality at
the Cleveland Plain Dealer?
This month, Cline presents his
insights into improving the color reproduction quality.
In June 2000, The Plain Dealer
began to investigate the use of color management technology as a means to
further improve its color reproduction quality, since existing standards for
handling and communicating color were no longer moving The Plain Dealer toward
its quality improvement goals.
The Plain Dealer hired Reintech
Inc. and Chromaticity Inc. Reintech would concentrate on our printing process,
while Chromaticity would focus on improving our proofing.
In the pressroom, we verified that
current printing process conditions were within original specifications or
better. Once this was done, a profile target was run on-press, analyzed, and a
file created that could be tested within our workflow. This allowed us to
accurately proof an image and improve the process of preparing an image for the
newspaper — optimized for The Plain Dealer’s specific printing conditions.
This did not mean that our color
image quality and consistency would necessarily improve; it only meant that
people could now predict how an image would reproduce in our newspaper. This
ability to predict early in the process would become the real power that color
management would bring to The Plain Dealer.
Now that we knew color management
would work, we had to make a decision — how far do we take color management?
There were, of course, systems and
workflow issues to consider. Working with Mike DiCosolo of Chromaticity, we
focused on how and where the use of color management would have the greatest
impact on improving quality, while utilizing existing technology at The Plain
Dealer.
The following is a list of some of
the most important steps taken to implement color management and the rationale
behind the decision:
• Purchased Gretag Macbeth
ProfileMaker software and spectrophotometer — allows The Plain Dealer to
become self-sufficient in the administration and continuous improvement
initiatives that involve color management.
• Added The Plain Dealer press
profile to the CMYK setup on Macs that work with editorial color — provides a
means to optimize an image, both view and output, for The Plain Dealer printing
process and conditions.
• Purchased and profiled a Cannon
BJ 8500 proofer to be used in our prepress imaging area — enables staff to
quickly assess if a photo requires further enhancement and toning before image
is placed on a page.
• Profiled all HP broadsheet
plotters — provides full-page proofs used to review a variety of items.
• Implemented the use of the
press profile and calibrations procedures on monitors deemed critical to color
quality — provides operators with a calibrated view of an image optimized for
our press conditions.
• Conducted profiling tests with
Nikon D1 digital camera — compensates and neutralizes for variations in
lighting.
• Created press profiles for
commercial printers that handle outsourced advertising materials — enables
images created by The Plain Dealer to be compensated correctly and optimized to
a commercial printer’s process and conditions.
• Shared press profile with an
advertising agency that creates our promotional materials — allows agency to
work with image optimized for The Plain Dealer’s printing process.
These steps constitute the bulk of
what The Plain Dealer had to do in order to color manage its workflow. While our
work is far from done, we have made great improvements in our reproduction
quality and consistency with the use of color management.
As I look back, there are two
things that stand out in my mind about this project — color management is as
much about communication and cooperation as it is about technology, for without
everyone working together, we could have never come so far so fast.
The project makes everyone involved
acutely aware of just how important calibrations are. Without calibration, there
is no predictability. With no predictability, proofs don’t match final output,
communication breaks down, poor decisions are likely to be made and quality will
fall off.
With color management in place,
proper documentation and people working together, we have a road map to get back
to where we are today … a far better place than we were six or seven months
ago.
