Newsday puts
some science into color evaluation
by Lisa Larson
Managing Editor
During the past year and a half,
Newsday has expanded its overall color management and proofing solution to
include GretagMacbeths ProfileMaker Pro color management software and a
SpectroScan spectrophotometer, as well as another BestColor CMS for its magazine
workflow.
Newsday (Monday Friday,
576,692; Saturday, 417,949; Sunday, 663,220) already had in place five Xerox
DocuColor 12 copier/printers driven by Splash G620 color servers, now made by
Electronics for Imaging Inc. These devices are used for all newsprint proofing.

A Newsday features section is very close
on
color reproduction from proof (bottom, right)
to press (top, left).
We print more color than most
other newspapers, said Ron Chiavaro, director of prepress and quality
assurance at Newsday. We needed a proofing system that would quickly and
accurately predict what we would see on press, so we could be confident that we
were making the correct color decisions early in the process.
The Long Island, N.Y.-based
newspaper, owned by Tribune Co., typically produces an edition that contains
between 50 and 60 color pages a day. Before the latest proofing system was
installed, Newsday was still judging color proofs by eye, evaluating multiple
proofs and adjusting curves on the Splash server to match the press sheets.
We did that hundreds of times,
and were very happy with the results, but we could see that there was more to
accomplish in the way of quality, Chiavaro said.
In 1994, Chiavaro instituted
graybars to take the subjective measurement of color out of the pressroom and to
ensure consistent printing across all 10 presses.

Newsday uses the GretagMacbeth SpectroScan
to measure proof and press targets.
Then Newsday installed the first
Splash/Xerox proofing solution, which was a great improvement, but Newsday
wanted to further introduce a scientific element to the process. During this
stage of the systems evolution, James Kober, imaging manager at Newsday,
instituted the use of International Color Consortium profiles and implemented
the use of Delta E measurements, which measure the difference of the colors
coming off the proofs and the colors coming off the presses.
Our utilization of color
management tools and ICC profiles have enhanced what was a great system into
what we consider the best system available, Chiavaro said.
Shortly following the installation
of the upgraded Splash/Xerox proofing solution, Newsday purchased the
ProfileMaker Pro color management software from GretagMacbeth, along with a
SpectroScan spectrophotometer.
We control color by measuring
it, Kober said of the SpectroScan and ProfileMaker Pro software.
Newsday uses the ProfileMaker Pro
software to perform the comparisons of the measurements that come off the
presses and the measurements that come off the proofers.
The implementation of the
Gretag-Macbeth CMS and the Splash/Xerox solution brought Newsdays Delta E
down to 6 from a Delta E of 9.
After custom profiles were created
for each DC12 copier, and some work was done with Richard Falk, the chief color
scientist at what was then Splash Technology Inc., the Delta E dropped to 3.5.
When we measure Delta E, we are
measuring a sample that has been printed at the exact solid densities that we
run here and comparing that to a measurement of a calibrated proof, said
Kober. A Delta E of 3.5 is extraordinary. A Delta E of 6 for commercial
printing applications is considered very good.
BestColor in commercial
On the commercial side, Newsday is
using a color management system from BestColor and printing proofs on Canon
printers. Newsday produces several monthly magazines, as well as books and
special sections of the paper, and has always used a film-generated DuPont
Waterproof, which cost about $35 per page.
We went through a labor
reduction in that area and we needed to find a digital proofing solution that
would allow us to produce a lot of proofs in a short period of time without the
labor, said Chiavaro. We bought a system that cost us a total of $25,000
and the proof costs us about $2.50 apiece. This year alone, we are going to save
upwards of $150,000 in materials.
