A perfect bundle for color matching of monitor and proof!
Just Normlicht, pioneering leader in the production of visual color control
devices for the graphic arts and photographic industries and Color Solutions,
worldwide recognized premier supplier of calibration and profiling solutions for
the graphic arts industry, introduce their latest innovation at the GraphExpo
2006 (Chicago, 15-18 October). |

The »JUST Color Communicator2« is equipped with a USB communication interface
that enables the »adJUST« and »basICColor display4« software to adjust
the brightness of the viewing cabinet and to match the image displayed on the
monitor with that in the viewing cabinet automatically and with the utmost
precision. For the first time, the image on the monitor and the printout can be
compared directly under standardized light.
The lack of a suitable interface did not make it possible to adjust the
brightness of a viewing cabinet by means of a software program before.
Therefore, visual control and changes were made manually using a slider.

Now this procedure is completely automatic and controlled with measuring
technical equipment. Firstly, the monitor is calibrated using »adJUST« and
»basICColor display4«: the target brightness of the viewing cabinet is
determined and later measured with the same color measuring device. Then the
software calculates the optimal adjustment and sets the Color Communicator2 via
a USB interface accordingly. Everything occurs automatically: the user simply
puts the measuring device on the monitor and then into the viewing cabinet. The
result is that a soft proof on the monitor and the proof in the viewing cabinet
look exactly the same. |

Open your eyes... in the digital workflow!
You can look at it whatever way you want: Colour management is not just a
digital affair. The human eye is still required because colour management would
be self-defeating without any visual colour comparison. In the digital workflow,
colour management must offer standardized testing methods and monitoring
devices, true to the priciple: "Standardisation is a prerequisite for the
creation of colour corrected print data."
ICC profiles, sheet-fed colour
control bars, test charts, paper grades, calibration and colour measurement are
as much part of the standardized process as is the use of the proper tuning
light. So, keep your eyes wide open! |

Illuminant mode D 50, i.e., standardized light featuring a colour
temperature of 5000 Kelvin, is compulsory when it comes to the visual colour
sampling of copies, digital proofs and printing runs. If ink-jet proof
systems are employed, the fact that ink-jet colours and printing inks exhibit
metamerism must be taken into account. Metameric colours, which appear to be
exactly the same if exposed to a particular illuminant, may all of a sudden show
distinct differences in color when light conditions change. For
ink-jet proofs, normalized colour comparison is possible only if the D 50
standard illuminant is used.
Issued in 2000, the international
ISO 3664 standard has redefined the viewing conditions for the graphic arts
industry. It makes standardized D 50 illuminant light mandatory for prepress and
press activities. ISO 3664:2000 is the basis on which all JUST NORMLICHT
appliances are manufactured. |
