Asss • The asssments can be viewed in many
d ifferent ways on th

r eport. Color space comparisons between two ts of measuring data can be reprented in two or three d imensions.
Long-term analysis • Several ts of measuring data can be read in and compared. They make it possible to analyze color behavior over a longer period of time. It is therefore possible to document a quality standard and color fidelity is no longer a subjective nsation. Proof report • Quality Monitor supplies a report on the color accuracy of the proof. This report can be handed over to the customer in the form of a certifi-cate together with the proof.人际沟通与交流
Measuring devices and tests
The programs of the Prinect Color Toolbox work with many of the leading spectral photometric and densito-metric measuring devices and support standard tests in accordance with ISO 12642, including ECI 2002, IT8.7/3 and IT8.7/4.
Quality Monitor is the ideal tool for amless process and quality monitoring.

Any fluctuations related to the equipment can be recognized and smoothed out with a connectable profile smoothing. This makes Profile Tool the ideal tool for the creation of generic profiles to describe a printing standard.

ICC output profiles for the proof • The creation of profiles for the proof is optimized in order to achieve the best possible color adjustment. The iterative proof correction makes it possible to achieve a level of accu-racy in the profile, which reduces the average color

f from the print to an absolute min-imum. An integrated color calculator converts spot colors to the CMYK values of the proofer. This means that the expanded color space of the proofer is fully utilized. The PANTONE® and HKS color tables are in-cluded in the software package.
Color measurement and correction • The Profile Tool measures true spectral values in the color fields. All the desired values such as Lab, XYZ, CMYK or den-sity can easily be calculated from this. The program can therefore u values, which have been m easured once, in many ways. Optical brighteners in papers, which are interpreted by measuring devices as shades of blue and would therefore lead to errors in the pro-file calculation, are corrected by the Profile Tool on a

Calibration and profiling with one proof run •default什么意思
N ormally a test sheet can be printed first to compile an ICC profile, if a process calibration has been carried out previously. The Profile Tool can also calculate good pro-files from the measuring data of an uncalibrated print taking account of the calibration data of C alibration Tool. This means it is no longer necessary to print and measure test sheets repeatedly, which is time-consum-ing. This saves not only time and materials. It also helps to cope with color management in the overall printing process rapidly and with certainty.
Device Link Profile • In many cas it is necessary to align the print customer’s documents directly with one’s own production environment. Profile Tool has the functions necessary to do this. This also includes UCR/GCR functions in order to u less colored ink to achieve the same impression of color. This means that the gray balance can be stabilized and color fluctua-tions avoided. In addition, it is possible to limit the maximum inking of every object, whereby the color ad-justment on the printer can be managed more easily and quickly. Fine-tuning is generally carried out with device link profiles. The Profile Tool creates extremely sophisticated device link profiles for u in the Prinect wo
rkflow. There is no need to buy an expensive addi-tional solution for this purpo, as all the necessary functions are already integrated into the profile. P rocess conversions can therefore be carried out from one CMYK printing process to another with a high level of quality.

Separation of up to ven colors • By using the
o ptional multi color extension, it is possible to produce color parations for 5-, 6- and 7-color printing. The inks for this can be lected in a quence, which makes n in colorimetric terms. This means that frequently ud color models such as Hexachrome® or HiFi Color are supported to the same extent as
c ustomer-specific models.

Calibration Tool
Central management of all the calibration data • Calibration Tool makes it possible to create and cen-trally manage all the calibration data for the lineari-zation and process calibration of CtP platetters and direct-imaging press. The tool supports both the
l inearization of platetters and the calibration of the entire process ction right up to printing.
shittahThanks to Calibration Tool it is possible to t up as many spot colors in one data t for process calibra-tion as desired. This means that a data t can con-tain either all the process colors or be ap p lied indi-vidually for each paration.
A central data pool • In a company with veral plate-tters the curves for each output device can easily be arranged and managed. If veral platetters of the same type and using the same materials are de-ployed at the same time, Calibration Tool can be ud to organize a central data pool. It is possible to feed the RIP imagetter stations with the right curves for each job from there – creating ideal conditions for consistent quality at each station.
Simple application of calibration curves • The print parameters such as type of paper, ink ud, solid tint densities and printing press are stored with each cali-bration curve. Calling up the right curve is controlled by indicating the parameters. Calibration Tool offers only tho curves, which are actuall
y suited to the print parameters in the job. This not only makes o peration easier, but also helps to avoid errors.
The actual dot gains are generally described by process standards. A range of standards is already provided with their dot gain curves. It is possible to define one’s own process parameters individually for corporate standards.
The resulting process curves can be smoothed out in order to compensate for measuring errors.
In addition, Calibration Tool offers numerous editing functions to compile new curves, which are superim-pod on an existing calibration. If one parameter changes, then a test sheet does not have to be printed and measured from scratch. All that needs to be done is to calculate the changes using the existing curve.
A new, adjusted curve is then available for the next t of plates. Rapid calibration with Prinect Image Control • The interaction of Calibration Tool and Prinect I mage Control color measurement system provides superb rapid and preci calibration with Mini Spots. The mea s uring elements are assd in one go and a fter a few conds the measuring data are available for a calibration adjustment.
RIP-independent installation • Calibration Tool does not have to be installed on the RIP station. It is also possible to t up a parate calibration station in which the curves are measured and compiled central-ly for the connected RIP imagetter stations. By ad-ditionally installing Profile Tool, this station can be
u pgraded to a central color management workstation within the company.
Quality Monitor
Seamless process and quality control • Print shops are increasingly applying for certification to a quality standard. This is associated with the requirement of being able to provide evidence of continuous compli-ance with the standard. This is where you need Quality Monitor: It is the ideal tool for amless p rocess and quality control. It provides every print shop with de-tailed analysis results.
Both printing companies, which already document the high standard through their certification, as well as companies, which are just starting out with standard-ized printing, can demonstrate the high quality of their work and prent it clearly at any time with Quality Monitor. Detailed reports, even compiled over a longer period of time, therefore rve both as documents for control as well as evidence of reliable production at a consistently high level.
All the decisive tasks of process supervision and
m onitoring the proof and print can be carried out with Quality Monitor:
Measure • Numerous keys, linearization strips and entire test sheets can be measured out with spectral photometers, densitometers or plate measuring
d evices.spectre
Compare • Quality Monitor permits comprehensive comparisons between two ts of measuring data, e. g. the deviation between the proof and print or print standard or the deviation in a print run.
