To achieve further optimization, Komori has specified seven "issue areas" and developed products offering solutions for these issues – Color Management, Operator Support, Short Makeready, High Speed Printing Stability, Material Loss Reduction, Production Process Optimization, and Environment Standardization.
Data Management
PQC Print Quality Controller
PQC is a remote control system for making quality-related adjustments to the press. In addition to remote control of ink, water and register adjustment, a variety of adjustments of press functions can be made using the touch-panel.
Main functions remote controlled by PQC (vary according to model and specification); Ink key opening, ink feed, ink oscillation timing adjustment, ink feed on/off and rate adjustment, circumferential / horizontal / skewing register adjustment, water feed, KHS-AI (Advanced Interface)parameter setting, auto dampening operation, printing unit selection, sheet thickness and sheet size presetting / fine adjustment, cleaning unit selection, automatic wash-up setting, and APC setting.
K-STATION K-Station
K-Station provides central control of multiple Komori presses and functions as an interface to outside systems (such as the Management Information System [MIS]).
This facilitates sending/receiving production data by JDF and permits data management.
K-Station sends the production control data and job control data in the CIP4/JDF data from the MIS and the CIP4/PPF data from prepress to multiple presses (KHS-AI), and supports press-side makeready tasks.
In addition, production and maintenance data can be managed and stored, and necessary information can be sent as feedback to MIS. Linkage with existing process systems is possible through CSV files.
PCC PQC CIP Communicator
PCC converts digital data from prepress into a PQC-format ink profile for the press.
Using the preview image from CIP4/PPF data to calculate the area ratio and presetting the ink keys with this accurate data has become standard practice in the industry. PCC converts PPF data and CMYK-TIFF data into PQC ink key data for Komori presses. When the setup includes KHS-AI (Advanced Interface)and the network, prepress data can be automatically converted and sent to the press by an automatic conversion function (hot folder function).
Komori presses equipped with earlier models of PQC transfer data by magnetic card, and presses with newer models use floppy disk or the network.
KHS-AI KHS-AI(Advanced Interface)
KHS is an innovative productivity enhancement system developed to
reduce job changeover time and paper waste to an absolute
minimum. The system uses job data from the MIS-linked K-Station
and preset data from PCC, which is linked to the CTP workflow.
Plates output by a CTP system and preset data calculated from
CIP4/PPF data enable first-pull register accuracy and color matching.
The pre-inking condition is automatically adjusted for the image to
be printed. Higher speed at the start of printing and minimizing
waste paper at startup enable shorter makereadies and a significant
reduction in the use of printing resources.
KHS-AI (Advanced Interface)with self-learning is a further evolution of this KHS system.
Color matching is optimized by constant analysis and automatic
compensation of the image area ratio and ink key openings. Such
analysis and compensation is made with respect to the machine
condition, the printing environment and changes in the printing
materials. On sheetfed presses, KHS-AI (Advanced Interface)air and register adjustment
preset functions ― corresponding to the paper size, thickness,
grade and grain ― ensure stable sheet feeding and delivery. On
web offset presses, all tasks, including changes in the fold
specification, are automatically controlled, substantially reducing
makeready time and paper waste. In addition, KHS-AI (Advanced Interface)manages the
operating record, status history and maintenance data of the press.
The system includes a self-diagnostic function for troubleshooting.
Customer support also benefits from the ability to accommodate remote diagnostics in an emergency.

PDM PQC Data Manager
This system makes presses that are not compatible with KHS-AI (Advanced Interface)compatible with the DoNet network. PDM is a network compatibility system that facilitates presetting PQC by receiving job preset data from PCC or K-Station over the network and sends results data such as sheets printed and paper loss to K-Station.
Color Management
PDC-S II Print Density Control-Spectrophotometer
PDC-SII is a support system for evaluating print quality before
the operator starts final printing and for implementing print
room standardization.
PDC-SII scans the color bar on the printed sheet and measures
densities, dot gain, hues, and color deltas, which are then
clearly shown on the monitor. The feedback function for
density changes during a run calculates the amount of
adjustment needed from the measured value and sends this
information to the PQC.
PDC-SII provides spectrophotometric data, making it very
suitable for measuring special colors. In addition, the handheld
scanning instrument allows spot assessment of densities and
hues anywhere in the image. Measurement results can also be
printed out for use in reports.
PDC-LITE II Scanning Density Control System
PDC-Lite II is a scanning density control system that can be equipped on Komori sheetfed printing presses up to 40 inches in size for density control of 4-color process inks.
Since PDC-Lite II enables numeric density control with easy operation at a low investment point, it is the ideal entry system for printers who intend to implement full-fledged numeric control of print quality. Measures densities, dot gain, trapping, contrast, hue error, and grayness, with results displayed on a touch-panel monitor using a range of graphs.
Operation is simple and intuitive even for operators with short experience thanks to an interactive interface. Equipped with a function to move densities toward target values by feedback of density measurements to the press (PQC).
