Data Management

KMS Komori Management System

KMS basic functions include transferring job preset data to the press and providing an operating status monitor, err or log monitor, and maintenance information as well as an interface to other networks. Job data from the MIS-linked K-Station and preset data from the CTP workflow linked-PCC are received over the network for setting the functions of the press. Real working data from the press is received, managed and stored, and can also be sent as feedback to K-Station over the network. (Integrated with PQC, touch-panel operation)

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 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 (KMS), 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 KMS 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 Komori KHS System

KHS embeds preset data in the operation sequence of the press to ensure a quick startup and reduced paper loss. KHS is a revolutionary productivity enhancement system developed to reduce job changeover times and paper loss to the absolute minimum.

KHS performs one-step color register adjustment and color matching by using accurate CTP plates and preset data converted from CIP4/PPF data.

KHS reduces the consumption of resources by cutting paper loss on startup to tens of sheets and by shortening makeready time. An ink film that is close in thickness to that used for printing is created on the ink rollers by the programmed pre-inking and removing function, enabling very fast startup.

Shortening makeready and reducing paper loss draws out the full performance potential of the press and significantly improves productivity.

KHS-AI KHS-AI(Advanced Inteface)

This version adds folder adjustment to conventional KHS production support, making it an integrated management system by means of the multifunctional self-learning function. KHS-AI evolves by continuously learning compensation and optimization through analyzing automatic color matching for print-quality fine adjustment and for changes in color.

PDM PQC Data Manager

This system makes presses that are not compatible with KMS 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-SII Print Density Control-Spectrophotometer

The PDC-SII Print Density Control-Spectrophotometer scans and measures the color bar on printed sheets, converting the results to numeric data for display and providing feedback to the press-side as necessary. Compared to the conventional PDC-S, several functions have been enhanced and ease of use during printing is significantly improved through faster measurement and display.

Color adjustments that once depended on the operator’s visual check are controlled by numeric data obtained by measuring and analyzing color evaluation indices such as solid densities, dot gain, trapping, contrast, L*a*b, ?E, hue error, and grayness. This approach vastly increases color consistency and operating efficiency.

PDC-SII incorporates a feedback control function that automatically calculates the appropriate ink key openings when color variation occurs, feeding this data to the press so that densities approach target values. The handheld scanning instrument enables spot assessments anywhere in the image, data registration of special inks, and color management based on spectral reflectance.

High-level color management, reduced operator workload, and higher operating efficiency. PDC-SII: The essential system for printing standardization.

K-ColorProfiler K-ColorProfiler

For the difference between the proof and final printing, greater utilization of proofers such as high-end DDCPs or inkjets as a result of CTP systems coming into mainstream use has raised the issue of the proofer having a different color gamut (reproducibility domain) from the printing press. K-ColorProfiler solves this by enabling the quick creation of a high-resolution ICC profile by measuring a unique K-Color chart with PDC-S. A proof that is very close to the printed item – can be created by sending the ICC profile to the proofer as feedback.

K-ColorMatchPro K-ColorMatchPro

K-ColorMatchPro performs high-precision color matching with the digital proofer based on the ICC color profile. The ADO (Autonomic DLP Optimizer) automatic color compensation processing function minimizes delta-E (color difference) between the printing press and the digital proofer without any manual fine adjustment.

K-ColorMatchPro accepts all compatible ICC profiles because it does not depend on any particular profile generation package. In addition to direct output on the Epson StylusPro(R) printer, K-ColorMatchPro outputs TIFF files with color-matched DLP (Device Link Profile), thus enabling output on multiple different digital proofers.

PDC-LITE Scanning Density Control System

PDC-Lite is a scanning density control system that can be equipped on Komori sheetfed printing presses up to 32 inches in size for density control of 4-color process inks.

Since PDC-Lite 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).
