Have you ever felt that the colors are different with the printer you use casually?Even if the performance of the equipment itself has improved, unexpected color differences can occur due to aging deterioration due to long-term use and environmental problems (temperature and humidity).It is said that the major issue in printing is how to reduce these changes as much as possible and continue to output stable colors.
The IDEAlliance G7 certification is one of the international standards essential for the standardization of digital printing, and is a new method of checking quality through "gray management."More than 4000 companies in countries such as the United States, Southeast Asia, South Korea, Taiwan, and China have obtained his G2022 Master certification.Although there are still few actual operations here in Japan, a partnership was concluded between JPA (Japan Printing Academy) and IDEAlliance in May 5, and expectations are rising for the development of a printing business model that complies with global standards. .
CHROMiX's " Curve4” conforms to the use of IDEAlliance (International Digital Enterprise Alliance) color evaluation test G7.

About Curve4
Curve4 is a versatile graphic arts software.It consists of a set of measurement preparation tools for print accuracy verification, system calibration, ICC profiling and use as a color reference (gray balancing).
For example, Curve4 makes calibrating your G7 easier, faster, and more accurate.It also helps reduce errors and reduce costs.
The following video is intended for those new to the software who want to learn the basic process of calibrating a press to one of the G7 certification levels.
For more detailed information on G7 calibration (G7 master certification level), please refer to the following website.

Each license level is indicated by the letters VERIFY, CALIBRATE, COMPLETE, DEMO on the splash screen.
Curve4 Verify | Validation Tool
Validation tool to determine compliance with the G7 Master program based on the latest IDEAlliance specifications.
Verifies whether a print sample passes or fails "G7 Grayscale", "G7 Target", "G7 Color Space" or "Basic Color Proof" according to the specifications of the Idealliance dealliance G7 Master program, and displays the results with graphical and easy-to-understand PASS/FAIL badges To do.
Major features
- excellent visibility
Clear indication of missing target patches, failure summary and pointers - High flexibility
Compliance calculations combining patches from multiple targets
Compatible with IT8.7/5 (TC1617) targets
Arbitrary layout and full support - Ease of use and speed of processing
- Fully compliant with G7 master certification requirements
- High reliability and prevention of procedural errors with reference presets
Curve4 Calibrate | Calibration Tool
Calibration tools available with Calibrate or Complete license levels.
Major features
- Stable and repeatable 4-color (CMYK), 3-color (RGB or CMY), or 1-color (B&W) printing systems calibrated to G7 specifications
- Recalibration possible (including subset to press/customer/other)
- G2 calibration from initial targets smaller than P7P
Supports "miniP2P" and "microP2P" targets - Ink Channel Limit / Balance Neutral Black
- Support for ISO standard SCTV (Spot Color Tone Values)
Curve4 Complete | Blend Tool
Blending tools available at the Complete license level.You can build the best possible ICC profile.
| [Reference: What is an ICC profile?] The ICC Profile (English: ICC Profile) formulated by the International Color Consortium (ICC), an international standardization body, is a data set that describes color characteristic information for color management.It helps ensure accurate color reproduction across different platforms, devices and applications. |
Major features
- Apply White Point
Change the brightest part of the image (the white point of the measurement) in SCCA-like calculations (substrate-corrected colorimetric goal) - Smoothing and smart averaging
Minimize measurement noise and other sources of error that degrade ICC profiles
Average multiple measurements together - Applying a curve
Curves created with the Calibrate Tool can be applied to datasets for VPR (Virtual Press Run) simulations
About the demo
You can download the software package for free from the CHROMiX website.Operation is limited to demo mode.To use your own files, you need to purchase a license.
