Yesterday, the professional team from CGS China was invited to our company for an in-depth exchange focusing on color and technology.
During the testing session, both parties utilized CGS professional software to conduct a high-precision comparative evaluation of our aqueous pigment ink against Epson OEM ink, validating the outstanding performance of our compatible ink with real data. Following the test, CGS experts provided a systematic software operation training for our engineering team, empowering them to further enhance their color management capabilities.
This exchange not only verified our product's strength but also laid a solid foundation for continuous product optimization and the pursuit of ultimate color accuracy. Moving forward, we will continue to be driven by technology, providing you with superior ink solutions!

Color management elements
1. CGS color management software
2. Measuring instruments
3. Digital printer
4. Printing materials
Testing process -4 color matching
1. EPSON P9380 printer original ink matching Gracol2006 standard
Printing Material: FANTAC UH180A Digital Sample Paper
1. 1 Detect the OBA content (fluorescent whitening agent) of printing paper and determine the measurement mode
Calculation method: Subtract M0 b value from M2 b value. If the difference is greater than 4, it indicates that the paper contains a small amount of OBA. M2 is selected as the measurement mode for the testing process. If the difference is less than 4, M1 or M0 is selected as the measurement mode
1.2 Four color matching process
1. linearization
2. Ink volume control
3. Obtain the maximum color gamut of the printer Establish a mapping relationship with the target ICC
4. Software second iteration
5. Spot color correction
6. Match completed
2. EPSON P9380 printer Jun code ink matching Gracol2006 standard
Printing Material: FANTAC UH180A Digital Sample Paper
