Cielab. xyz: A unique resource for specialists in colorimetry and printing
If you work in the field of printing or lighting engineering, then the cielab website. xyz is probably familiar to you. This is not just an information portal, but a real tool for professionals. Everything related to accurate color measurement, standardization of processes and work with spectra is collected here. The main idea of the project is to combine science and practice to help printers achieve perfect color matching.
You can find many useful tools on the page. For example, there is a spectral calculator that allows you to work with CIE Lab or CIE LCh data. It calculates various types of delta E, including modern 1994 and 2000 standards, as well as CMC. This is very convenient for those who do color proofing and want to know exactly how much the color deviates from the standard. A color converter with sliders is also available, which makes the setup process more visual.
Profiles and standards for offset
Particular attention is paid to profiles for color separation. The site presents specialized solutions, such as Wide Gamut CMYK and adaptation of FOGRA39 for conventional printing houses. There are even profiles for drawings and business graphics where clear lines are important. Interestingly, the developers offer profiles based on ISO Coated FullGamut4, which enhance local contrasts. For digital lovers, there are NonPrinted CMYK as AdobeRGB and profiles in Display P3 coverage.
- Test cards and references:Data available according to ISO 12647-2:2004Amd standards. 1:2007(E). You can download references for different types of paper and observation geometry (045 or 450).
- Processing scripts:There is a convenient script that processes data arrays from BEGIN_DATA to END_DATA. It understands tables with numbers and automatically assigns Lab values to the last columns. It works quickly if the browser does not slow down.
Forum and community
In addition to tools, the site has a forum for colorists and printers, opened back in August 2004. There you can find answers to complex questions, for example, about the color discrimination capabilities of a trained observer. This is a living community where they share experiences and solve practical problems. Recent topics show that the site remains relevant and useful for those who want to understand the intricacies of color.
Overall, cielab. xyz is a powerful resource for those who value accuracy. There is no unnecessary water here, only specific data, profiles and calculators. If you want to improve your print quality or better understand the physics of color, this is the place to go.
Frequently Asked Questions
What is the spectral calculator on this site?
It is a tool that takes input data in CIE Lab or CIE LCh format and calculates the difference between colors using different formulas such as delta E 1976, 1994, 2000 and CMC. It helps accurately assess color deviations.
What reference standards are available for download?
The site contains references from Fogra39, Fogra45, Fogra46, as well as IT8. 74 for different versions. There are data for Black backing and White backing with different types of paper.
Can the script be used to process large tables?
Yes, the script processes data arrays if they are formatted correctly (BEGIN_DATA_FORMAT and END_DATA_FORMAT). It understands spaces instead of tabs, but large volumes may require processing time.
What are Wide Gamut CMYK profiles used for?
These profiles allow you to expand the color gamut of your prints, providing richer, more accurate colors than standard modes. They are useful for high quality proofing.
