| Résumé : |
In many industries, defined colors are not only an important feature of the product, but also a growing challenge. Increasing demands on the appearance quality must be implemented more and more frequently and efficiently across global production networks. There, physical standards may enhance quality, but the digital processing and communication of color data is more efficient. |
| Note de contenu : |
- Digital communication of standards
- The path to digital color communication
- Profiling the spectrophotometers
- Improved agreement between instruments from different manufacturers
- Fig. 1. On the left, the typical behavior of measuring instruments made by different manufacturers as well as by the same one is displayed. In each case, the absolute values from different spec-trophotometers form a characteristic cluster. On the right, the data subsequent to profiling is shown.
- Fig. 2. A common color tolerance for products for car interiors (outside, dE00 = 0.50) as well as the IMA (Inside) required for digital communication of standards. If mean and maximum deviations towards the reference instrument are kept, the system error corresponds to the system error when physical standards are used - minus the disavantages.
- Fig. 3. The absolute agreement dE00 between color differences of RAL samples (PP) prior and subsequent to profiling. The required value of dE00 = 0.10 was achieved by the Ci7860 subsequent to profiling.
- Fig. 4. User interface of CAPQ software. All relevant information is included.
- Table 1. The results show an improvement of the IMA, meeting the required values. In particular, the maximum deviations were clearly reduced. Thus, the data situation allows digital communication. However, the samples must be described as ideal, i.e., opaque without differences in structure or gloss. |
