Textile RGB - FOGRA58-beta towards an upcming resesarch project

Working Title: Improving textile colour communication

"TextileRGB" represents a planned Fogra research project. In light of this there are already some tool available for internal testing. This is right now a characterisation data set and a corresponding RGB-based output profile - to be used as an RGB working space.

Extended description:

Digital textile printing currently covers various different market segments, which differ mainly in the application, the selection of natural or synthetic textiles and the matching inkjet dye classes. These are clothing (fashion or "fast" fashion, athleisure, sportswear, swimwear), home textiles (interior decoration, carpet), soft signage (printing of advertising on textiles) and technical textiles (workwear, medical, partly also sports). Especially the latter are partly subject to special functional requirements.
The colour communication workflow in digital textile production is facing great challenges. This begins with the selection of a suitable RGB exchange colour space. The creation of the designs from typical Adobe programs results in databases, which are usually created in sRGB or AdobeRGB color space. The latter in particular is much too large compared to typical textile references (such as Pantone TCX fans) or common digital printing colour gamuts. This leads to time-consuming and cost-intensive, mostly iterative colour adjustments at the print service provider. Therefore, a suitable RGB working colour space is to be developed in this project. A second, equally big problem in colour matching is the discrepancy in colour measurement. Most colour definitions in textile printing are based on the standard illuminant D65 and the 10° standard observer. The ICC profiles of the typical digital textile printers are by definition based on D50 and the 2° standard observer - whereby a conversion of the respective CIELAB colour values is not clearly possible. Therefore, a continuous spectral workflow based on the new ICC standard V5 ("iccMAX") is to be developed, implemented and tested in this project. The third focus of this project is directed at the test print production of both "paper proofs" (digital test print on textile-like conventional proof papers) and "textile proofs" (digital test print on the later production machine). Specifically, specifications for the categorization of typical textile substrates with regard to surface and brightener content, for the selection of the proof paper and the necessary colour adjustments and matching conditions are to be developed. In summary, a standardization concept is to be designed that will lead to a new ISO standard (ISO 15311-4) on the one hand and to a separate chapter in the Process Standard Digital Printing (PSD) on the other.
