Re: [NTG-context] RAL colours

Many thanks Hraban! This is great insight into the printing world. Of course, Pantone has a dominant position on this continent at least, but as you stated, its proprietary nature keeps the palette from being distributed easily. So the question remains: if the X11 colourspace is found inadequate, is there another one that we might look for inspiration to create decent spot colours for document processing? Even if RAL colours are used for varnish, does that mitigate the use of their RGB values for other paints? Note, that I am not seeking exact calibration of colours, say for branding across different media; just a more expressive palette for print applications. Unfortunately, I don't have access to the Adobe products that you mention, and in any case would just want a convenient set of colours inside ConTeXt to create documents on the fly. For this type of work, are there any other "open source" palettes that we might look towards? Warm regards. On 04Apr15, Henning Hraban Ramm wrote:

1. Is the RAL colour space a decent one for printing purposes? What would be disadvantages, if not?

No, it’s not. RAL colors are defined only for surface colors, like lacquer (varnish? paint).

Printing colors work differently, they’re mostly transparent. A parallel to RAL in printing colors would be Pantone (or HKS in Germany, Toyo in Japan). But these are copyrighted, so we would be most probably not allowed to ship a library of these. (If I need some spot color, I look up the CMYK/RGB mix in Photoshop or InDesign.)

2. Does colo-imp-ral.mkiv exist already?

That would make no sense IMO.
