[NTG-context] RAL colours
Of and on, I have struggled to find a colour space that is expressive enough for printing, but convenient to access through ConTeXt for day-to-day usage. I find with X11 that the emphasis on screen skews the colours to be brighter than what is desired, especially if one is dealing with coloured stock---say beige kraft---as I am doing with my current bit of typesetting. In this process I have come across the RAL colour space: http://www.ral-farben.de/content/application-help/all-ral-colours-names/overview-ral-classic-colours.html whose values can be conveniently (sort of) accessed at: http://rgb.to/ral/page/1 For my immediate needs, I have simply created a set of: \definecolor[colourName][h=HH] However, I am wondering if it might make sense to have a colo-imp-ral.mkiv? So my questions would be: 1. Is the RAL colour space a decent one for printing purposes? What would be disadvantages, if not? 2. Does colo-imp-ral.mkiv exist already? 3. If not, would others find it useful to have a colo-imp-ral.mkiv? If it doesn't then I would be happy to prepare one and submit it. Many thanks. -- Pavneet Arora m: 647.406.6843 Waroc Informatikt: 416.937.9276 ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___

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.

Re: [NTG-context] Different renderings of cross references
Trying once more…
Hi all,
As explained in the example below, I would like to setup the referencing
mechanism so that a cross reference within a given chapter gives only the
number of the section and that of an equation, while if the same reference is
used in another chapter then the number of the chapter is also included. Is
this possible with mkiv?
Best regards: OK
Here is a minimal example of what I would like to obtain:
% begin prefix-reference.tex
\setupinteraction[state=start]
\setupformulas[prefix=yes,prefixsegments=chapter:section,way=bysection,location=left]
\def\eqref#1{(\in[eq:#1])}
\starttext
\startchapter[title=Introduction to sequences of numbers]
\startsection[title=On sequences,reference=sec:Sequences]
\placeformula[eq:Number-e]
\startformula
a_{n} := \sum_{k=0}^n {1 \over n!}
\stopformula
\stopsection
The sequence defined in equation \eqref{Number-e} cannot converge to a rational
number.
(Here I would like to have (1.1) instead of (1.1.1)).
\startsection[title=Cauchy sequences]
The sequence defined in \eqref{Number-e} satisfies $a_{n} a_{n+1} 3$ but it
does not converge to a rational number.
(Here I would like to have (1.1) instead of (1.1.1)).
\stopsection
\stopchapter
\startchapter[title=What is a real number]
\startsection[title=Limits of Cauchy sequences]
We proved in \in{section}[sec:Sequences] that the sequence defined in equation
\eqref{Number-e} cannot converge to a rational number.
(Here I would like to have section 1.1, and equation (1.1.1)).
\stopsection
\stopchapter
\stoptext
% begin prefix-reference.tex
