Historical PDF layout: 1979 to 1986 layout

[ronaldtse]

During this period ISO used a "prettier" layout that has a wide header.

These are PDF samples from iTeh that provide a good demonstration of the layout.

ISO-7716-1985.pdf
ISO-5580-1985.pdf
ISO-1765-1986.pdf

Additional samples:

ISO-4219-1979.pdf
ISO-18-1981.pdf

Here's a full document found on the Internet so we can see how the pages end.

• ISO 3738/1-1982(E)

ISO XSLT updated for the layout.
To enable layout add the document attribute:
:document-scheme: 1972.

Oh wow I realized that the fonts used in this layout were different in different years.

The layout change occurred in 1972 to 1978 vs 1979 to 1986. So maybe we should add one "1979" layout.

1972 to 1978 cover heading

1979 to 1986 cover heading

Cover title

1972 to 1978

(The closest free font I found was Boricua Regular.)

Proper font Univers:

The bottom tiny text in English/French doesn't change, it is Univers Pro 55 Roman. At one point the Russian/Cyrillic font changes from serif to sans-serif, but we don't care right now.

1979 to 1986

Font is also Univers:

Title text

ISO 4605-1978

I really can't figure out what the English text is...
The French is unmistakably Univers.

Notice the condensed form of "e" and "ss" (glass, mass). I can't find it in any Univers style...

Still, Univers 65 Bold and Zurich Bold are the closest. The "W" is too wide, and the "ss" and "e" are too wide...

ISO 4219-1979

I think it's closest to Univers Pro 65 Bold but preferably a bit less weight...

Body text

1972 to 1978

The body text is exactly the style of the title text... And I can't figure out what it is.

1978 to 1986

Probably the Univers 55 Roman style.

To enable layout add the document attribute:
:document-scheme: 1979.

[Intelligent2013]

ISO XSLT updated to using the font Univers as main font for layout version 1979.
(for testing purposes I used the fonts from https://font.download/font/univers
https://fontsgeek.com/fonts/univers-italic).

We can't add the Univers into metanorma-iso like this:

      def fonts_manifest
        {
          "Cambria" => nil,
          "Cambria Math" => nil,
          "Times New Roman" => nil,
          "Source Han Sans" => nil,
          "Source Han Sans Normal" => nil,
          "Courier New" => nil,
          "Inter" => nil,
          "Univers" => nil,
        }
      end

because the Univers font isn't free and not supported by fontist:

[fontist] 'Univers' font is not supported. Please report this issue at github.com/metanorma/metanorma/issues to report this issue.

So, the end-user is responsible for the purchase and font installation.
The fontist should find the installed font and pass it into the PDF generation via manifest file into mn2pdf. Therefore, we have to set the document attribute for each document with layout 1979:

:fonts: Univers

I'll add this info into blog post about ISO historical layouts.
