Hallo David, and thank you for your suggestions. I have now found the
following :
1) The primary cause of the displacement is the PDF/X-1A:2003 specials --
remove these, and the page returns to its normal vertical position, but shifted
outwards (leftwards) somewhat;
2) The use of \usepackage {color} within e-plain's \beginpackages ...
\endpackages; in TeX Live 2016, this makes the page size considerably wider,
IFF the PDF/X-1A specials are not emitted.
The displacement is visible both in TeXworks viewer and in Adobe Acrobat.
I think what you are seeing is due to the /CropBox settings.
A PDF viewer shows the contents of the cropped area,
scaling to fill either the width or height or both.
There are 2 kinds of test that you can do.
1. Print a few pages of your document, once with the \specials, once without.
Is there any difference in the position of your content on the printed page?
2. Vary the numbers in /CropBox [ a b c d ] ;
such that (a,b) is bottom-left and (c,d) is top-right corners of a
rectangle.
Values such as [ 200 200 300 300 ] should crop to a small-ish portion of a
page,
which is then scaled up to fit your window-size.
Observe the value of your browser’s scaling factor.
With different values of [ a b c d ] you can simulate vertical and
horizontal shifts,
to a small extent, according to how much smaller the /CropBox is, compared to
the /MediaBox.
Does this interpretation agree with what you observe?
A4 is indeed the default in both, and the difference between A4 and letter is
only 3/4", whereas it appears to require a 1" correction ...
