I would like to make tikz box with a letter (thumb index) longer (stretch it over the cropping edge), but I need to leave the position of the letter and placement of the box untouched.
Creation of the original box can be found in this answer.
Updated: working MWE included. MWE bellow illustrates A4 papersize, C5 layout. Currently thumb index is anchored to the edge of the paper, so that it is placed out of the printing area (C5). I need to placed the thumb to the original position (at the edge of the printing area), while ensure that the letter is correctly positioned and thumb indexed stretches over the edge. Original width of the thumbs is 0.5 cm and letter is centered inside.

\thumbwidthby setting\setlength{\thumbwidth}{\dimexpr(\csname Gm@layouthoffset\endcsname)+0.5cm}creates a box that stretches from the border of the paper across the cutting edge to 0.5 cm to the printed layout area. It remains to solve how to place the letter correctly. – chejnik Nov 26 '15 at 15:21\hspace{\dimexpr(\csname Gm@layouthoffset\endcsname)/2}at the start of the node label for the thumbs be what you need? – Torbjørn T.
