VERTICAL POSITIONING OF SYMBOLS AND PATCHES ALONGSIDE TILES
3.19 The general rule, as illustrated in figure 3-9, is that a symbol is centred vertically alongside the tiles of a legend and then moved upwards by 0.5sw. On a simple sign this has the effect of centring the symbol vertically between the top and bottom borders whilst maintaining the correct vertical spacing for the legend tiles. The minimum vertical space between the symbol and the sign borders is 2.5 sw. On signs where close proximity to a border may not be a consideration, this rule has the effect of producing a more balanced appearance by taking account of the space on the tiles beneath the baseline of the letters.
20 When a patched route number is placed alongside a single line legend the rule given in para 3.19 does not apply. The tiles of both the place name and route number must align vertically. If the legend block is adjacent to both the top and bottom border of a sign or edge of a panel, then the patch will be centred on the sign or panel with a minimum vertical gap of 2.5 sw. An example is shown in figure 3-10. When a patched route number is placed alongside a two line legend it is treated the same as a symbol in terms of vertical alignment. An example is shown in figure 3-11.
