Logos
Various logos have traditionally be kept in the
directory /usr/local/shared/eps. For convenience, some
are now repeated here.
One is warned against the improper use of such logos, and, for completeness, directed to the University's brand resources website.
The (Encapsulated) PostScript files here are all hand-written, and can be edited with your favourite text editor to adjust aspects of their style. The PDF and SVG versions are generally machine-generated. Most of these were first created when EPS was the preferred format for such things, especially for inclusion with LaTeX. Today pdflatex, scribus and inkscape mean that PDF is usually more convenient, even if it is generally impossible to modify with a text editor. Instructions for conversion at the bottom of this page.
The TCM Group logo, as originally designed by Dr Matt Segall in the late 1990s. It is available as:
EPS (alter one line near the end to toggle the shadow)EPS (the same in white for use on dark backgrounds)
PDF (again editable to remove the shadow)
PDF (the same in white)
SVG (no shadow)
SVG (with shadow)
(N.B. If editing the PDF versions, one must not add or subtract the merest space.)
An eminent professor concluded that the Cavendish Crocodile as designed by Eric Gill was too fierce, so he created the TCM crocodile. It is said that this creature is little recognised outside of TCM, but it has certainly been well-known within TCM for thirty years.
EPS (editable to toggle the brick filling)
A hand-vectorised version of the crocodile, commissioned by Prof Kapitza, which Eric Gill carved onto the side of the old Mond Laboratory in honour of Lord Rutherford. The PostScript is highly customisable, with the text being removable, the level of detail being variable, and the bricks being removable. In general, the smaller the logo will appear, the less detail should be used - not a rule I have followed here.
EPS (with text)EPS (no text)
Sometimes a rampant crocodile is inconvenient. So this one is rotated. Being hand-vectorised, the bricks, a mere fill pattern, remain horizontal. Again the level of detail and fill is customisable.
EPS (with text)EPS (no text)
The University identifier with the text Cavendish Laboratory in the Sabon font. The text is flattened to lines and curves.
EPSEPS (white text for use on dark backgrounds)
The University shield. Again the PostScript is editable, with black and white versions available, as well as colour, as shown here.
EPS (colour)EPS (black and white, for the lazy who do not wish to edit the previous file)
Other Formats
PNG
For use on the web, pngs are more convenient than EPS or PDF. The above can be converted to pngs with commands such as:
eps2gif -pnga -res 200 crest.eps > crest.png
The res argument is the horizontal resolution, and I would
recommend using twice the value one intends to put in
the img tag to ensure that the image looks sharp on
smartphones and retina displays. This is how the images in this
page were created. Use png in place
of pnga if you do not want transparency.
For PDFs, then
epstopdf crest.epstend to suffice (or
ps2pdf for an alternative).
SVG
It seems generally best to convert to PDF and then use Inkscape to load the PDF and save as SVG.
JPEG
Don't even think about it. These sharp logos will look horrible if that happens to them.
