The Bank of Ireland reintroduced colour on its banknotes with Series E in 1864 with the listing of all of the bank's branches in red on its notes, as well as the date and serial numbers. Colour had previously briefly been used to a small degree in the 1790s. The new Series E multibranch banknotes continue the iconic design of a row of mercury heads and twin statues of Hibernia that the bank introduced in 1838.
Large sized banknotes. Uniface. All denominations are of a similar size. Head Office DUBLIN.
Watermark: bank’s name in a curve with a year of manufacture inside the curve.
Banknotes printed on watermarked paper. All branches of the bank listed in red several lines on each banknote. The number of branches listed increases as time goes on. There are several known signature varieties, and at least one further unknown signature.
There are four Types by major design variation for Series E banknotes, which divide into several variations by signature. Relatively little is known about Series E notes prior to Type D (1908) as the notes are quite scarce. It is likely that several other as yet unrecorded signatures exist on notes of Types A to C.

Observation of printing plates in the bank's archives reveals that all Bank of Ireland multibranch notes were printed 2 up on a plate with a large watermark in the centre of each note. Plate letters indicated the position of the notes on the plate. From observation, left side notes had odd plate numbers, and right side notes had even plate numbers.
Detail of the water mark on a 1914 One Pound note shows the text 'Bank of Ireland' in an oval at the centre of the note. There is often a number visible in the centre of the watermark. Sometimes this is a year, presumed to be the year of manufacture of the paper.
