A light emitting device includes a semiconductor nanocrystal in a layer. The layer can be a monolayer of semiconductor nanocrystals. The monolayer can form a pattern on a substrate.

There is described a combined printing press (10) for the production of security documents, in particular banknotes, comprising a screen printing group (3) and a numbering group (4) adapted to process printed substrates in the form of individual sheets or successive portions of a continuous web. The screen printing group (3) is located upstream of the numbering group (4) and comprises at least one screen printing unit (32-33) designed to print a pattern of optically-variable ink, which optically-variable ink contains flakes that can be oriented by means of a magnetic field. The screen printing group further comprises a magnetic unit (36) located downstream of the screen printing unit (32-33), which magnetic unit (36) is designed to magnetically induce an optically-variable effect in the pattern of optically-variable ink applied by the screen printing unit (32-33) prior to drying/curing of the optically-variable ink. The screen printing group (3) further comprises at least one drying/curing unit (37) designed to dry/cure the pattern of optically-variable ink in which the optically-variable effect has been induced by the magnetic unit (36), prior to transfer of the printed substrates to the numbering group (4).

A printing method is provided, in which character sizes are enlarged gradually as going from a lower portion to an upper portion of a printing surface which may be a page of a book or an article region on which an article of a newspaper is printed. The longitudinal size (height) of characters at a lowest portion in each page of the book or in the article region is k times larger than a longitudinal size of characters at a highest portion, and wherein a value of k is about 1.281.79. The horizontal size (width) of characters at the lowest portion in each page of the book or in the article region is k times larger than a longitudinal size of characters at a highest portion, and wherein a value of k is about 0.71.0 times larger than the k.
