Abstract: The invention relates to a device for printing by transfer onto a print support (10) comprising at least one blanket (30) driven in a sequential relative movement past a magazine (50) conveying the print supports (10), in which device the blanket (30) has a surface area greater than that of the print support (10), the device further comprising digital printing means (20) which print by spraying ink onto this blanket (30) over a variable area equal to that of the print support (10).

Abstract: The present invention relates to an automated polymer synthesis apparatus for synthesizing a polymer chain onto a solid substrates by sequentially adding polymer building blocks as well as to a method for synthesizing polymers on solid substrates by sequentially reacting polymer building blocks with reactive groups. The invention further relates to a biochip comprising a solid substrate with reactive groups where biomolecules are attached to and the remaining reactive groups are transformed into chemically inert species.

Abstract: The invention relates to a fluid supply assembly for a device, particularly a printing machine. The assembly includes a lower base and is of the type in which the fluid is conditioned in an upper container which is intended to be connected to a fill opening in the base by a coupling. In order to mount the coupling on the base, the coupling is moved linearly along a vertical assembly axis and then pivoted around the assembly axis. The coupling has at least one keying pin which is received in a complementary groove in one face of the base when the coupling is being moved linearly. The invention also relates to a printing machine containing one such assembly.

Abstract: A a color ink-jet printer has at least four ink cartridges each containing one basic color selected from among yellow, magenta, cyan and black, and at least one additional cartridge containing a basic pale color ink. A processor receives a printing order containing data concerning the requested color and/or the number and color of the ink droplets to be deposited on one another at a specific location of a selected printing substrate. The processor includes an optimizing mode capable of matching the requested color and/or the required number and color of droplets to be superimposed to obtain a selected color at a given pixel with an equivalent color and/or an equivalent number and/or color of droplets to be superimposed to obtain a substantially equivalent and satisfactory color rendering in conformity with the human eye sensory response. The thus-determined equivalent color and/or the equivalent number and color of droplets to be superimposed is applied to the printer for each printing order received.
