Abstract: An ejection liquid capable of being stably ejected based on a system using thermal energy even if the liquid contains at least one selected from the group consisting of proteins and peptides, and a method and an apparatus for ejecting the liquid containing at least one selected from the group consisting of proteins and peptides using this system are provided. The applicability of the liquid for use in an inkjet system using thermal energy is improved by adding at least one selected from the group consisting of amino acids and salts thereof and a surfactant to an aqueous solution containing at least one selected from the group consisting of proteins and peptides.

Abstract: A method for enforcing a distribution policy associated with an electronic document comprising the steps of: sending the document to an output device; determining said distribution policy associated with said document; instructing a marking module to embed a marking indicating at least the existence of said distribution policy on an output form of said electronic document produced by said output device, said marking being readable to enforce said associated marking policy.

Abstract: A sheet feeding device is adapted to feed a recording medium including a first medium provided as a cut-sheet form and a second medium provided as a rolled-sheet form to a recording section at which a recording operation is performed with respect to the recording medium, by ejecting ink droplets thereto. A first sheet feeder is operable to feed the first medium stacked thereon to the recording section. A second sheet feeder is adapted to be detachably attached the first sheet feeder, and operable to feed the second medium to the recording section.

Abstract: This invention relates to an inkjet printing device of a franking machine intended to print postal indicia on a mail piece to be franked, displaced with respect to this device in a direction of displacement, the postal indicia comprising at least an amount of franking, a date of deposit and an authentication code and the printing device comprising, on the one hand, a plurality of nozzles for ejecting ink droplets, disposed in two rows extending transversely to the direction of displacement, these two rows of nozzles being spaced apart from each other by a distance in this direction and, on the other hand, a control means for selectively controlling the ejection of these ink droplets as a function of the postal indicia to be printed, said control means being arranged so that, during printing, each of the critical postal data such as the amount of franking, the date of deposit or the authentication code, is printed from one row of nozzles.

Abstract: A fluorescent substance of the following general formula:

Abstract: There is provided an image printing method and device which is capable of easily printing a bar code image having colors conforming to a bar code print quality standard. A bar code pattern defining the arrangement of bars of two kinds in a bar code is set. The bars of two kinds include at least one bar of a first kind and at least one bar of a second kind. The at least one bar of the first kind are different in optical reflectance from the at least one bar of the second kind. A first bar color is set which defines a printing color of the at least one bar of the first kind. A second bar color is set which defines a printing color of the at least one bar of the second kind, based on a predetermined bar code print quality standard which defines conditions concerning the optical reflectance of the bars of two kinds, such that a combination of the first bar color and the second bar color conforms to the predetermined bar code print quality standard.

Abstract: Postage indicia are printed on mail items using an ink having a characteristic such that the ink is rendered invisible when subjected to light or light and heat of sufficient intensity. When an attempt is made to copy the imprint of a postage indicia on a mail item for which proper accounting has been effected the imprint is subjected to a butst of light or light and heat and the ink becomes invisible and prevents copying of the imprint. The imprint of the postage indicium may overly and obscure a void mark which becomes visible and is copied in the event of attempting to copy the original authentic postage indicium.

Abstract: A method of identifying a franking machine used to print franking impressions is disclosed. Ink used by the franking machine contains an identification tag unique to each franking machine, or to a group of franking machines, and the impression printed by the franking machine is sensed to determine the identity of the tag and hence to determine the identity of the franking machine used to print the impression. The tag may be chemically unique or may be physically unique. The physically unique tag may have a unique shape or size or may bear a unique marking.

Abstract: A substantially flat paper article or product is marked by applying thereto a luminophore. In order for the thus produced markings to remain discernible even if the paper article constitutes a component or part in a collation or composite of such paper articles, the markings are applied to at least one location of a marginal region including the contiguous edge of the paper article. This marking method can be used to monitor the completeness of an end product manufactured by collating a plurality of different paper articles.
