摘要:
A method and apparatus for producing a document having human-readable content and a position identifying encoding pattern. A printer places text or other content onto a substrate, such as paper, and a filter material application system applies transparent filter material to at least a portion of that content to only modify the reflectivity of the content at a predetermined wavelength. Because the reflectivity of the position identifying encoding pattern remains unchanged, it is distinguishable from the content and can be read at the predetermined wavelength. The position identifying pattern can take a number of forms including a number of dots printed at predetermined positions on the substrate on an imaginary grid.

A method of applying content and a data encoding pattern 18 to a product 10 comprises: applying the content 14 to a substrate 12; modifying the reflectivity of the content 14 at a predetermined wavelength; and applying the pattern 18 to the product, wherein the method is such that the pattern can be distinguished from the content at the predetermined wavelength.

A product 100 having a data encoding pattern 108 printed on it, the pattern defining a grid having a grid spacing, wherein the grid spacing has discontinuities arranged to compensate for a mismatch between the resolution at which the pattern 108 is printed and a required value for the grid spacing, the discontinuities being irregularly spaced across the product.

摘要:
A method of printing a document containing a printed pattern of position identification pattern markings comprising: providing to a printer a set of print instructions which define the content of a document; generating at the printer a pattern using pattern information that is independent from the print instructions; and printing a document that comprises both the content and the pattern.

Automatic testing determines whether a proofing-file generator and receiver are in a common intranet. If so then the proofing file is automatically sent by a route that is substantially wholly within the intranet, and ideally peer-to-peer. If the generator and receiver are not in a common intranet, then preferably the file is sent by a conventional route through the Internet, preferably via a master server of the proofing service. The test preferably includes dynamically establishing IP addresses for the generator and receiver, and comparing the established IP addresses; however, consultation of a pretabulated listing is also possible.

In a process for the production of an aircraft stop by molding a composite material of resin and carbon fibers, a stack of pieces made of composite material, in which a metal piece will have been inserted, is draped by superposing layers of carbon fibers that are preimpregnated with resin, whereby the fibers are oriented so as to ensure maximum cohesion of the unit around the metal piece (4).
