摘要:
Provided is a technology of embedding watermark data into an arbitrarily-shaped region by applying a wavelet transform. Prepared are: image data into which the watermark data is to be embedded; a shape map that defines the arbitrarily-shaped region into which the watermark data is to be embedded within the image data; and the watermark data. An SA-DWT processing unit uses the shape map to recognize a given region included in the arbitrarily-shaped region within the image data, and subjects image data in the given region to the wavelet transform. The wavelet transform causes the image data in the arbitrarily-shaped region to be divided into frequency bands, and a watermark data embedding unit embeds the watermark data into a frequency space of the image data generated by the dividing. An SA-IDWT processing unit subjects the resultant to an inverse wavelet transform, and watermark-embedded image data is generated.

An adhesive label includes a pressure-sensitive adhesive agent layer formed on one surface of a support. A non-adhesive heat-reactive layer is positioned above the adhesive agent layer and in which openings are formed by heating at a predetermined temperature or higher. An intermediate layer is positioned between the heat-reactive layer and the adhesive agent layer. The intermediate layer and the heat-reactive layer are each formed thinner than the adhesive agent layer. The intermediate layer facilitates the formation of the openings in the heat-reactive layer with good heat energy efficiency and allows the intermediate layer or the adhesive agent layer to be exposed through the openings.

Provided is an apparatus for producing a sheet material including: an RFID reader (11) for reading information from an RFID tag; a sheet supply unit (12) for supplying the sheet material (4) having a heat-sensitive printing layer on one surface of a sheet-type base material, and having a heat-sensitive adhesive layer on the other surface of the sheet-type base material; a printing unit (13) for performing printing on the heat-sensitive printing layer of the sheet material (4) supplied from the sheet supply unit (12); a thermal activation unit (15) for heating the heat-sensitive adhesive layer of the sheet material (4), which is printed by the printing unit (13), to develop an adhesive force of the heat-sensitive adhesive layer; and a control unit (16) for controlling the thermal activation unit (15) to develop the adhesive force in a predetermined area of the heat-sensitive adhesive layer other than an area facing the RFID tag so as to form an adhesive area to be attached to the article, and for controlling the printing unit (13) to print predetermined information on the heat-sensitive printing layer, based on the information read from the RFID tag by the RFID reader (11), thereby making it possible to match information of the tag with information printed on the sheet material with reliability, and to simply attach the tag to the article.
摘要:
To obtain large adhesive strength by forming openings with a sufficient size and high precision in a non-adhesive layer of an adhesive label, and exposing an adhesive agent layer through the openings, heat or a physical force is applied to a non-adhesive layer formed on an adhesive agent layer, which is made of a pressure-sensitive adhesive agent and provided on one surface of a support of an adhesive label, to form openings with respect to slits formed in the non-adhesive layer, and the adhesive agent layer is exposed through the openings.

An adhesive agent label includes an adhesive agent layer which is made of an adhesive agent and is formed on one surface of a support. A non-adhesive heat-reactive layer is positioned above the adhesive agent layer and has openings formed by heating at a predetermined temperature or higher. An intermediate layer is positioned between the heat-reactive layer and the adhesive agent layer. The intermediate layer and the heat-reactive layer are formed thinner than the adhesive agent layer. The intermediate layer facilitates the formation of the openings in the heat-reactive layer with good heat energy efficiency and allows the intermediate layer or adhesive agent layer to be exposed through the openings.

A product history management apparatus issues to label issuing apparatuses identification information to be printed on a label affixed on a product produced in production steps from raw material production to final product production. An identification information receiving device receives from a label issuing apparatus associated with one of the production steps information printed on a label affixed in a production step immediately preceding the one production step. An identification information transmitting device issues new identification information relative to the received identification information and transmits to the label issuing apparatus associated with the one production step the issued identification information. An identification information storage device stores the received identification information in the production step immediately preceding the one production step in association with the issued and transmitted new identification information.

When first print information is input, a print length thereof is calculated so as to calculate a length of a double-sided printed material 1 to be finally produced. Then, print information blocks 2 to be printed on a back surface of the recording medium is selected. The print information blocks 2 are selected according to a priority thereof, and a single print information block 2 to be selected last is selected, based on the length of the double-sided printed material, so that all the margins have the same length within a predetermined allowable range when the selected print information blocks 2 are sequentially arranged to be printed on the back surface. After the second print information is thus determined, the first print information is printed on the front surface of the recording medium and is cut by a cutter unit, and then the second print information is printed on the back surface thereof.

Provided is a printing system, a printer, and a printing method with which decoding of digital watermarks is possible at a high ratio while ensuring visibility of human-readable information even when the human-readable information is superimposed on the digital watermarks before printing. In a URL server (2), a conversion unit (22) converts predetermined information into digital watermark information represented by a plurality of dots in an on state among dots arranged in a matrix manner, a processing unit (23) generates thinned-out digital watermark information by processing a part of the plurality of dots in the on state into dots in an off state so that at least dots that are successively arranged in a vertical or horizontal direction and are in the on state are not present in the digital watermark information, and a communication control unit (24) transmits the thinned-out digital watermark information to a printer (3). The printer (3) prints the thinned-out digital watermark information and the human-readable information in a superimposed manner.

A positive resist composition that includes a resin component (A), which contains acid dissociable, dissolution inhibiting groups and exhibits increased alkali solubility under the action of acid, and an acid generator component (B) that generates acid on exposure, wherein the resin component (A) is a copolymer (A1) containing a first structural unit (a1) derived from hydroxystyrene and a second structural unit (a2) derived from a (meth)acrylate ester having an alcoholic hydroxyl group, in which a portion of the hydroxyl groups of the structural units (a1) and the alcoholic hydroxyl groups of the structural units (a2) have been protected with the acid dissociable, dissolution inhibiting groups; and either the acid generator component (B) includes a diazomethane-based acid generator and an onium salt-based acid generator; or the composition further contains a compound, which contains at least one acid dissociable, dissolution inhibiting group, and generates an organic carboxylic acid under the action of acid generated from the component (B).
摘要:
The invention discloses an improvement in the photo-lithographic patterning process of a photoresist layer in the manufacture of semiconductor devices in which occurrence of defects in the patterned resist layer can be greatly suppressed resulting in increased reliability of the semiconductor devices and productivity thereof. The improvement can be accomplished by using a chemical-amplification positive-working photoresist composition which exhibits a rate of film thickness reduction in the range from 0.09 to 1.0 nm/second when the photoresist layer before light-exposure is kept in a 2.38% aqueous solution of tetramethylammonium hydroxide at 23° C. to dissolve away the resist layer.
