A mass produced absorbent article having an image of a quality that is commercially acceptable. The image is produced by ink jet printheads applying ink to a web moving at high speed under the jets in the course of manufacturing the article. The image is printed at low resolution but is characterized in part by a higher coverage area ratio and brightness.

Absorbent article with high quality ink jet image produced at line speed

Provided is a recording medium of a multi-layered structure comprising a base layer and a surface layer provided on at least one side of the base layer, wherein the base layer is mainly composed of fibrous material and the surface layer comprises an alumina hydrate of a boehmite structure incorporated in the fibrous material.

Recording medium, and method for producing image using the same

An ink jet recording medium is disclosed, comprising a coating formed on at least one surface of a substrate, characterized in that said substrate has an apparent density of 0.60 to less than 0.75 g/cm3 and a Steckigt sizing degree of 2 to 18 seconds and the coating is formed by applying a coating agent containing a white pigment, of which the BET specific surface is 100 to 400 m2 /g at a rate in the range of 2 to 10 g/m2. An ink jet recording method is also disclosed, characterized in that recording is performed using water-color ink, of which the surface tension at 20° C. is 40 dyne/cm, on an ink jet recording medium.

Ink jet recording medium and recording method

The printing paper can be formed by applying a slight amount of paint including a white pigment having a given BET specific surface area onto at least one side surface of base paper having a given apparent density. Also, according to the printing paper, in a time T=L/S to be determined by the shortest inter-nozzle distance L of different colors of a multi-color ink-jet printer and a printing paper/head relative moving speed S, the ink absorbing capacity V of the printing paper according to a blister method satisfies the following equation: V≧2ax2 /(0.0254)2 (where a represents an amount of ink drop to be jetted out from a nozzle, and x represents definition). The present ink-jet printing method uses the above-mentioned printing paper.

The invention provides a full-breadth stamping device. The outer part of the full-breadth stamping device comprises a paper inlet, a paper outlet and a casing, and the inner part of the full-breadth stamping device comprises a X-axis direction moving component, a Y-axis direction moving component and a stamping mechanism, wherein the X-axis direction moving component is used for detecting whether paper enters the paper inlet and driving the paper to move in the X-axis direction when paper entering the paper inlet is detected; the Y-axis direction moving component is used for driving the stamping mechanism to move in the Y-axis direction after the paper moves to a preset X-axis position; the stamping mechanism is used for stamping after the paper moves to a preset Y-axis position. According to the full-breadth stamping device, the stamping mechanism can realize the full-breadth stamping function of paper in the X-axis and Y-axis directions; a channel of the stamping device adopts a unidirectional imbricated design, which can effectively prevent paper from being stuck in the channel, and is suitable for paper of various specifications such as A4 and B4; besides, a stamp changing mechanism adopts a hand-twisting type detachable design, and has the characteristic of the maintenance of rapid stamp changing.

Full-breadth stamping device

PURPOSE:To contrive to enhance efficiency and enable to affix a stamp of a serial number accurately on a predetermined position of a paper, by providing a paper-supplying mechanism, a stamping table, a stamping part, a guiding and positioning mechanism for the stamping part, a driving mechanism for the stamping table and a paper- discharging mechanism. CONSTITUTION:The papers 2 are set into a cassette 1, and the positions in X-and Y- directions of the stamping part S are fixed by tightening thumb screws 32, 41. Thereafter, a starting buttom is depressed, whereby a main motor 8 is started, and the uppermost paper 2 is fed out from the cassette 1 onto the stamping table D by the paper- supplying mechanism M1. When the leading end of the paper is detected by a detector 15, feeding of the paper is stopped. Then, an air cylinder 20 is operated to stretch a piston rod 20a, whereby a slidable block 23 is lowered as one body with the stamping part S, and a contact plate 13 is brought into contact with the paper. Starting from this condition, the piston rod 20a is further stretched, whereby numeral types 11 are protruded through a type window 13a to affix a stamp of a serial number on the paper. Thereafter, the block 23 is slidden upward together with the stamping part S, and is returned to the initial position. The paper thus stamped is fed between a paper-discharging roller 50 and a driven roller 51, and is discharged into a paper-discharging tray 54.
