摘要:
A method for printing on both sides of a roll sheet including superimposing and pressing a thermal transfer sheet and the roll sheet between a platen roller and a thermal head so that the bottom surface of the thermal transfer sheet touches the top surface of the roll sheet and the bottom surface of the roll sheet touches the platen roller, and printing an image on the top surface of the roll sheet while conveying the sheets; and superimposing and pressing a thermal transfer sheet and the roll sheet between a platen roller and a thermal head so that the top surface of the thermal transfer sheet touches the bottom surface of the roll sheet and the top surface of the roll sheet touches the platen roller, and printing an image on the bottom surface of the roll sheet while conveying the sheets.

摘要:
A printing head for an impulse jet type ink-jet printing apparatus which includes a plurality of nozzles supplied with ink from a common ink chamber through ink flow channels and pressure chambers which are substantially perpendicular to the nozzles. Piezoelectric-crystal elements are disposed in each pressure chamber and have a length to width ratio not less than 2 to 1 and not greater than 20 to 1.
摘要:
An image recording apparatus wherein a plurality of laser beams are scanned on a color photosensitive material by an optical deflecting device, the laser beams are detected by beam detecting devices, and record starting timings for the laser beams are controlled on the basis of detection signals provided by the detecting devices so that respective record positions of the laser beams are the same.
摘要:
An ink jet printer wherein a mechanical vibration is applied by an electromechanical transducer secured to a printing head to the ink in a nozzle and a pressure chamber of the printing head when the ink jet printer is not in a printing operation state, so that an ink flow is formed in the ink passage within the period of time including the mechanical vibrating operation or after the completion of the mechanical vibrating operation. The electromechanical transducer is used when droplets are jetted out. An electromechanical transducer which is brought into contact with the printing head only when the mechanical vibration is generated can be employed. The nozzle can be covered with a liquid within the period of time including the whole of the mechanical vibrating operation.
摘要:
There is described an image-recording medium and an image-reading method, which make it possible to improve reading accuracy of information by avoiding duplication of an optical variable image with the information. The image-recording medium includes a substrate, an image-receiving layer provided on the substrate and an optical variable layer provided on the substrate, wherein at least a part of the optical variable layer includes an optical variable image, and the optical variable image is formed in a manner such that the optical variable image, overlapping with an image recorded on the image-receiving layer, emerges in a first direction, while the optical variable image, overlapping with an image recorded on the image-receiving layer, does not emerge in a second direction.

A photographic image-bearing recording member and a manufacturing method of it are disclosed. The recording member comprisesa support,a thermoplastic resin layer bearing a photographic image, which is provided on a surface of said support, anda protective layer comprising a radiation setting composition and being set with irradation of an actinic radiation, which is provided at a outermost position of the side of the support on which said thermoplastic layer is provided. Symbols or characters may be further beared in the thermoplastic layer. The symbols and characters are preferably formed on the themopastic layer by the heat-transfer printing method.
摘要:
An ink jet printing device including a printing head having a nozzle through which ink can be ejected. The head includes an internal chamber ink and ink ejection is caused by internal pressure pulses. The internal chamber is formed in part by a deformable diaphragm which prevents extreme ambient temperature variations from causing damaging liquid pressure fluctuations.
