摘要:
In order to print an image at a high speed without using any large-capacity power supply unit, the image to be printed is segmented into grayscale-specific areas before printing, and the cumulative number of printing elements required to print the respective grayscale-specific areas is counted to predict a necessary power. On the basis of the prediction result, the image is then printed by selecting the highest convey speed from convey speeds at which upper limit powers used and rated average power consumption are determined. This makes it possible to provide an image printing method and apparatus which can realize high-speed image printing.
摘要:
There are disclosed a printing method and apparatus which can prevent an overcoat layer formed on the surface of a printing medium for the purpose of protecting a printed image from being torn off or peeling from the printing medium so that an overcoat agent will not become a contaminant and stain a print in the printing apparatus, cause image print abnormality, or become fine or powder dust in the environment. This apparatus prints an image on a printing medium having perforations that allow easy cutoff of margin portions by applying ink to the printing medium across the perforations, and forms a protection layer on the printing medium on which the image has been formed by transferring a protection agent avoiding the perforation portions.
摘要:
A recording apparatus, which uses an ink sheet having ink of plural colors coated sequentially thereon and transferring ink to a recording medium for recording in accordance with image data, is capable of recording on a plurality of recording media having different sizes, at the same time, being capable of using selectively plural ink sheets each corresponding to each of the plural recording media of different sizes. This recording apparatus comprises a device for detecting the size of a recording medium to detect the size of the recording medium to be used for recording; a device for detecting the size of an ink sheet to detect the size of a recording medium corresponding to the ink sheet to be used for recording; and controlling a device to control the recording operation in accordance with the size of the detected recording medium and the size of the recording medium corresponding to the detected ink sheet. With these devices thus arranged, it is made possible to record without recording improperly any smaller images that may be unfit for the size of the recording sheet or staining the platen and others in the interior of the apparatus even when the recording medium and the ink sheet installed thereon are different in its sizes or the user does not designate the size of the recording medium to be used.

摘要:
A plurality of image data to print a panorama image is selected from a plurality of image data photographed by a digital camera. The selected plurality of image data is read out and a panorama image composition processing is executed. The panorama image is printed on the basis of the image data which was panorama image composition processed and is printed as a panorama image without transmitting through a personal computer.
摘要:
A liquid accommodating container having a configuration that allows ink to be substantially used up, does not require an increase in size or a complicated construction, and can be fabricated at lower costs. The container includes an ink chamber for holding ink and having an upper air layer. A second chamber is provided in the upper air layer. A partition divides the second chamber into an ink absorber chamber that accommodates an ink absorber and a sub ink chamber for storing a small amount of ink. A third chamber defines a space between the atmosphere and the ink absorber. An upper portion of the sub ink chamber adjacent to the ink chamber is open so as to provide communication between the upper air layer and the atmosphere through the intermediary of the sub ink chamber and the ink absorber chamber in this order. An atmosphere communicating hole is defined. A print head that discharges ink of the ink chamber is provided at the bottom of the container.
摘要:
A residual ink detection mechanism for detecting the amount of residual ink within an ink container of an ink jet printer is disclosed wherein the ink container comprises a flexible bag, and electrodes are provided at least at opposite positions of this bag to constitute a capacitor, so that the amount of residual ink within the ink container may be detected by detecting the electrostatic capacity between these paired electrodes.
摘要:
A recording apparatus in which ink flows out from the end of a recording head to effect recording on a recording medium, has in a portion of an ink supply path leading from an ink container to the recording head a filter substantially parallel to the direction of liquid flow in the supply path and having a number of minute communication bores.
