摘要:
An ink jet recording apparatus comprises a carriage movable in a given direction with a recording head which is detachably mountable on it and provided with discharge ports for discharging liquid. The apparatus is arranged to include a sensor for detecting the presence or absence of the carriage, the recording head, and at least one of the ink containers. This sensor is provided for the main body of the apparatus and positioned within the movable range of the carriage. With this arrangement, it is possible to simplify the structure required for detecting whether or not these vital elements for recording are installed without any auxiliary power-supply or memory means.

Whether or not a color image is present adjacent to a black image is discriminated. Whether the black image is formed using a black ink or a plurality of color inks C, M, and Y is determined in accordance with the discrimination result. When the black image is formed using the plurality of color inks, it is recorded using a repetitive pattern of two of C, M, and Y so as to prevent blurring with the color image, and to improve fixing characteristics by decreasing the total ejection amount.

An ink jet recording apparatus comprises a recording head adapted for ejecting at least two colors of ink, a discriminater for discriminating between character data and bit map data, and a controller for selecting a character data recording mode or a bit map data recording mode in accordance with a discrimination result by the discriminater. The controller controls an amount of ink ejection in the bit map data recording mode to be less than that in the character data recording mode.

A transfer recording medium comprising a substrate and a plurality of image forming elements bonded thereto by a binder is provided. The surface of each image forming element at least partially protrudes out of the binder. Such transfer recording medium may be prepared by applying the binder onto the substrate in a prescribed thickness, disposing the image forming elements in excess on the binder, and then removing the excess of the image forming elements. The thus prepared transfer recording medium provides an image having a high density and a faithfully reproducible color.

Disclosed are an apparatus for and a method of recording images on a recording medium by utilizing a transfer medium having a transfer layer whose transfer characteristics are caused to change by the application of a first energy and a second energy which differs from the first energy. The image recording apparatus includes a conveying device for conveying the transfer medium, a recording section disposed along the conveying path of the transfer medium conveyed by the conveying device, the recording section having a first energy applying device for applying the first energy to the transfer medium and a second energy applying device for applying the second energy to the transfer medium, a transfer section having a heating device and a pressure applying device used to transfer the image formed on the transfer medium in the recording section on the recording medium, and a fixing section for fixing the image transferred on the recording medium in the transfer section to the recording medium. The fixing section applies heat and pressure to the recording medium, and either of the heat and pressure or both of them is set to a value or values which is higher than that of the heat or pressure or both of them applied in the transferred section. The image recording method includes the steps of applying the first energy and the second energy to the transfer medium, transferring the image formed on the transfer medium by the energy applying step to the recording medium, and fixing the image transferred to the recording medium in the transfer step to the recording medium. Heat and pressure are applied to the recording medium in the fixing step, and either of the heat and pressure or both of them applied to the recording medium in the fixing step is set to a value or values which is higher than that of the heat or pressure or both of them employed in the transfer step.
摘要:
Each picture element is made to correspond to a plurality of dots and the ratios of printing energy corresponding to respective dots in each picture element are determined to correspond to respective tones. The heat accumulation state of a heat generating member corresponding to a picture element to be printed is detected from the tones of picture elements about the picture element to be printed for controlling the printing energy supplied to the heat generating members corresponding to respective dots of the picture image to be printed in accordance with the printing energy ratio and the detected state. With this method it is possible to provide a half tone print having uniform high quality regardless of the tone of a previous line and tones of surrounding picture elements.
摘要:
A printing method is shown in which printing quality is improved when superimposed thermal-transfer recording is performed. According to the present invention, at least one of a plurality of thermal-transfer media is made of a material of different thermal characteristics from the remaining media. Different thermal-transfer media thermal characteristics are obtained by changing the thickness, melting point or viscosity of the thermal-transfer ink on the thermal transfer media, or by changing the thickness, quality of material or density of the base material of the thermal-transfer media.
