摘要： In a printing apparatus improvement of drying ability and reduction of consumed power are concurrently achieved by improving the efficiency of drying ink. More concretely, hot air is blown onto a print medium printed by ink, and a portion of the blown hot air is recovered and blown again. Before the hot air is blown, the print medium is heated by a preheating unit, making it higher than the dew point temperature of the blown hot air.

摘要： A method of adjusting bidirectional registration to reduce negative effects on the image such as “banding” even if bidirectional registration includes a slight amount of displacement is provided. For that purpose, correction is applied to a first adjustment value for adjusting a bidirectional registration displacement in response to an extent of inclination of a printing head to obtain a second adjustment value. Then a bidirectional printing is performed with timing adjusted on the basis of the second adjustment value. As a result of that, even if there is a slight variation in an adjustment value of the bidirectional registration and the inclination of the printing head, the banding generated by this can be reduced as much as possible.

摘要： In an image printing apparatus for printing an image by combining dots of a plurality of sizes, a banding problem attributable to variations in conveying operation, and a temperature rise of a print head with an increase of the number of ejections are solved with a relatively simple configuration. To this end, a combination of dots of a plurality of sizes is assigned to each of pixels expressed at a plurality level of density. In this assignment, a dot larger than a pitch of an image resolution is preferentially allocated to a pixel having a density level higher than that to which one dot smaller than the pitch of the image resolution is allocated.

摘要： Provided is a temperature detection method capable of more accurately acquiring an environmental temperature and more accurately correcting temperature detection of a printhead. In a printing apparatus to which this method is applied, a previous printing time when the printhead has performed a printing operation is stored in a nonvolatile memory. The current time is acquired using a timer which always performs a time counting operation by power supply from an auxiliary power supply capable of supplying power independently of a main power supply that supplies power for performing the printing operation by the printing apparatus. A time elapsed after the previous printing time is calculated on the basis of the current time and previous printing time. The elapsed time and a predetermined time are compared. The temperature is measured using a sensor arranged in at least one of the printing apparatus and the printhead in accordance with the comparison result. A temperature is updated on the basis of the measured temperature.

摘要： A contamination of a printing medium caused by ink mist or the like is suppressed, which may scatter or float in an apparatus when margin-less printing is carried out in an ink jet printer. When margin-less printing for an edge of a printing medium P is performed, a predetermined edge area {circle around (1)} is printed using a smaller number of ejection openings during one scanning operation than that used for other areas {circle around (2)} and {circle around (3)}, while taking transportation errors relating to this end into consideration. This reduces the amount of ink mist resulting from ink ejected out of the edge of the printing medium during one scanning operation.

摘要： An inkjet recording apparatus includes a recording head having a nozzle array of plural nozzles capable of discharging ink. The inkjet recording apparatus performs a scanning/recording operation for forming an image on a recording medium by shifting the recording head in a main scanning direction. The inkjet recording apparatus repeatedly perform the scanning/recording operation and a recording medium conveying operation. The inkjet recording apparatus sets a recording position correction amount for each section of the nozzle array based on information relating to the inclination, so that a recording position correction amount in a forward scanning operation is different from a recording position correction amount in a backward scanning operation.

摘要： When recording a gradation pixel by performing pseudo-halftone processing, the occurrence of unevenness in the density in the recorded image is suppressed. For that purpose, when recording a pseudo-halftone image using dot patterns, a dot-pattern table storing a plurality of different dot patterns is provided for each gradation value. One dot-pattern table is selected from N dot-pattern tables based on gradation-value information for each pixel. One dot pattern is selected from the selected dot-pattern table, based on position information indicated by the pixel, and recording is performed using the selected dot pattern. It is thereby possible to prevent the concentrated use of a particular nozzle of a recording head, and suppress the occurrence of unevenness in the density due to characteristics of the specific nozzle.
