    Abstract: There are provided a printing apparatus and printing method capable of achieving high?quality printing by fine ink droplets, and collecting unwanted ink droplets. According to the method, ink droplets discharged from a printhead are negatively charged by the negative ions in printing. A printing medium is charged positively opposite to the polarity of ink droplets. By the electrostatic force, discharged ink droplets travel toward the printing medium, and the amount of ink droplets attached to the printing medium is increased. In addition, an ink mist collecting unit having a positive electrode is employed to collect floating ink mist.

    Abstract: There are provided a printing apparatus and printing method capable of collecting unwanted ink mist and achieving high-quality printing by fine ink droplets. According to the method, the charges of a printing medium are removed prior to printing, and an ink mist collecting unit having an electrode of a positive polarity is employed. Floating ink mist is collected such that ink mist generated from discharged ink droplets and negatively charged is moved toward the ink mist collecting unit by the electrostatic force.

    Abstract: A check pattern for a registration adjustment under low resolution condition of 600 dpi x 600 dpi at substantially central portion of a printing medium is printed. After performing the registration adjustment based on the printed pattern, the check pattern is printed under high resolution condition of 1200 dpi x 600 dpi at a position not causing interference with the former check pattern. On a basis of this, the registration adjustment is again performed. By this, the registration adjustment in high precision printing can be performed easily. Also, necessary two check patterns can be printed on a single printing medium to permit lowering of cost concerning printing medium to be used in check pattern printing.

    Abstract: In the present invention, upon printing of an image on a printing medium by ejecting an ink for a treatment liquid ejected on the printing medium, by scanning the printing medium, a number of scan for the same region of the printing medium is judged, and ejection from a printing head is performed by variably setting the ejection amount of the treatment liquid in one scan by varying ratio of dots to be ejected versus all dots on the printing medium. Thus, deposition of mist or rebounded droplets on an ejection surface of an ink ejecting portion of the printing head can be avoided. By the present invention, pollution of the ejection surface of the printing head is avoided and thus reliability of ejection of the printing head is maintained.
