Embodiment Construction

[0045] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. In the present invention, "idle scan" means a scanning operation of the print head performed without ejecting ink from the print head for printing purposes.

[0046] 1. Basic structure

[0047] 1.1 Overview of Printing System

[0048] FIG. 1 is a diagram for explaining the flow of processing image data in a printing system employing an embodiment of the present invention. The printing system J0011 includes a host device J0012 that generates image data representing an image to be printed, and sets a user interface (UI) for generating image data and the like. In addition, the printing system J0011 includes a printing device J0013 for printing an image on a printing medium based on image data generated by the host device J0012.

[0049] Printing device J0013 uses cyan (C), light cyan (Lc), magenta (M), light magenta (Lm), yellow (Y), red (R), gr...

Abstract

The present invention provides an ink jet printing apparatus and a method for controlling an ink jet printing apparatus which can shorten the stirring duration without losing any stirring effect by stirring ink at a required time to only a required level and still perform a printing operation with no image impairments. By a reciprocal movement of the carriage according to a mode during a non-printing operation excluding a print operation that is accompanied by a reciprocal movement of the carriage, ink in an ink tank is stirred. The stir mode is set according to the color of the ink in the ink tank mounted on the carriage.

Description

technical field [0001] The present invention relates to an inkjet printing apparatus that prints an image by moving a carriage on which an ink tank can be mounted and a method for controlling the inkjet printing apparatus. Background technique [0002] Pigment inks have higher weatherability than dye inks, so pigment inks have been used in inkjet printing devices in recent years. Weather resistance includes light fastness, ozone resistance and water resistance. The pigment particles contained in pigment inks do not easily lose their color saturation due to decomposition by light or ozone, and their colors do not fade due to long-term exposure to light or ozone. Therefore, when used to print outdoor advertisements and long-term display exhibits, or print pictures that need to be preserved for a long time, pigment inks show their unique and excellent performance. Also, since pigment particles are not water-soluble, pigment inks have better water resistance than dye inks. Be...
