Printing apparatus and color adjusting method

A color adjusting method for use in a printer to print a video signal using printing media, the method comprising steps of:

• storing a plurality of data different from each other in a value on which a color appearance characteristic of the printing media depends in an updateable table;
• converting, using the video signal, an image composed of R, G, and B video signals based on the video signal to complementary-color images to be output in a number of columns;
• printing the set of complementary-color images as an output from the converting step using the printing media;
• selecting a desired one of the set of complementary-color images as printed on printing paper at the printing step;
• and
• adjusting colors of an output image according to the image selected at the selecting step;
• wherein the step of selecting a desired one of the set of complementary-color images as printed on printing paper, comprises the steps of,
• selecting, by a user, an important area of a subject image;
• creating a plurality of test images, each test image being created by applying an individual one of the data to the important area of the subject image;
• printing the test images;
• outputting a set of markers, each marker corresponding to one of the printed test images and comprising a graphical representation of the corresponding printed test image but not derived from the test image or subject image, on a display screen;
• and
• retrieving a user selection of the markers.
