PROBLEM TO BE SOLVED: To provide an one-phase printing method without using urea, which is excellent in chromogenic property of reactive dye and is excellent in reproducibility and uniformity in printing. SOLUTION: When a printing colored size including an alkali agent, reactive dye and size and not including urea on a cellulose fiber-including material and subjecting it to drying and then to steaming, an aqueous solution having <=12 pH value and including at least one of a group consisting of neutral salts and carbonates is sprayed to the above material. The above alkali agent is at least one kind selected from a group consisting of sodium bicarbonate, potassium bicarbonate, sodium acetate, potassium acetate, sodium trichloroacetate, potassium trichloroacetate, sodium acetoacetate and sodium acetodicarboxylate.
