Printing method, printing apparatus, and printed matter

A printing apparatus, comprising:

• a processing fluid applying unit configured to apply a processing fluid containing a multivalent metal salt to a print medium;
• a white ink applying unit configured to apply a white ink containing a white coloring material and water to form a white ink layer;
• and
• a non-white ink applying unit configured to apply a non-white ink containing a non-white coloring material and water to the white ink layer after securing a time interval of 0.5 seconds or longer after the white ink is applied without performing drying with a drying unit after the white ink is applied,
• wherein the print medium has a Cobb water absorption of 20 g/m2 or greater but 75 g/m2 or less when contacted with water for 120 seconds, where the Cobb water absorption is stipulated by JIS-P8140.

A printed matter, comprising:

• a print medium;
• a processing fluid layer on the print medium, where the processing fluid layer contains a multivalent metal salt;
• a white ink layer on the processing fluid layer, where the white ink layer contains a white coloring material;
• and
• a non-white ink layer on the white ink layer, where the non-white ink layer contains a non-white coloring material,
• wherein the print medium has a Cobb water absorption of 20 g/m2 or greater but 75 g/m2 or less when contacted with water for 120 seconds, where the Cobb water absorption is stipulated by JIS-P8140.
