Dot omission inspection method used in printing apparatus and the printing apparatus

A printing apparatus for forming an image by causing a liquid droplet to be landed on a medium, comprising:

• a plurality of nozzles for discharging a first ink and a second ink which are cured when irradiated with light as liquid droplets;
• a first light irradiating unit;
• a second light irradiating unit;
• and
• a control unit,
• wherein the first light irradiating unit irradiates the liquid droplets landed on the medium with light to provisionally cure the liquid droplets to prevent the liquid droplets from flowing,
• wherein the second light irradiating unit irradiates the liquid droplets landed on the medium with light to cure the liquid droplets so as to be fixed on the medium,
• wherein the control unit selectively performs a normal print process of forming an arbitrary image and an inspection print process of forming an inspection image as a detection object for a dot omission,
• wherein the normal print process includes:
• performing liquid droplet discharge of causing the liquid droplet of the first or second photo-curable ink to be landed on the medium;
• performing provisional curing of irradiating the liquid droplet landed on the medium using light from a first light source to provisionally cure the liquid droplet so as to suppress flowing of the liquid droplet;
• and
• performing main curing of irradiating the provisionally cured liquid droplet using light from a second light source to cure the provisionally cured liquid droplet so as to be fixed on the medium, and
• wherein, in the inspection print process, the provisional curing is not performed on the liquid droplet of the first ink landed on the medium by the liquid droplet discharge, and the liquid droplet of the second ink is landed by the liquid droplet discharge at the same position as the liquid droplet of the first ink which is not provisionally cured so as to mix the first ink and the second ink with each other.
