Printing system

A printing system that prints an image by ejecting a liquid onto a substrate, the printing system comprising:

• a transport device that transports the substrate along a transport path;
• a first ejection device that ejects a first liquid onto the substrate based on first image data;
• a first measurement device that measures a state of the substrate;
• a first drying device that dries the liquid ejected onto the substrate;
• a second measurement device that measures the state of the substrate;
• a second ejection device that ejects a second liquid onto the substrate based on second image data;
• a second drying device that dries the liquid ejected onto the substrate;
• a third measurement device that measures the state of the substrate;
• at least one processor;
• and
• at least one memory that stores an instruction to be executed by the at least one processor,
• wherein the transport device transports the substrate in an order of the first ejection device, the first measurement device, the first drying device, the second measurement device, the second drying device, and the third measurement device,
• the at least one processor
• calculates a first correction value for correcting the first image data based on a measurement result of the first measurement device and a measurement result of the third measurement device, and
• calculates a second correction value for correcting the second image data based on a measurement result of the second measurement device and the measurement result of the third measurement device,
• the substrate is transparent, and
• the second liquid includes white ink.
