Inkjet dtf printer system and image forming method

An inkjet direct to film (DTF) printer system for producing a thermal transfer film original by forming an image by discharging ink onto a thermal transfer film and forming an adhesive layer on the image, comprising:

• a liquid discharger configured to discharge the ink onto the thermal transfer film;
• a dispenser unit which is a non-inkjet type, including a coating nozzle configured to discharge an adhesive liquid, and configured to apply the adhesive liquid on the image by discharging the adhesive liquid from the coating nozzle;
• a first carriage on which the liquid discharger is mounted, the first carriage being configured to move the liquid discharger in a main scanning direction;
• a second carriage on which the dispenser unit is mounted, the second carriage being configured to move the dispenser unit in the main scanning direction;
• a conveyor configured to convey the thermal transfer film in a sub-scanning direction intersecting the main scanning direction;
• and
• a processor configured to control operations of the liquid discharger, the dispenser unit, the first carriage, the second carriage, and the conveyor,
• wherein the processor is configured to form the adhesive layer by controlling the conveyor to perform a line feed after both the first carriage and the second carriage have finished a main scanning operation.
