The R1390 C13A is an A3+ (13-inch) direct-to-film printer built on the Epson L1800 printhead, aimed at small shops printing transfers for shirts, flags, bags and hats. It prints at up to 2880x1440 DPI with a 3-in-1 white ink system, one-click ink filling and white ink circulation, and adds a built-in cutting blade and a three-level air suction control for steady film feed. InkSonic's own RIP software handles layout, cropping, air holes, feathering and task traceback. Buyers call the output bright and vibrant and the machine reliable once dialed in, but several describe setup as a real challenge and one reported a major ink leak on the first unit.

Buyers rate it highly and describe bright, clean, vibrant prints and a machine that runs reliably once configured. The main complaints are a difficult setup process and an ink leak on one first unit.
The R1390 A3+ DTF Printer C13A prints heat transfers on film. It has an A3+ 13-inch print width and uses an L1800 printhead. It is suited to shirts, flags, canvas bags and hats.
Ink setup takes one click: the printer fills the ink and circulates the white ink automatically, and setup takes 60 seconds. A built-in cutting blade trims transfers, and a maintenance door on each side gives easy access. An adjustable 3-level air suction control keeps the film steady while loading.
The included InkSonic RIP software is self-developed.
