InkSonic R1390 A3 DTF Printer Review: Affordable Printing on Dark Fabrics

If you’ve ever dreamed of starting your own clothing personalization business or expanding your current one, one of the biggest challenges has been printing vibrant designs on dark fabrics. Traditional printing methods often fail to give sharp, vivid results on dark garments, and many solutions are expensive or complicated to set up.

That’s where the InkSonic R1390 A3 DTF Printer comes in — an affordable, high-quality direct-to-film (DTF) printer that makes vibrant printing on dark and light fabrics easier than ever.

Why the InkSonic R1390 A3 DTF Printer Stands Out

The InkSonic R1390 A3 DTF Printer delivers exceptional printing quality at an affordable price. At just $2499, it offers features that are usually found in far more expensive machines, making it an ideal choice for small business owners, entrepreneurs, and hobbyists looking to produce professional-quality work without breaking the bank.

What impressed me most during my review (which you can watch in full detail in my video here) was how easy it was to assemble and set up. The package comes with everything you need, including:

  • A manual heat press
  • A roll of DTF film
  • Ink bottles (two yellow, two magenta, two cyan, two black, four white)
  • Nozzle cleaning liquid and nozzle protection liquid
  • Two bags of DTF powder
  • USB stick with all software and tutorials
  • Instruction manual with detailed illustrations

Everything arrives neatly packaged in a wooden crate, fully protected, making the unboxing a safe and exciting experience.

Easy Assembly and Setup

The first step is assembling the roll holder for the DTF film and attaching the front tray with the built-in cutter. The InkSonic R1390 A3 DTF Printer includes clear instructions and tutorial videos to guide you through the process.

Connecting the printer to your computer is straightforward:

  1. Plug in the USB and dongle using the provided adapter.
  2. Connect the printer via USB cable.
  3. Turn the printer on from the back switch and the front button.
  4. Feed the DTF film and cut excess with the cutter.

Next, install the drivers and software from the USB stick. Inside, you’ll find all the folders and tutorial videos needed to walk you through every step — from assembly to printing your first designs.

Ink Filling and Cartridge Preparation

Once setup is complete, you fill the ink tanks in order — everything is clearly labeled for ease of use. The printer includes enough ink for multiple prints, with white ink available in abundance for perfect base layers.

Testing the Printer

The real magic happens when printing your first design. The InkSonic R1390 A3 DTF Printer prints vibrant, sharp, full-color designs with a strong white base layer on both dark and light garments. Even complex, colorful designs come out beautifully — no ghosting, no fading, no extra effort.

Applying DTF Powder and Pressing

After printing, apply DTF powder generously to cover the design completely. The powder included in the package is enough for many prints, and it’s reusable.

Then preheat the garment, align the print, place a Teflon sheet on top, and press. The included manual heat press works beautifully for this step, pressing at 320°F for about 20 seconds (longer for larger designs).
