The Epson F170 has been ideal for getting started with sublimation. It's easy to use, prints vibrant and defined colors, and has allowed me to personalize various projects with excellent results. As a beginner, it has given me a lot of confidence to learn and create without complications. I definitely recommend it for anyone starting out in sublimation.

No returns and no support. If it doesn't work properly, too bad.
Style: Printer & Inks, Style: Printer & Inks
I was fairly happy with my Epson ET 2800, but was told that I'd get better colors with the F170. So I bit the bullet. The installation went smoothly and I was printing in short order. It was when I started printing items that had some dark gray that I noticed the problem. It was printing green. I contacted Epson tech support and they answered the phone almost immediately. (And how rare is that??) The woman I spoke with seemed to be familiar with the problem and advised me to modify the printer preferences and change the color correction from "ICM" to "No color correction". Well, it wasn't printing green anymore. Now the grays were brown. At this point, she ran out of ideas and gave me an email address for the second level of tech support and asked if I'd send a photo of the printed fabrics showing the problem. I did. That was over three weeks ago. I've sent a couple of followup emails, but they're ignoring me. But the best news was discovering that there are no returns on this product. I didn't think that was a thing with Amazon and I've never had any problems before. So now the 30-day return window is about to elapse and it appears that I'm stuck with an oversized doorstop. In the photo I'm including with this review, the fabric on the upper-left was printed with my Epson ET 2800. On the upper right, the F170 with ICM color correction. On the bottom, the F170 with no color correction.

Epson SureColor F170 Sublimation Printer Rocks!
Style: Printer & Inks, Style: Printer & Inks
TI’m a newbie at sublimation, and this is my first sublimation printer. I love it! I can’t wait to make more things! I like that it’s not too large, but still can print up to 8.5x14”. The quality seems to be really good, but I also don’t have any other printer to compare it to. This was my very first project! I’m very happy with it so far!
