I was interested in your question, so I pulled up a blog from 2019 that talked about manufacturers moving from screen printing to digital printing of quilting cottons:

The blog states that Michael Miller, QT Fabrics and Hoffman California are all doing a majority or all of their fabric by digital printing.
“For Hoffman, the cleaner printing process is also a priority. “Textile manufacturing is not good for our planet, and the digital printing process is by far the most eco-friendly form of textile printing that has come about,” Chisholm says. “We believe it is the right way to print and where textile manufacturing will go as a whole.” This cleaner process also means that digital printing can be done in the US, not just Korea and Japan where screen printing is currently done.
Apparently, digital printing cannot produce metallics or other textures, so if you see those effects, it was likely screen printed.
