Greetings,
From an ex-woodworker and now radio restorer.
The acrylic transfer method is a way to print an image on paper, glue it face down and then wash away the paper leaving the image trapped [transferred] on the glue.
Knowing about this could be important if you ever have to restore old furniture that has photofinish on it. Photofinish is a photo image of grain that was used quite a bit on radios of the 1930s and on other furniture.
Pictures are on the binary page.
