STPI is a famous printing studio/gallery/awesome place. This image wasn't in the main exhibition but I found it off to the side and was quite taken with it. For the techies out there it had shaped intaglio/etching plates, possibly printed twice, once with a colour roll and others with just etching or others with etching and aquatint. So there was a particular emboss on some image while others were on this massive bleedprint plate that were inked in different colours.
If you are ever in Singapore and printing inclined you should take a looksee, but be warned they sometimes close for days when taking down and putting up shows.
