I use to work in a print shop, I created these collages by digging thru the trash LOl when no one was looking
. I'd lift things out of the trash perform test prints on the machines with said object then cut and paste these prints into collages then copy the collages again edit the settings. I also use to feed prints back in the machine and print on a paper multiple times so its a combination of all these processes. I would do these things in down times or break periods it was a way to make work less boring! and also for me to use the machines to make art which was really fun to have access to!
