The multiple plate print I was creating today went wrong as it was going through the press. The sandpaper aquatint crab plate that I had inked up earlier and left on the hot plate was stuck to the paper when peeling it back off the press.
The class tutor said it was likely to be because of the water soluble inks used. I tried the single plate again and it worked well.
I am going to cut this print out and put it onto mount board and place that onto the multiple orange print above so it will stand out from the paper and correct the accident. Printmaking is all about trial and improvement after all!
