When you say smears what are you meaning?
Do you mean the places where it looks dull either do to where the chocolate comes off the acetate or where the temper was not right? Or do you mean there are finger prints and smudes acutly on the acetate before pouring the chocolate onto it.
How are you tempering your chocoalte? Marble slab?
Whats your technique? Scraper, and off set?
How are you testing your temp? Lip test ot therm?
Just some questions to ask for a more helpfull answer...
