Set-Off - What is set off?
Definition of SET OFF:
In printing, set-off is a defect in the print characterised by the transfer of wet ink from the substrate to another surface. Set-off is commonly seen in the printing of sheets, where printed sheets are usually stacked on top of one another; if the ink on a sheet doesn't dry properly before the next sheet exits the printer, the ink will transfer to the back of the next sheet. Set-off can occur if an ink doesn't dry quickly enough, if the substrate isn't absorbant enough (leaving a thick film of wet ink on the top of the substrate), or if the paper is cold (which slows the drying process).
Set-off is also the basic principle behind offset printing methods; in offset printing, ink is transferred from an image carrier or imaging device to the substrate and this process relies on the ink not drying in place on the transfer medium.
