Treat it Right

For starters, the impact of treating dissipates over time, so material sitting in inventory for a number of weeks may not be at acceptable levels for quality printing when it is used. Add to this the variability that comes with different suppliers, some of which may be foreign companies, and Westerheim makes the case for bump treating at the printer's facility. Since bump treating is done to basically even out surface tension and re-establish previous levels, she points out that, many times, corona treaters used in these applications don't require lots of power.
