Anti-offset powder
Regular price
$6.00
A fine powder is used during the platemaking process to prevent Newton's rings from forming between the positive transparency and the shiny surface of the plate. Many printers use talcum powder. Talcum works but is unsafe to breathe. The anti-offset powder is a micro-encapsulated (so it doesn't absorb water) food-grade corn starch product that does the same thing with less risk to your lungs. This fine powder is a commercial product normally sold in large quantities. You can buy a can of the stuff from us that will last 5 years and save the trouble of finding a place to store 44 pounds of corn starch.
