  • Gum Etch is a blend of pure gums with extra desensitizers and 
    film formers. 

    In plate processors: assures plates are properly desensitized 
    and stored for short & long term. When water hits the plate it 
    reactivates desensitizing agents, assures quick clean start-ups.
    On plate by hand: use to store a plate before printing or when 
    the time comes save the plate for later use.
    On metering rollers: to keep desensitized, water attractive and 
    free of ink.
    As a fountain solution additive: to eliminate scumming, open 
    tiny reserves, eliminate slight scratching on plates caused by dirty 
    paper stock and help control water speeds.

    Recommendations for use:

    Plate processors: Use Gum Etch straight out of the container.
    On plates by hand: Pour a liberal amount onto a clean shop 
    towel and wipe with a side-to-side motion over the entire plate. 
    On metering rollers: Clean ink off the metering roller, pour 
    Gum Etch onto a clean sponge or shop towel, wipe metering 
    roller with a side-to-side motion until entire roller has been treated.
    A fountain solution additive: Add to fountain solution in 
    increments of 1% per mixed volume of water. Lowers pH, eliminates 

    scumming and keep reverses open.
