Transitioning to a Processless Plate

 

The use of processless plates has been gaining traction for some time now.  There are several advantages to using these plates.  The most advantageous is the elimination of the chemistry used to develop and remove the non-image area of the plate.  These chemistries typically have high alkalinity and can be difficult to handle as well as dispose of.  By eliminating this step you remove any potential problems with the processor, associated chemistries and plate waste as the processor is completely eliminated.

By making the change to these plates you have eliminated issues in the prepress area but may create others in the pressroom.  Keep in mind that the plates still have to be developed and this is typically done on the press.  We have to consider the fountain solution chemistry, which comes in direct contact with the plate.  Because this plate is “different” with respect to the coating and the way it is processed, the use of a mild acid fountain solution is recommended.  The mild acid solution will better clean the plate’s non-image area and keep it free of tinting and toning.

RBP offers an array of mild acid fountain solutions that have proven to work on the processless plate.  Contact your RBP sales representative or Customer Support at cs@rbpchemical.net for your free sample.
