Rubika® supports the placement of opaque rectangular regions on a page. Commonly, Rubika uses a white rectangle to conceal barcodes or OMR that might not be suitable for a particular inserter. Rubika can then apply new barcodes, OMR, and sequence numbers on top of the opaqued region.

Masking can be applied to visually hide confidential or sensitive information such as Social Security Numbers and PIN or account numbers. Rubika can then apply i.e. XXX-XX-XXXX on top of the opaqued region.
