Business entities use various types of checks for their daily financial transactions. These checks can include but are not limited to personal checks, manual business checks, computer checks, and blank business checks or blank personal checks. These above-mentioned checks can be further divided into several subcategories. The different formats of checks are checks on top, checks in the middle, checks on the bottom, three to a page checks, laser checks, and z fold pressure sealed checks. A pressure check can be defined as a check that contains a full-page self-mailing document that has a seal on it. This seal is specially made. When this seal is in use, the document is sealed with a unique bonding procedure. This sealing process does not require any water or heat for its completion. When the document is folded, you can notice a few patterns that perfectly align themselves on the edge of the document. These patterns are specially formulated by the use of a specific type of cohesive glue.
