Business forms, particularly financial instruments such as checks, money orders, bank drafts, etc., are constructed with CF and CB, or self-imaging, sheets. MICR characters may be printed on the sheets without subsequent smearing by applying a W curable ink to a CF or self-imaging sheet so as to block the CF or self-imaging material at the selected portion to which the ink is applied, thereby rendering it incapable of functioning as a CF or self-imaging element. The ink is applied to a moving web in a continuous manner prior to printing to form a continuous strip of ink, which moves past a W radiation source so that it is quickly cured and does not adversely affect high speed production. The ink may also be applied to a CB, CF, or self-imaging sheet as a security feature, selectively blocking the transmission of confidential indicia at the selected portion of the sheet with which it is associated.
