OMR CARD OR OMR SHEET FOR PREVENTING UNFAIR CONDUCT FROM GENERATING AND A PRINTING METHOD OF ANSWER MARKING PORTIONS THEREOF

摘要

PURPOSE: An OMR card or sheet for an unfair practice and a method for printing marked parts of an answer sheet are provided to overlay-print a special ink on the marked parts of an answer sheet. CONSTITUTION: An OMR card for an unfair practice comprises a timing track(12) for OMR recognition and a plurality of marked parts(14). The marked parts have upper/lower portions of a rounded rectangular shape. The area of inner rim(16) of the marked parts is screen-printed by the OCR ink or UV OCR ink in which blue, red and yellow colors are mixed. So that a PCS numerical value can be smaller than 0.20, the printing is performed.
