===Designing and printing=== There are specific dimensions of designing OMR sheets with 0.05 mm precision on scale. If the dimensions are not up to the precision scale, the accuracy of the OMR sheet may vary, so the sheet should be designed, printed and cut perfectly. * Single Part β Sheets are printed on 105 gsm to 120 gsm paper on A4/Legal sheets. * Double Part (Carbonless) β Two sheets are printed; one on 105 gsm paper and one on 60-70 gsm paper on A4 sheets. The bottom of the first sheet and the top of the second sheet are chemically treated so that the impression of the first sheet comes on the second sheet. * Three Part (Carbonless) β Three sheets are printed on one 105 gsm paper and the other two are printed on 60-70 gsm paper on A4 sheets. The bottom of the first sheet, the top and bottom of the second sheet, and the top of the third sheet are chemically treated so that the impression of the first sheet comes on the second and third sheets.
