The registrars shall direct the preparation, adjustment and programming of the voting tabulator by a suitable technician who is adequately trained by a representative of the manufacturer and approved by the Secretary of the State in accordance with the ballot layout established by the municipal clerk. The municipal clerk and registrars shall direct a printer approved by a representative of the manufacturer or the Secretary of the State to print a number of official ballots determined by the registrar of voters and a number of absentee ballots determined by the municipal clerk in accordance with specifications approved by the Secretary of the State. Official and absentee ballots may be printed on different colored paper to enable poll workers to readily identify the different types of ballots. The ovals on the official ballots may be printed in a color other than black to ensure greater accessibility for individuals with disabilities. Finally, ballots may be printed on both sides of the page as long as a separate page of instructions is provided with each absentee ballot and is available for use in each polling place.
