Also 1541 Grafton was committed to Fleet Prison for printing a "sedicious epistle of Melanctons" and was also accused by the Privy Council of printing ballads defending the late Thomas Cromwell. In April 1543, he and seven other printers, among them Whitchurch, were sent to prison "for printing such books as were thought to be unlawful." In Grafton's case it was for having printed the Great Bible. He spent six weeks in prison and was bound in £300 neither to sell nor to print any more Bibles until the King and clergy should agree upon a translation.
