An apparatus and method for reading a coded pattern, symbol or indict such as a barcode. The apparatus and method improves captured resolution with a marker or fiducial input closed loop system. In the present invention, a pre-scan of the pattern, such as a barcode, is performed and fiducials of the barcode are identified. Calculations from these fiducial locations are used to determine the minimum field of view that will substantially capture the fiducials. In an embodiment of the invention, a variable magnification system of the apparatus can be actuated to this minimum field of view and a full resolution final image of the pattern is then captured.

Apparatus as claimed in claim 6, characterized in that the bore of the drawing dies (8, 9, 10, 11, 15) extends conically in a decreasing tapered shape. 14. Apparatus as claimed in claim 6, characterized in that the shaping device (3) comprises a first group of a plurality of tightly spaced drawing dies (8, 9, 10, 11) arranged one behind the other, and an additional drawing die (15) is arranged behind them and spaced apart therefrom in production direction. 15. Apparatus as claimed in claim 14, characterized in that an entry opening of each successive drawing die of the first group has an entry opening with a diameter greater than an exit opening of the drawing die before it.
