Methods and apparatus are disclosed for improving the effectiveness with which a line scan camera may read information presented on the surface of an item, such as a flats mail item having name and/or address information printed thereon which is enclosed or partially covered in transparent and/or semi-transparent material. Some embodiments provide a camera platen having a surface area which promotes a smoothing and/or brushing of material covering the information on the surface of a mail item, thereby reducing wrinkles, angulations or deformities in the covering that might otherwise cause shadows and/or glare that could obscure the information. Smoothing and/or brushing may, for example, be achieved using a platen having surface areas formed of materials having different coefficients of friction.
