The paper stock is usually a continuous roll which is cut according to the size requirements of the customer. Different image widths are handled using different roll widths, and each width is usually done as a batch process of images all the same size. The light-sensitive photographic paper stock can be contained within light-tight packaging so that the minilab operator only needs to remove the old empty paper container and insert a full one, without needing to darken the room to prevent paper exposure.
