Disclosed are methods and systems for processing a web. The web (402) has a first surface, a second surface opposite the first surface, and includes a magnetic material. An example system includes a processing bed (202) configured to support the web while the first surface of the web undergoes one or more processing steps. The system also includes magnets (300) positioned relative to the processing bed so as to exert a magnetic force on the web that pulls the center of the web (403) toward the processing bed. The system further includes a conveyor belt (404) configured to move the web over the processing bed (202). The conveyor belt has a first contact surface and a second contact surface opposite the first contact surface. The first contact surface is configured to contact the second surface of the web, and the second contact surface is configured to contact the processing bed.
