Pros and Cons of Pre-, Post- and No-bake Plates

Two problems with post-baking that printers need to be aware of stem from a lack of understanding how to undertake the post-bake process. If the oven is too hot, it can weaken the aluminum, Zaloom explains. "Some recommended temperatures for post-baking are close to the annealing temperature of aluminum—the temperature at which aluminum begins to change its physical characteristics." A too-hot oven can warp the plate, leading to problems when the plate is mounted and the plate usually cracks.
