A method of correcting post- warp in a multi-layer product under prevailing conditions includes detecting an initial warp value of the multi-layer product indicative of an initial degree of warpage therein. A moisture-conditioning setpoint is selected from among a plurality of moisture-conditioning setpoints that have been correlated to respective initial warp values and their associated post-warp values for prior-made multi-layer products, based on a comparison between the detected initial warp value and the respective initial warp values in the database. Further, the method includes adjusting a moisture content in at least one layer of the multi-layer product according to the selected moisture-conditioning setpoint.
