Abstract
Method for removing a marking from a stratum surface involving the steps of superposing a pellucid film including a heat-softenable polymeric material over a marking so that the marking is in contact with the polymeric material and irradiating the marking and film with light energy to heat the marking and soften the polymeric material to thereby transfer the marking to the film.
