         5 . A deep-drawn tray having a rolled edge and an encircling sealing face, where the deep drawn tray is capable of being sealed to a plate via the encircling sealing face, further comprising a lacquer provided on the rolled edge. 
     
     
         6 . The deep-drawn tray of  claim 5 , where the deep-drawn tray is an aluminum tray 
     
     
         7 . The deep-drawn tray of  claim 5 , wherein the lacquer is also provided on at least one of the encircling sealing face and the opposite surface of the deep-drawn tray. 
     
     
         8 . The deep-drawn tray of  claim 5 , wherein one or more of the color, brightness, and intensity of the lacquer along the rolled edge changes. 
     
     
         9 . A method for producing a tray made of a continuous material, the tray having a rolled edge and an encircling sealing face and being capable of being sealed to a plate via the encircling sealing face, and further comprising a colored lacquer overprint provided on the rolled edge, the method comprising:
 a. applying a marking to the continuous material;   b. punching out a tray material from the continuous material based upon a position of the applied marking; and   c. deep-drawing the tray material to form the desired tray based upon the position of the applied marking;   wherein the method further comprises applying the colored lacquer overprint to the continuous material in an area that will be an inside and/or outside of the rolled edge, or applying the colored lacquer overprint to the tray material in an area that is an inside and/or outside of the rolled edge.   
     
     
         10 . The method of  claim 9 , further comprising printing the continuous material prior to punching out the tray material. 
     
     
         11 . The method of  claim 9 , wherein applying the marker to the continuous material occurs before or optionally during printing the continuous material.
