Device for printing by means of serigraphy an object which has at least a conical portion, the conical portion having a centre of conicity and an angle of conicity, the device comprising:

• a frame;
• a screen which can be moved relative to the frame, the screen carrying a mesh which has a pattern to be printed on the conical portion of the object, the pattern having the shape of a conical evolute which has a pattern centre and an angular extent range of the pattern;
• a doctor blade which is carried by the frame, the doctor blade being capable of pressing the mesh of the screen against the conical portion of the object in order to apply the pattern to the conical portion of the object, wherein the device comprises:
• means for rotatably driving the screen about a rotation axis, the means for rotatably driving the screen comprising a single motor,
• first means for moving the motor for rotatably driving the screen, the first movement means extending in a first direction,
• second means for moving the motor for rotatably driving the screen, the second movement means extending in a second direction perpendicular relative to the first direction, the first movement means carrying the second movement means.
