摘要
Method for producing a pattern (15) by localized removal of a coating on a body (2) which is hollow and bounded by a wall (4), a first wall portion (7a) facing a second conjugate portion (7b), on a pair of etchable coated conjugate portions (14a, 14b), at least one layer of an etchable coating (12), the first conjugate portion (14a) including a non-etchable pattern (15), and the second conjugate portion (14b) being devoid, wherein there is available a laser beam (16) capable of impacting the etchable coating to remove it in the impact zone (21) and constitute the pattern without etchable coating (15), there is available pieces (22) of a solid material then able to form a barrier for the laser beam (16), is placed in the interior space (3) of the body (2) pieces of barrier material, the first conjugate portion (14a) is subjected to the impact of the er (16) and the pattern (15) is thus produced, and the interior (3) of the pieces (22) of the barrier material is emptied, so that the laser beam (16) is stopped by the barrier material , does not impact the second conjugate portion with etchable coating (14b) and thus does not remove an etchable coating in this second conjugate portion (14b).
