Marking process of an object (P) comprising the steps of: a) providing processing means having a word processing software and a display and operationally connected to a laser apparatus for the marking of an object (P) having a marking head and at least one deflection mirror moved depending on the desired alignment between the object (P) and the data (D) to be marked, b) entering one data (D) by means of the word processing software suitable for being engraved on an object (P), c) switching on detecting means which are positioned above a work top (L) of the apparatus to receive the object (P) to be marked, d) positioning the object (P) to be marked above the work top (L), e) acquiring an image of the object (P) to be marked and sending it to the word processing software to show it on the display , f) checking via the display whether the data (D) entered is at least partly superimposed on the image of the object (P), g) starting the marking of the object (P), characterised by comprising the further step of: moving said data (D) via said word processing software depending on a predefined desired alignment between the object (P) and the data (D) to be marked, moving said at least one deflection mirror and/or said marking head depending on the desired alignment between the object (P) and the data (D) to be marked, and wherein said checking step f) comprises the step of directly controlling on the display whether the data (D) is at least partly superimposed on the two-dimensional image of the object (P) to be marked. a) providing processing means having a word processing software and a display and operationally connected to a laser apparatus for the marking of an object (P) having a marking head and at least one deflection mirror moved depending on the desired alignment between the object (P) and the data (D) to be marked, b) entering one data (D) by means of the word processing software suitable for being engraved on an object (P), c) switching on detecting means which are positioned above a work top (L) of the apparatus to receive the object (P) to be marked, d) positioning the object (P) to be marked above the work top (L), e) acquiring an image of the object (P) to be marked and sending it to the word processing software to show it on the display , f) checking via the display whether the data (D) entered is at least partly superimposed on the image of the object (P), g) starting the marking of the object (P), characterised by comprising the further step of: moving said data (D) via said word processing software depending on a predefined desired alignment between the object (P) and the data (D) to be marked, moving said at least one deflection mirror and/or said marking head depending on the desired alignment between the object (P) and the data (D) to be marked, and wherein said checking step f) comprises the step of directly controlling on the display whether the data (D) is at least partly superimposed on the two-dimensional image of the object (P) to be marked. moving said data (D) via said word processing software depending on a predefined desired alignment between the object (P) and the data (D) to be marked, moving said at least one deflection mirror and/or said marking head depending on the desired alignment between the object (P) and the data (D) to be marked, and wherein said checking step f) comprises the step of directly controlling on the display whether the data (D) is at least partly superimposed on the two-dimensional image of the object (P) to be marked. <EOS>
