Enhanced method for product marking
A layline labeling process includes providing a layline material including a carrier film and a plurality of ink regions applied to the carrier film; applying a laser to laser-treat the ink side of the layline material to remove a first portion of ink to form a pattern of labeling; applying the laser treated layline material to a product with the ink side against the product; curing the product; and removing the carrier film after curing, wherein a second portion of ink of the ink regions of the laser treated layline material not removed by the laser treatment remains bonded to an outer layer of the product. Because of the laser treatment to form the pattern of labeling where the ink has been removed from the carrier film, the labeling is visible by the contrast of the outer layer of the product where the ink was burned away, against the remaining ink that has bonded to such outer product layer during curing.
1. A method of labeling a product comprising the steps of:
providing a layline material including a carrier film and a plurality of ink regions applied to an ink side of the carrier film;
applying a laser to laser-treat the ink side of the carrier film material to remove a first portion of ink from the ink regions of the carrier film to form a pattern of labeling;
applying the laser treated layline material to a product with the ink side against the product;
curing the product; and
removing the carrier film after curing, wherein a second portion of the ink regions of the laser treated layline material not removed by the laser treatment remains bonded to an outer layer of the product to provide contrast with the pattern of labeling.
2. The method of labeling a product of claim 1 , wherein the ink regions each comprises a first ink layer and a second ink layer, and the laser removes the first portion of ink from first and second ink layers to form the patterning of labeling.
3. The method of labeling a product of claim 2 , wherein the first and second ink layers are different colors.
4. The method of labeling a product of claim 1 , further comprising:
passing the layline material by an encoder;
reading a position of the layline material with the encoder; and
based on the read position, the encoder generating an output signal to a laser device to control a timing of the laser treatment to control the forming of the pattern of labeling.
5. The method of labeling a product of claim 4 , wherein the layline material includes a non-ink film side opposite from the ink side, and the layline material passes by the encoder with the non-ink film side facing the encoder.
6. The method of labeling a product of claim 1 , wherein the laser treatment burns off the first portion of ink from the ink regions on the ink side of the carrier film.
7. The method of labeling a product of claim 1 , further comprising cutting the laser treated layline material such that layline material including at least one ink region is applied to the product.
8. The method of labeling a product of claim 1 , further comprising providing the layline material from a spooled source of layline material, and feeding the layline material from the spooled source to a laser marking device that applies the laser to perform the laser treatment.
9. The method of labeling a product of claim 1 , wherein the carrier film is a polyethylene or polypropylene film.
10. The method of labeling a product of claim 1 , wherein the carrier film is Mylar.
11. The method of labeling a product of claim 1 , wherein the product is a hose product and the laser treated layline film is applied to an outer surface of the hose product.
12. A layline laser labeling system comprising:
a laser marking device; and
a feeding mechanism for feeding a layline material to the laser device;
wherein the layline material includes a carrier film and a plurality of ink regions applied to an ink side of the carrier film, and the laser marking device laser-treats the ink side of the layline material to remove a first portion of ink from the ink regions of the carrier film to form a pattern of labeling; and
further comprising a product application system that applies the laser treated layline material to a product and removes the carrier film, wherein another portion of the ink regions of the laser treated layline material not removed by the laser treatment remains bonded to the carrier film.
13. The layline labeling system of claim 12 , wherein the feeding mechanism includes a spool for providing the layline material and rollers for feeding spooled layline material to the laser marking device.
14. The layline labeling system of claim 12 , further comprising an encoder, wherein:
the feeding system passes the layline material by the encoder;
the encoder reads a position of the layline material; and
based on the read position the encoder generates an output signal to the laser marking device to control a timing of the laser treatment to control the forming of the pattern of labeling.
