CLIAMS:1. A printing assembly (100) for printing an intricate pattern on a substrate, comprising:
a gravure printing unit (102) comprising,
an impression cylinder (202) to rotate about an impression axis, wherein the impression cylinder (202) is to support the substrate for printing;
an ink tray (204) to store a primary printing ink having a first colour; and
a printing cylinder (204) comprising a circumferential surface (304) to at least partially dip in the primary printing ink in the ink tray (204) and to substantially abut against a circumferential surface of the impression cylinder (202), the printing cylinder (204) comprising at least one engraving (306) on the circumferential surface (304) to carry the primary printing ink, wherein the at least one engraving (306) is provided in a block shape and is located on the printing cylinder (204) corresponding to location of the intricate pattern to be printed on the substrate, wherein the printing cylinder (204) is to rotate about a print axis (302) along with the impression cylinder (202) for the substrate to pass between the printing cylinder (204) and the impression cylinder (202), wherein the primary printing ink in the at least one engraving (306) is deposited on the substrate in the block shape for obtaining a primary print of the first colour on the substrate; and
an offset printing unit (104) downstream of the gravure printing unit (102) to receive the substrate having the primary print, the offset printing unit (104) comprising a printing instrument (400) for printing on the substrate with a secondary printing ink having a second colour, wherein the printing instrument (400) is to obtain non-printed spots in the intricate pattern over the primary print to create the intricate pattern in the first colour surrounded by the second colour on the substrate.

2. The printing assembly (100) as claimed in claim 1, wherein the at least one engraving (306) is in shape of one of a polygon, a circle, and an oval.

3. The printing assembly (100) as claimed in claim 1, wherein the intricate pattern is at least one of text, a picture, a logo, a geometrical design, an abstract design, and a trademark.

4. A method for printing an intricate pattern on a substrate, the method comprising:
printing, using a gravure printing unit (102), at least one block shape with a first colour on the substrate at a location where the intricate pattern is to be printed to obtain a primary print on the substrate;
passing the substrate with the primary print to an offset printing unit (104);
printing with a second colour over the primary print on the substrate, using the offset printing unit (104), wherein the printing with the second colour comprises providing non-printed spots in the intricate pattern on the primary print to create the intricate pattern in the first colour surrounded by the second colour on the substrate.
5. The method as claimed in claim 4, wherein the printing the at least one block shape comprises printing one of a polygon, a circle and an oval on the substrate.

6. The method as claimed in claim 4, wherein the printing with the second colour comprises providing the non-printed spots in shape of at least one of text, a picture, a logo, a geometrical design, an abstract design, and a trademark.

7. A gravure printing unit (102) comprising,
an impression cylinder (202) to rotate about an impression axis, wherein the impression cylinder (202) is to support a substrate for printing;
an ink tray (204) to store a primary printing ink having a first colour; and
a printing cylinder (204) comprising a circumferential surface (304) to at least partially dip in the primary printing ink in the ink tray (204) and to substantially abut against a circumferential surface of the impression cylinder (202), the printing cylinder (204) comprising at least one engraving (306) on the circumferential surface (304) to carry the primary printing ink, wherein the at least one engraving (306) is provided in a block shape and is located on the printing cylinder (204) corresponding to location of an intricate pattern to be printed on the substrate, wherein the printing cylinder (204) is to rotate about a print axis (302) along with the impression cylinder (202) for the substrate to pass between the printing cylinder (204) and the impression cylinder (202), wherein the primary printing ink in the at least one engraving (306) is deposited on the substrate in the block shape for obtaining a primary print of the first colour on the substrate;
wherein the gravure printing unit (102) is to couple upstream of an offset printing unit (104) for providing the substrate having the primary print to the offset printing unit (104) to print the intricate pattern on the substrate, and wherein the offset printing unit (104) is to print with a secondary ink of second colour over the primary print for creating non-printed spots in the intricate pattern over the primary print to obtain the intricate pattern in the first colour surrounded by the second colour on the substrate.

8. The gravure printing unit (102) as claimed in claim 7, wherein the at least one engraving (306) is in shape of one of a polygon, a circle, and an oval.
