Method of printing uniform line widths with angle effect
View Patent ↗A method of printing uniform line widths with angle effect includes transferring ink to a flexo master comprising printing patterns disposed at an adjusted angle relative to a directional printing axis and transferring ink from the flexo master to a substrate. A flexographic printing system includes an ink roll, an anilox roll, a plate cylinder, a flexo master, and an impression cylinder. The flexo master is disposed on a plate cylinder. The flexo master includes printing patterns disposed at an adjusted angle relative to a directional printing axis.
1. A method of printing uniform line widths with angle effect comprising:
transferring ink from an anilox roll to a flexo master comprising printing patterns disposed at an adjusted angle relative to a directional printing axis, wherein the adjusted angle is in a range between approximately 15 degrees and approximately 30 degrees; and
transferring ink from the printing patterns to a transparent substrate,
wherein the printing patterns comprise fine lines with a line width less than 10 microns, and
wherein the ink comprises ink suitable for plating by electroless plating.
2. The method of claim 1 , further comprising:
transferring ink from an ink pan to an ink roll;
transferring ink from the ink roll to the anilox roll; and
removing excess ink from the anilox roll.
3. The method of claim 1 , wherein the adjusted angle is approximately 15 degrees.
4. The method of claim 1 , wherein the adjusted angle is approximately −15 degrees.
5. The method of claim 1 , wherein the adjusted angle is approximately 25 degrees.
6. The method of claim 1 , wherein the adjusted angle is approximately −25 degrees.
7. The method of claim 1 , wherein the adjusted angle is in a range between approximately −15 degrees and approximately −30 degrees.
8. The method of claim 1 , wherein the directional printing axis is a machine printing axis.
9. The method of claim 1 , wherein the directional printing axis is a transverse printing axis.
10. The method of claim 1 , wherein the printing patterns comprise lines with a line spacing less than approximately 10 microns.
11. The method of claim 1 , wherein the printing patterns comprise lines with a width in a range between approximately 10 microns and approximately 50 microns.
12. The method of claim 1 , wherein the printing patterns comprise lines with a line spacing in a range between approximately 10 microns and approximately 50 microns.

an ink roll;
an anilox roll;
a plate cylinder;
a flexo master disposed on the plate cylinder, wherein the flexo master comprises printing patterns disposed at an adjusted angle relative to a directional printing axis, wherein the adjusted angle is in a range between approximately 15 degrees and approximately 30 degrees; and
an impression cylinder,
wherein the printing patterns comprise fine lines with a line width less than 10 microns, and wherein the ink comprises ink suitable for plating by electroless plating.
14. The flexographic printing system of claim 13 , further comprising:
an ink pan; and
a doctor blade.
15. The flexographic printing system of claim 13 , wherein the adjusted angle is approximately 15 degrees.
16. The flexographic printing system of claim 13 , wherein the adjusted angle is approximately −15 degrees.
