Method of mounting a flexographic printing plate with structured patterned backing tape
View Patent ↗A method of mounting a flexographic printing plate with structured patterned backing tape includes attaching a first end of a structured patterned backing tape to a printing plate cylinder at a scribe line. The structured patterned backing tape is wrapped around the printing plate cylinder. A second end of the structured patterned backing tape is cut at the scribe line. A first end of a flexographic printing plate is attached to the printing plate cylinder at an offset seam location ahead of the scribe line. The flexographic printing plate is wrapped around the printing plate cylinder. A second end of the flexographic printing plate is cut at the offset seam location.
1. A method of mounting a flexographic printing plate with structured patterned backing tape comprising:
attaching a first end of the structured patterned backing tape to a printing plate cylinder at a scribe line of the printing plate cylinder;
wrapping the structured patterned backing tape around the printing plate cylinder;
cutting a second end of the structured patterned backing tape at the scribe line;
attaching a first end of the flexographic printing plate to the printing plate cylinder at an offset seam location relative to the scribe line;
wrapping the flexographic printing plate around the printing plate cylinder; and
cutting a second end of the flexographic printing plate at the offset seam location,
wherein the offset seam location is approximately 4.5 inches offset relative to the scribe line.
2. The method of claim 1 , further comprising:
cleaning a mounting surface of the printing plate cylinder.
3. The method of claim 1 , wherein the structured patterned backing tape comprises ChannalBAC™.
4. The method of claim 1 , wherein the structured patterned backing tape comprises an adhesive layer.
5. The method of claim 1 , wherein wrapping the structured patterned backing tape comprises overlapping the second end of the structured patterned backing tape over the first end of the structured patterned backing tape at the scribe line.
6. The method of claim 1 , wherein the second end of the structured patterned backing tape meets the first end of the structured patterned backing tape at the scribe line without gap after cutting.
7. The method of claim 1 , wherein wrapping the flexographic printing plate comprises overlapping the second end of the flexographic printing plate over the first end of the flexographic printing plate at the offset seam location.
8. The method of claim 1 , wherein the second end of the flexographic printing plate meets the first end of the flexographic printing plate at the offset seam location without gap after cutting.
9. The method of claim 1 , wherein the flexographic printing plate comprises embossing patterns of micron-fine lines or features.
10. The method of claim 9 , wherein the embossing patterns comprise lines or features having a width in a range between approximate 1 micron and 9 microns.
