Method of manufacturing a press plate, a press plate, a method of embossing a floor panel, and a floor panel
View Patent ↗A method of manufacturing a press plate for applying a surface structure onto a floor panel, wherein the press plate includes a press plate surface, comprises the following steps: first fine projections are created on the press plate surface, then the resulting fine projections are covered by a surface treatment resistant material, and subsequently the press plate surface including the resistant material is submitted to a surface treatment.
1. A method of manufacturing a press plate for applying a surface structure onto a floor panel, wherein the press plate includes a press plate surface, the method comprising:
creating fine projections on the press plate surface,
subsequently providing a chrome layer on the press plate surface to create the same gloss level on the press plate surface on the areas having the fine projections and the areas adjacent the fine projections,
covering the fine projections with a surface treatment resistant material, and
submitting the press plate surface including the surface treatment resistant material to a surface treatment such that press plate surface structure at the fine projections is different from that in adjacent portions.
2. The method according to claim 1 , wherein the surface treatment is a chemical surface treatment.
3. The method according to claim 2 , wherein the chemical surface treatment is an etching treatment.
4. The method according to claim 1 , wherein creating the fine projections on the press plate surface comprises etching the press plate surface adjacent to intended locations of the fine projections.
5. The method according to claim 1 and further comprising removing the surface treatment resistant material from the press plate surface after the surface treatment.
6. The method according to claim 1 , wherein covering the fine projections with the surface treatment resistant material comprises printing the surface treatment resistant material onto the fine projections.
7. The method according to claim 1 , wherein after submitting the press plate surface including the surface treatment resistant material to the surface treatment, the press plate surface structure at the fine projections is such that the gloss level is higher than in adjacent portions.
8. The method according to claim 1 , wherein the fine projections on the press plate surface are elongated projections having a width of less than 1 millimeter.
9. The method according to claim 1 , wherein the surface treatment is a sand blasting treatment.
10. A method of manufacturing a press plate for applying a surface structure onto a floor panel, wherein the press plate includes a press plate surface having fine projections projecting away from adjacent surface portions, the method comprising:
providing a chrome layer on the press plate surface on the areas having the fine projections and the adjacent surface portions before the fine projections are covered by a surface treatment resistant material to create the same gloss level on the press plate surface on the areas having the fine projections and the adjacent surface portions,
subsequently covering the same gloss level on the fine projections with surface treatment resistant material, and
submitting the press plate surface including the surface treatment resistant material to a surface treatment such that at least some the surface treatment resistant material remains and the press plate surface structure adjacent the fine projections is different from that under the surface treatment resistant material.
11. The method according to claim 10 , wherein the surface treatment is a chemical surface treatment.
12. The method according to claim 11 , wherein the chemical surface treatment is an etching treatment.
13. The method according to claim 10 and further comprising removing the surface treatment resistant material from the press plate surface after the surface treatment.
14. The method according to claim 10 , wherein covering the fine projections with the surface treatment resistant material comprises printing the surface treatment resistant material.
15. The method according to claim 10 , wherein after submitting the press plate surface including the surface treatment resistant material to the surface treatment, the press plate surface structure at the fine projections is such that the gloss level is higher than in adjacent portions.
16. The method according to claim 10 , wherein the fine projections on the press plate surface are elongated projections having a width of less than 1 millimeter.
17. The method according to claim 10 , wherein the surface treatment is a sand blasting treatment.
18. The method according to claim 10 wherein the surface treatment is a chrome surface treatment.
