    DRAWINGS

    [0106] The drawings described herein are for illustrative purposes only of selected embodiments and not all possible implementations, and are not intended to limit the scope of the present disclosure.

    [0107] The disclosure is further explained below with reference to the figures. The figures show possible embodiments of the disclosure. In principle, however, combinations or variations of the embodiments are also possible within the scope of the disclosure.

    [0108] FIGS. 1A, 1B, 1C and 1D schematically show a detail of the cross-section of a raw panel after various process steps according to one embodiment of the method; and

    [0109] Corresponding reference numerals indicate corresponding parts throughout the several views of the drawings.

    DETAILED DESCRIPTION

    [0110] Example embodiments will now be described more fully with reference to the accompanying drawings.

    [0111] FIG. 2 schematically shows a cross-section of two interlocked panels with complementary retaining profiles according to one embodiment of the raw panel.

    [0112] FIG. 1A schematically shows a detail of the cross-section of a raw panel 10 which is provided for implementing the method according to one embodiment. The raw panel 10 has a panel upper face 11 and a panel lower face 12 (not shown) and a pair of opposing panel edges 13 (one not shown). The raw panel 10 comprises a carrier plate core 14 and a print substrate layer 15 applied onto the panel upper face 11. The print substrate layer 15 in the embodiment shown in FIG. 1A comprises three layers obtained by applying a first melamine resin layer 16 onto the carrier plate, applying a paper layer 17 onto the first melamine resin layer 16, and applying a second melamine resin layer 18 onto the paper layer 17.

    [0113] FIG. 1B schematically shows the detail of the cross-section of the raw panel 10 of FIG. 1A, wherein a chamfer 19 has been formed between a panel edge 13 of the pair of opposing panel edges and the panel upper face 11. The chamfer 19 was for example obtained by milling the corner between the panel edge 13 and the panel upper face 11.

    [0114] FIG. 1C schematically shows the detail of the cross-section of the raw panel 10 from FIG. 1B, wherein the panel edge 13 has been sealed. An impregnating agent 20 was applied onto the panel edge 13 and the chamfer 19. The impregnating agent 20 was a solution of 7 wt.-% 2-methoxy-methylethoxy-propanol in C11-C13 isoalkanes, which was sprayed onto the chamfer 19 and the panel edge 13. Here, the impregnating agent is absorbed into the raw panel 10 at the points where it was applied.

    [0115] FIG. 1D schematically shows the detail of the cross-section of the raw panel 10 of FIG. 1C, wherein the panel edge 13 was additionally sealed by coating the chamfer 19 with a sealing lacquer 23. The sealing lacquer was a polyurethane-modified acrylate-based lacquer which was at least partially cured at a wavelength in a range of 10 nm to 450 nm.

    [0116] As a result, a raw panel 10 with sealed panel edges 13 was obtained.

    [0117] FIG. 2 schematically shows the cross-section of two interlocked panels 10 comprising complementary retaining profiles 21 according to one embodiment of the raw panel 10. The dashed box exemplarily shows the detail shown in FIGS. 1A to 1D. The panels 10 have a panel upper face 11 and a panel lower face 12 and a pair of opposing panel edges 13 (one shown in each case). The raw panel 10 comprises a carrier plate core 14 and a print substrate layer 15 (not shown) applied onto the panel upper face 11. Prior to sealing, the panels 10 were provided with complementary retaining profiles 21 and a chamfer 19. The complementary retaining profiles 21 form locking grooves 22 together with opposing panel edges 13. During sealing, the impregnating agent is also applied in the area of the locking groove.
