摘要:
A perforated self-adhesive film assembly capable of being imaged includes a perforated face film; a perforated adhesive layer; a perforated liner, each of the perforated face film, perforated adhesive layer, and perforated liner being perforated with a plurality of holes; and a removable non-perforated bonding layer removably attached to the perforated liner. The removable bonding layer includes a bonding surface. The bonding surface includes one or more of the following: i) a surface topography with a difference between the height of a peak and the depth of a trough within one of said plurality of holes of not less than 5 micron, ii) an adhesion enhancing surface coating, or (iii) a surface spaced from said perforated liner around the complete perimeter of one of said plurality of holes.

A partially perforated assembly includes a perforated film layer, a perforated adhesive layer applied to one side of said film layer, a non-perforated overlaminate film layer on the other side of said perforated film layer, and a release liner on the side of said perforated adhesive layer remote from said perforated film layer. When the release liner is removed and the remaining layers of the assembly are applied to a substrate, the remaining layers of the assembly comprise a void network. The void network fluidly interconnects at least two discrete perforation holes in the perforated film and adhesive layers with each other and/or the ambient environment around the assembly so as to facilitate air communication among the holes and/or between the holes and the ambient environment.
摘要:
This invention concerns vision control panels and a method of UV inkjet printing vision control panels. A substantially imperforate light permeable material is partially printed with a ‘print pattern’ comprising a base layer and a design layer comprising a design colour layer. The method is limited to digital UV inkjet printing of all the superimposed layers required to make such panels. Optionally, the method uses a novel printhead array with a novel order of ink color supply and/or novel software to enable the required build-up of ink layers, for example of black, optional silver, white, cyan, magenta, yellow and process black colors. Printing is preferably arranged so that the base layer and design color layer are printed in the minimum number of passes of the printhead assembly of the digital UV inkjet printer to achieve the desired effect, preferably in one pass of the printhead assembly.
