Watermark (Watermark) on ASP.NET MVC PDF rotary

Question

Hello, I’m having trouble adding a watermark in a report generated with rotary pdf.

This report has a header, which repeats on all pages and a footer that also repeats on all pages, now I want to make it have a background watermark on all pages, the results I’ve gotten so far was:

1) the mark on top of the printed data, repeating on all pages I tried to use position relative, Absolute and Fixed, with z-index, but it did not work as I would like, part of the report was branded Behind(below) and another part was (In Front).

2) the mark below the data repeating on all pages as the result you would like, but only on the first page, on the second page the mark was printed further to the left of the report repeating part of the image on the right side.

.water_mark {
    background-image: url(../Images/marca-dagua.png);
    background-repeat: repeat-y;
    padding-right:5px; background-size: 80% auto;
}

 <div class="col-xs-12 no-padding-left water_mark" style="">
        <table class="table table-bordered">
    </table>
    </div>

.water_mark {
    background-image: url(../Images/marca-dagua.png);
    background-repeat: repeat-y;
    padding-right:5px; background-size: 80% auto;
    background-position-x: 100px;
}

this is the result code 2.

.water_mark {
    background-image: url(../Images/marca-dagua.png);
    width: 100%;
  height: 1500px; /* TAMANHO DA FOLHA */
  Position: absolute;
  z-index: -1; /* TENTEI OUTROS Z-INDEX */  
}

<div class="water_mark" style="">
</div>
   <table class="table table-bordered">
     </table>

result code 1.

I believe I have a way to pass to the Rotary PDF a background image, but so far I could not get the result, for this reason I tried to solve with css.

Note: the header and footer are made with the rotary through the property: Customswitches as code below.

string customSwitches = "--footer-left \"Versão: " + Versao.NumeroVersao + "\" " +
                    "--footer-center \"Chave de segurança: " + ChaveSeguranca + "\" " +
                    "--footer-right \"Página: [page] de [toPage]\"" +
                    " --footer-line --footer-font-size \"7\" " +
                    " --footer-spacing 5 " +
                    "--header-html  \"" + Url.Action("Header", "PadraoRelatorio", new { area = "", Titulo = "PARA CONSTRUÇÃO" }, "http") + "\" " +
                    "--header-spacing \"5\" " +
                    "--header-font-size \"7\"";
