Within my email I have a 1 pixel transparent pixel acting as a seperator between 2 pieces of copy. I have given the td a background colour. The line is rendering perfectly except on Apple devices, where the line appears thicker. I have used the code below. Has anybody experienced this and does anybody know a work around? Thank you.

<tr>
    <td>
        <table width="580" border="0" cellpadding="0" cellspacing="0" align="center" class="deviceWidth">
        <tr>
            <td height="1" align="center" style="background-color:#BEBDBD; padding-left:40px; padding-right:40px; line-height:1px; font-size:1px;">
                <img src="images/trans_pix.gif" height="1" alt=" " class="splitter">
            </td>
        </tr>
        </table>
    </td>
</tr>
