<p>[QUOTE=&quot;mikediamond, post: 2778149, member: 1859&quot;]Interesting effect.&nbsp; The letter B is smeared north-to-south and south-to-north.&nbsp; This may be true of the E as well, although the primary direction of movement is north-to-south.&nbsp; This most closely resembles the form of machine doubling known as &quot;slide doubling&quot;.&nbsp; I have noticed that some grease strikes are associated with smearing of the design, so this may have been a contributing factor.&nbsp; Exactly how it contributes is unclear.[/QUOTE]</p><p><br /></p>
