>From my experience using my laser printer and overhead transparencies is that the laser puts down a dot size of a .001" minimum, so the edges of features are usually stepped, which I think would be harder to deal with for this application. Looking at the store bought encoders I have, the features have smooth edges at the maximum magnification I can muster. A larger sensor area and mask could possibly even out the jaggy effect though. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ Virtualization & Cloud Management Using Capacity Planning Cloud computing makes use of virtualization - but cloud computing also focuses on allowing computing to be delivered as a service. http://www.accelacomm.com/jaw/sfnl/114/51521223/ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
