Print Registration Gauge

      Disclosed is a portable registration gauge for use in
accurately reading the printed registration lines on a print or copy.
This device has the accuracy of an eye loop, the ease of use of a
scale, and is very user friendly.

      The gauge, as shown in Fig. 1, uses a cam 10 which has a
graduated scale of radius distances around its periphery. The cam 10
is rotatably mounted to a base 12 which includes a stop 14 against
which the sheet being measured is placed. A magnifying lens 16 is
positioned above the cam 10 and includes a reference line 18 scribed
on the bottom of the lens.  Fig. 2 shows a sheet of paper 20 in
position for having the location of the registration line or mark 22
measured with respect to the sheet edge 24.

      To use the gauge, the paper 20 is placed under the cam 10 and
against the edge stop 14.  Next, the cam 10 is rotated until the edge
of the gauge is aligned with the desired mark.  The corresponding
reading on the cam indicates the distance, in millimeters, between
the mark and the paper edge. Other cam graduations are possible,
including graduations starting at zero when a measurement may be at
the edge of the paper.  In Figure 2, the cam needs to be rotated
farther in a clockwise direction before the edge is aligned with the
line on mark 22.

      A modified version of the disclosed gauge can be used for
measuring dimensions from the center of the paper.  In such case, the
cam could be mounte...
