My invention is directed to a novel and em
cient method of and means for registering with
the utmost accuracy, and by optical assistance,
?at bed color printing elements with their ?xed
registry elements.
My invention includes a machine provided
with a lower horizontal support for the printing
elements. an‘ upper horizontal support for the
registry elements, a pair of horizontal bars dis

It is evident that the method of registering the

herein. It is also evident that various changes
may be made in the construction, form and ar
