relative to the blanket cylinder 14 is possible to allow for the particular thickness of the web or sheet substrate passing therebetween accordingly the pneumatically actuated and controlled roller and cylinder adjustment system 90 a b and 190 permits the elimination of mechanical stoppers which have typically been used in the past to locate the form rollers relative to the plate cylinder and the impression cylinder relative to the blanket cylinder the form roller and cylinder adjustment systems 90 a b and 190 provide the ability to throw on or off the form rollers 28 30 and the impression cylinder 16 and further permits more accurate adjustment of the contact stripe it also enables the positioning of the form rollers 28 30 and impression cylinder 16 as required regardless of the plate and blanket cylinder size used although pneumatic actuators were described as being the preferred kind of actuator for the adjustment systems 90 a b and 190 it is understood that other appropriate kinds of actuating members may be used such as hydraulic or electric linear actuators for example particularly in one alternate embodiment of the present invention the first pneumatic actuator 192 is alternately a ball screw actuator if hydraulic actuators are used hydraulic fluid pressure would have to be adjusted to obtain the desired contact stripes also the adjustment systems as described herein can be used to similarly adjust other rolling elements in the printing press as required the embodiments of the invention described above are intended to be exemplary those skilled in.
