An automatic printing machine including an automatic plate loading device wherein a water duct mechanism is first activated after which a form roller mechanism is operated to cause form rollers to contact a plate cylinder. After this, the plate loading device forms a plate loading operation in which an original plate is satisfactorily fitted onto the plate cylinder wherein the plate surface is prevented from being contaminated by ink. Satisfactory printing results are obtained as soon as the plate is loaded onto the plate cylinder so that the first printing sheet is satisfactory and there is no waste of printing sheets.
