This item relates to methods of reproducing photos on all forms of material in an era of physical offset printing.The offset method is being replaced by digital transfer direct to the final product,(paper or other porous and non porous surfaces). Newspapers and other "paper" information publications are still producing "hard copies" but these are slowly being phased out. This item was used Circa 1920s in the peek period of paper based media. From the 1940s radio and then television stepped into the mass media revolution.
This book was produced when all printing, Government and private enterprise, was using the "off set" method. This method was used to a great degree in all schools within the Kiewa Valley. It was in an era before "photo-copying machines" were available. This was a period when printing inks for larger printing machines had to be purchased from specialised outlets and printing presses required to be washed after each "run" of printing before the next plate(aluminium) could be fastened onto the "off sett" machinery. Heat infusion now used in large machines and domestic printers has superseded this task.
