Litho Printing: The History and Future of Photographic Prints

litho printing is a printing process that involves a printing cylinder, blanket cylinder, and impression cylinder.

– Stone lithography printing (Alois Senefelder using a stone printing plate in 1796)

– collotype printing (direct printing process, Alphonse-Louis Poitevin in 1856),

– offset printing (indirect printing process),

– di-litho (direct printing process with offset printing plate).

Alois Senefelder invented lithography. In 1796, Senefelder struggled to afford the high cost of printing his plays.

He developed a printing method to make a cost-effective solution that drew an image directly onto a smooth, flat stone surface using a special ink called a "lithographic crayon."

Collotype - (1856-57) can be traced to A.L Poitevin. Continuous tones can be reproduced without screening.

Poitevin developed "heliogravure," a method using a photolithographic process.

Offset printing is a process by which an image is transferred (or 'offset') from a plate to a rubber blanket and then dispensed onto the printing substrate.

Di litho printing is a printing process that involves creating a print by transferring ink from a printing plate to a substrate, such as paper or cardboard.
