Letterpress Printing is the "godfather" of printing. It is the oldest printing technique. Right after the Gutenberg Press popularized movable type back in the 15th century, letterpress had been the predominant printing technique for five centuries.
In this method, a surface area with elevated letters is inked and hard-pressed to the top of the printing substrate to recreate a text or an image in reverse. To produce an impression, letterpress printers had to construct individual letters and characters into a "forme", secure them into a printing chase, and ink the type using a roller. A sheet of paper is placed over the inked type and slid beneath the press. A subtle pressure or force is then exerted by manually securing the screw. The ink will soon be migrated from the type (metal or wood) to the paper.
"The entire process of letterpress printing involves four phases"
> Composition
> Imposition
> Lock-up
> Printing
Offset Printing screen printing is a form of stenciling that initially gained popularity in China during the Song Dynasty (960-1279 AD). The technique was then adapted by neighboring countries – more specifically, Japan – and was further developed by incorporating more sophisticated approaches
The main advantage of screen printing is the fact that the top of the print recipient doesn't need to be leveled or flat. Also, the ink can stick to several materials like paper, fabrics, glass, wood, metal and even ceramics. As a result, screen printing is typically used various industries, which include:
> Party supplies (balloons, latex decors)
> Clothing
> Healthcare tools
> Decals
> Product labels stickers
> Signage
> Billboard displays
> Film and TV technology
> Sports graphics
> Printed electronics
> Fabric and textile
