Letterpress is the earliest printing method. This process reproduces an image in reverse by inking and pressing a surface with raised letters onto the printing substrate. Traditionally, metal type has been utilized, although carved wood or stone blocks are viable alternatives.
After the introduction of moveable type by the Gutenberg press in the 15th century, the letterpress dominated the printing industry for the next five centuries. Massive rotary presses made industrial publishing and newspaper manufacturing feasible.
In the 1950s, xerography and printing services began to replace letterpress, and by the end of the 20th century, digital printing and associated technologies had become the norm for many applications.
However, letterpress is still employed for some specific business uses. Modern lovers who value the hand-made features and historical essence of letterpress print are also reviving the ancient process.
Letterpress printing system
Johannes Gutenberg, a German-born in 1400 and died in 1468, created letterpress printing. He bequeathed our civilization one of the most significant innovations in history.
There were numerous difficulties in getting knowledge to lower-income strata in the fifteenth century, so the discovery of letterpress printing was significant. It made it possible for the information to reach many people at a high cost.
Initially, letterpress was performed on platen presses, in which the paper was pressed against the flat, smudged form by a flat platen; afterward, the platen was replaced by a roller in the flat-bed cylinder press; and later still, the printing form was wrapped about one cylinder, and the paper was allowed to pass between this cylinder and the printing shape.
Types of letterpress machines
Flat machines, cylindrical flat machines, and cylinder machines are the three primary types of letterpress machines.
Flat machines: In the earliest letterpress machines, the paper and the plate are positioned on a flat surface. They are simple to handle and utilize, and their adaptability is touted as their biggest asset.
Flat, cylinder-shaped machines: The plate remains on a level surface, while the paper is positioned on a cylinder that moves the plate. After modification, they may be utilized for cutting and even folding.
Cylinder machinery: The plate and the paper are positioned on cylindrical surfaces for cylinder machines. One of the benefits of this machine is sending the paper through two different cylinders, therefore producing two different printing colors simultaneously.
The benefits of letterpress printing
- After an initial expenditure of a rather large amount, it is not required to incur considerable further excessive costs.
- Unlike other methods or printing processes, it is possible to customize the prints and receive them with more distinct and distinct relief.
- Letterpress printing allows for diverse paper types (such as cardboard and offset paper, among others), which might be difficult with other printing methods.
Letterpress printing procedure
Depending on the type of letterpress machine used, the printing process may vary slightly; nevertheless, in general, the letterpress printing process may be explained in three steps:
- The initial step involves preparing the letterpress printer; within this procedure, the following threads can be identified: Assembly or composition of the plate, a process consisting of the addition and subordination of the types. Then, the plate and paper should be loaded into the printer in the same position as the printing rollers.
- Next, we apply ink to the printer as the second step (specifically in the ink rollers). Typically, a specialized spatula is employed for this procedure.
- The final stage is letterpress printing on the specified paper. During this portion of the process, ink is put to the types of the plate, and the image is imprinted on the paper as the cylinders roll over it (by the pressure between the plate and paper generated by the cylinders).
It is crucial to note that the letterpress printing method described above is a generality. It means that, based on the machine and paper used, the procedure may vary slightly.
