Printing is an old art. It has a number of forms and types. One of the most ancient types of printing that is in practice for years are known as the letterpress. It is a creative way of adding the text to the paper. The movable text has an elevated look. These elevated alphabets in the text are thoroughly inked and then they are fixed strongly against the required surface. The process is also referred as relief process. A specially designed plate is used to print the image. The text area of the plate is a little raised as compared to the non word area of the plate so that the image at the end is clear and easy to read.
The letterpress printing is possible in only one color. It is a tough job to have multiple colors used in the images while printing and this is because the inking system is not very reliable. It is only the seasoned and well versed printer who can actually do the task of great letterpress printing NYC in the letterpress. Although a number of technical innovations have been added to the letterpress printing but it still requires a great deal of expertise.
The letterpress printing is classified into different categories depending upon the kind of equipment and technique used for printing. In this regard the letterpress printing is classified into three broad categories being rotary printing, wedding invitations NYC and the flat bed cylinder printing.
Rotary letterpress printing
It is further subdivided into two more types that are the sheet fed printing and the web fed printing. The name rotary indicates that in each type the basic concept is the rotation. In the former type of the rotary letterpress a plate is attached to the cylinder. It is further added with a roller system that adds ink to the part of the plate that is comparatively little elevated than the rest of the plate. As the paper slides through the two cylinders while they are in continues rotation the ink added to the images makes impression on the paper thus making the text visible on the paper. In the latter type of the rotary printing that is the web fed printing the newspapers are printed. The only difference between the two forms of the rotary printing is that in this case instead of the single sheets passing through the cylinders a continuous web of papers is passed from between the plate cylinder and the impression cylinder the rotary printing is a commercial technique used for printing the newspapers and magazines.
Platen letterpress printing
This kind of press printing includes two plates. These two plates are referred as the bed and the platen. The substrate that needs to be printed is actually added to the platen. The image is then fixed to the flat surface. After adding ink to the plate the image is placed on another bed and pressed with the inked plate. The printing is then completed. The process is extremely advantageous in case of the limited areas like the invitation cards. The extensive version of the platen letterpress printing is used for embossed printing.
Flat bed cylinder letterpress printing
This system comprises of two different plates in two different directions. One of the plates that are fixed with the bed first gets covered with the ink and then it moves over the substrate. The substrate is then allowed to move around the impression cylinder. It is possible to have the prints in either one color or even in dual colors. The process is time consuming and much slower than the rest of the two procedures. It is a good choice for printing letterheads and business cards.
