What is a press sheet of stamps?
A press sheet of stamps, also known as a press proof or a plate proof, is a sheet of stamps that is printed from the same plates used to print the regular postage stamps. These sheets are typically produced during the stamp printing process to ensure the quality and accuracy of the final product. Press sheets are highly sought after by stamp collectors and enthusiasts due to their rarity and unique characteristics.
In the early days of stamp printing, press sheets were used as a quality control measure. Today, they are considered valuable collectibles due to their limited availability and the information they provide about the printing process. Each press sheet contains a grid of stamps, which can vary in size depending on the design and the printing press used.
How are press sheets different from regular stamps?
The main difference between press sheets and regular stamps lies in their purpose and the way they are distributed. While regular stamps are intended for use in postage, press sheets are typically not meant for mailing. Instead, they are used for the following purposes:
1. Quality control: Press sheets allow printers to inspect the stamps for any errors or defects before they are released to the public.
2. Design verification: They help designers and printers ensure that the final product matches the intended design.
3. Historical documentation: Press sheets provide a tangible record of the printing process and can be valuable for historical research.
4. Collecting: Stamp collectors prize press sheets for their rarity and the unique information they offer about the stamp’s production.
Types of press sheets
There are several types of press sheets, each with its own unique characteristics:
1. Full sheets: These sheets contain the entire printing plate and are often the most valuable. They can be further categorized into different varieties, such as the full sheet with selvage (the edge of the sheet) and the full sheet without selvage.
2. Half sheets: Half sheets are exactly half the size of a full sheet and contain half of the printing plate. They are less valuable than full sheets but still sought after by collectors.
3. Quarter sheets: These sheets are one-quarter the size of a full sheet and contain one-quarter of the printing plate. They are the rarest and most valuable type of press sheet.
4. Die proofs: Die proofs are small sheets that contain a single stamp or a few stamps from the printing plate. They are often used for design approval and are highly prized by collectors.
Collecting press sheets
Collecting press sheets can be a rewarding hobby for stamp enthusiasts. Here are some tips for those interested in starting a press sheet collection:
1. Research: Learn about the different types of press sheets and their values. This will help you identify rare and valuable items.
2. Condition: Like regular stamps, press sheets should be well-preserved. Look for sheets with minimal creases, folds, or other damage.
3. Authenticity: Ensure that the press sheets you collect are genuine. Counterfeits exist, so it’s important to purchase from reputable sources.
4. Variety: Try to collect a variety of press sheets, including different types, designs, and denominations.
5. Join a club: Consider joining a stamp collecting club to connect with other enthusiasts and learn more about the hobby.
In conclusion, a press sheet of stamps is a valuable and unique collectible that provides insight into the printing process and the history of stamp production. Whether you are a seasoned collector or just starting out, press sheets can add excitement and depth to your stamp collection.
