The Principle of Stamp Making with Photosensitive Materials

Photosensitive materials are widely regarded as the most efficient for stamp production due to their unique properties and the precision they offer. Below is a detailed explanation of the process and why photosensitive materials excel in stamp making.

Materials and Tools:

• Photosensitive Pad: Typically gray-black in color, this pad is the core material for stamp creation.
• Transparent Paper: Used for printing the stamp design.
• Photosensitive Machine: Equipped with a flash tube, this machine is essential for the exposure process.
• Ink: Added to the stamp after the process to make it functional.

Process:

1. Design and Printing:
   • The stamp content is designed and printed on transparent paper. The transparency of the paper is crucial as it allows light to pass through specific areas during the exposure process.
2. Alignment and Placement:
   • The printed transparent paper is carefully aligned and placed onto the photosensitive pad. The gray-black color of the pad is essential as it absorbs light efficiently.
3. Exposure in Photosensitive Machine:
   • The assembled materials (transparent paper and photosensitive pad) are placed on the platform of the photosensitive machine.
   • The machine’s flash tube emits light, which passes through the transparent areas of the printed design. The gray-black surface of the photosensitive pad absorbs the light, converting it into heat.
4. Thermal Reaction:
   • The heat generated by the absorbed light melts the surface of the photosensitive pad, creating a barrier layer. However, the areas covered by the printed design (text or图案) block the light and heat, preserving the integrity of the photosensitive material in those regions.
5. Formation of the Stamp:
   • The areas not exposed to light retain their porous structure, similar to the principle of a screen-printing mesh. These pores allow ink to pass through, forming the stamp’s impression when inked.
6. Final Product:
   • Once the exposure process is complete, the stamp is ready for use. Ink is applied to the porous areas, and the stamp can be used repeatedly with high precision and clarity.

Why Photosensitive Materials Are the Most Efficient:

• Precision: The process allows for highly detailed and accurate stamp designs, as the light exposure precisely follows the printed pattern.
• Durability: Photosensitive materials are robust and can withstand repeated use without significant wear.
• Efficiency: The entire process is quick and requires minimal manual intervention, making it ideal for mass production.
• Versatility: Photosensitive materials can be used to create stamps of various sizes and complexities, catering to a wide range of applications.
