Carbon Papers for Typewriters are specifically made to give good duplications of impressions when typing manually. In such cases, where the accuracy of documentation is very important, carbon paper plays a very important role. They are mainly found in offices, billing departments, and administration, where it is needed to provide copies of documents without the use of electronic copying techniques.
Certification according to BIS IS 1551:1991 is concerned with the performance and quality of carbon papers to ensure their good duplication capacity. The tests include measurement of clarity of impressions made, strength of ink transfer, uniformity of coating on the surface, and adhesiveness of coating on the surface.
What is IS 1551: 1991
This is the Indian Standard for carbon papers used in typewriters for producing duplicate impressions during typing. It mentions the requirements for coating quality, transfer efficiency, and durability to ensure clear and consistent copies. As per BIS (Bureau of Indian Standards), carbon papers are:
- Evaluated for smudge resistance
- Assessed for impression clarity
- Verified for coating uniformity
- Tested for dimensional stability
