Carbon Paper : What is it?
Carbon paper is essentially paper coated with a thin layer of loosely bound pigment or ink on one side, and bound with wax. The carbon paper is placed between the original and a blank sheet where the document is to be copied onto. As the user types or writes on the original, the pressure from the typeface or pen deposits the ink on the blank sheet, thus creating a 'carbon copy'.
With the advent of photocopiers and printers, carbon paper has had limited use. Today, it is rarely used for making copies of typewriting and handwriting, but it is still being used where instant copies of the original are needed: receipts at points of sale, on-the-spot fine notices, money orders, duplicate checks, and tracking slips.
Kinds of Carbon Papers include the following:
|Free flowing carbon|
- During assembly, the free flowing carbon paper is coated with a narrow clear-edge and inserted between the areas where the glue lines or crimps are aligned.
- It is cutoff or cross perfed after the form is assembled completely.
- The sheet length is adjusted by tension controls on the collator while feeding.
- It is the simpler way of producing carbon paper.
- Processed carbon is installed in the register with the cross perf of the form.
- It can either be simply processed carbon or pattern carbon.
- The processed carbon has line holes, bindery functions, and cross perfs.
- The pattern carbon has line holes and the carbon is printed in blank areas.
|Visibility: Look for carbon paper that has a thicker layer of ink or pigment for more visibility; however, make sure that the ink does not easily smear when transferred onto paper. |
