Eco Form Computer Form 9.5″ X 11″ – 2up

Computer form is paper which is designed for use with dot-matrix and line printers with appropriate paper-feed mechanisms. Other names include fan-fold paper, sprocket-feed paper, burst paper, lineflow (New Zealand), tractor-feed paper, and pin-feed paper. It can be single-ply (usually woodfree uncoated paper) or multi-ply (either with carbon paper between the paper layers, or multiple layers of carbonless copy paper), often described as multipart stationery or forms. Continuous stationery is often used when the final print medium is less critical in terms of the appearance at the edges, and when continuously connected individual sheets are not inconvenient for the application. Individual sheets can be separated at the perforation (leaving a slight serration), and sheets also have edges with punched holes, which also can be removed at the perforation (one typical format).

Uses

1.Printing

Printing on continuous forms was at one time the basis for many business operations, not the least of which the direct mail industry. Reader’s Digest and Publisher’s Clearing House relied heavily on these forms to promote their products (most often via sweepstakes), issue billing, address form letter correspondence, and manage their own business data needs. Continuous form paper is used in some of the fastest types of printing systems, some of which print text at a rate of 20,000 lpm (lines per minute). This will produce about 400 pages per minute, using about 8-11 large boxes of paper for every hour of printing (affected by character density, and other details such as paper weight).^[5][6] Direct mail, as an industry overall, has been accused of being environmentally unfriendly, due to a high percentage of the mail being discarded without being read.

2. Decollator

A decollator separates multi-part continuous form paper into separate stacks of one-part continuous form paper and may also remove the carbon paper.

3. Burster

A burster is a machine that separates one-part continuous form paper into separate, individual, sheets along the transverse perforations. A burster was typically used with printed continuous form paper applications such as mass-mail advertising, invoices, and account statements. The machine has two sets of rollers; the first (infeed) runs at a given speed, the second (outfeed) located a specific distance away, running at a higher speed. The first form is gripped by the infeed roller and moves under the second roller. Due to the higher speed, the forms is stretched taut, forcing the perforation against a knife, thus separating the form from the continuous form. The continuous form paper then advances into the feed rollers to burst the next sheet. Bursting is often a high-speed process that allows the continuous form paper to feed in at a steady rate, with burst pages either stacked or fed into a single-sheet conveyance to the next paper processing stage. Burster equipment and paper manufactures had to generate perforation specifications so that the paper perforations reliably separated under the force of pulling the sheets apart and not tear down into the printed part of the sheet.

Large continuous documents might not be split into separate sheets. By continuously folding two single sided printed sheets back-to-back and binding together a stack of continuous form paper along one of the folded edges, it is possible to flip through the stack like a book of double-sided printed pages. With this technique, the stack is normally flipped top to bottom or bottom to top rather than side to side.
