is a high quality paper featuring a state-of-the-art microcapsule coating which permits copies to be made without using carbon paper.
Ideal for purchase orders, invoices and other documents requiring the transfer of information from a top sheet to multiple sheets beneath.
carbonless paper is compatible with letterpress, dry and wet offset and flexographic printing. It is also suitable for inkjet printing on most inkjet printers and has been used successfully on some laser printers. However, it is recommended that users conduct their own tests to establish suitability and optimum settings on target printers.
offers production advantages to printers:
Advantages of using carbonless paper:
Copies are made by the reaction of two separate coatings under pressure (from a pen, impact printer, typewriter, etc). One coating, CB (or coated back) consists of pressure sensitive microcapsules. Under pressure, these capsules rupture, releasing a special fluid that triggers a colour reaction on the coated underlying sheet CF (or coated front). The CF coating provides a highly absorbent layer which creates a sharp, intense copy image.
There are 3 grades of carbonless paper:
CB
The original or top sheet of a multi-part form with a pressure sensitive, ink-releasing microcapsule layer on its underside.
CFB
The pressure sensitive intermediate sheet(s) of a multi-part form which both receives (ink-absorbing) and transfers (ink-releasing) an image. This is the most sensitive sheet of a multi-part set.
CF
The bottom copy of a multi-part form which receives an image. Not pressure sensitive and can be handled as normal paper.
For the completion of self separating cut sets, such as purchase orders, invoices and transportation documents, always use Fanapart Adhesive which is a solvent-free glue specially designed for the range of papers.
The adhesive works on the principle of greater absorption between two coated surfaces. Where there are no coatings, such as between the underside of the CF and the upper side of the CB sheet, separation will occur to give individual sets.
Instructions for use:
The grain direction of the sheets must be consistent within a form set. As a rule, the grain direction should be parallel to the glued edge.
Preferably guillotine a skim-trim from the edge to be glued and have a margin of at least 2mm free of printing ink.
Align the stack carefully at the edge to be glued especially where the top or bottom sheets are heavyweight qualities.
The stack height should not exceed 30cm.
A heavy weight to press the stack down is not necessary. In order to prevent gaps between the sheets, place a wooden board across the full width of the edge of the stack with a weight on top of it. Use a maximum 2kg weight for a 30cm stack. (The purpose of the weight is to avoid the upper sets moving during gluing and not to compress the stack).
Shake adhesive bottle well before use.
Apply as soon as possible after trimming.
Never return unused adhesive back into the adhesive bottle.
Apply adhesive using a flat, soft, clean brush of 50-60mm width. Work from the middle of the stack outwards using horizontal strokes.
Saturate the glued edge by applying several wet on wet coats in one single operation.
NB: Thick layers of adhesive do not impair the separation of the stacks and have a positive effect on the strength of the glued connection.
Allow to dry at room temperature for approx 30 minutes before separating the sets into small stacks by fanning them out.
NB: For better separation, remove the weight after 15 minutes drying time.
The adhesive will be completely dry after 60 minutes.
Top Tips:
carbonless paper is versatile and easy to customise. For use with letterpress, offset and flexographic printers. Although not specifically designed for use on laser printers, it has been successfully used, achieving good results. It is also suitable for inkjet printers.
offers flexibility to save on costs by creating your own multi-part forms in-house. Ideal for producing high quality, short run business forms on-demand. Advantages include:
Suitable for a wide range of applications:
Whether you require straight or reverse pre-collated sets will depend on your type of printer; how you load the paper tray and how the printer outputs printed sheets. Use the following guide to help you select the correct collation of forms for your printer.
We would recommend that if you are in any doubt, you should conduct testing on your printer to determine which product is right for you.

pre-collated sets are only available as REVERSE sets. If your printer requires STRAIGHT collated, click here for our Xerox range of pre-collated straight sets.
Sets stick together?
Poor separation – blocking
Ensure correct collation.
Use Fanapart Adhesive.
Reduce weight applied on stack during drying.
Reduce quantity of glue on second coat.
Ensure no more than 30 seconds between coats of glue.
Sets fall apart?
Poor bonding
Use maximum 2kg weight for 30cm stack.
Apply more glue with first coat.
Allow longer natural drying time.
Clean guillotine knife.
No copy?
Sheets upside down
Wrong grade used
Check before printing and collating. Check collating sequence.
Poor copy intensity?
Damage to CB
Compare with unprinted paper.
Reduce impression pressure to minimum.
Use compressible blanket.
Discoloration?
– Lines
Damage to CB
Adjust pressure of lay on wheels or move – Lines to edges.
Discoloration?
– Overall
Damage to CB
Reduce blanket to impression cylinder pressure.
Discoloration?
– Guillotine clamp marks
Damage to CB
Check for gutter/channel mark. Check knife angle. Use softer clamp material.
