Did You Know?Reacto carbonless paper - how does it work?

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 Reacto Carbonless paper logo carbonless paper:

Reacto carbonless paper
Carbonless Paper CB

CB
The original or top sheet of a multi-part form with a pressure sensitive, ink-releasing microcapsule layer on its underside.

Carbonless Paper CFB

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.

Carbonless Paper CF

CF
The bottom copy of a multi-part form which receives an image. Not pressure sensitive and can be handled as normal paper.

How to use it?Reacto Fanapart Adhesive - How to use it

Reacto adhesive

For the completion of self separating cut sets, such as purchase orders, invoices and transportation documents, always use Reacto Carbonless paper logoFanapart Adhesive which is a solvent-free glue specially designed for the Reacto Carbonless paper logo range of papers.

Carbonless Paper CB

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:

Carbonless Paper CB

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.

Carbonless Paper CB

Preferably guillotine a skim-trim from the edge to be glued and have a margin of at least 2mm free of printing ink.

Carbonless Paper CB

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).

Carbonless Paper CB

Shake adhesive bottle well before use.

Apply as soon as possible after trimming.

Never return unused adhesive back into the adhesive bottle.

Carbonless Paper CB

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.

Carbonless Paper CB

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 Tip

Top Tips:

  • If stored at room temperature (20-25°C), Reacto Carbonless paper logo adhesive can be used for up to two years. However, it is recommended to use within one year.
  • Before unwrapping the paper and commencing printing, always acclimatise the paper to the conditions of the printing room/area.
  • Adhesive that has been exposed to frost will no longer work.
  • Before gluing a large number of sets, carry out a test gluing.
  • If using higher grammages of paper to make sets, apply a second coat of adhesive approx 1 minute after the first coat.
  • Hot air drying affects the gluing; wait 10 minutes before switching on.
  • Any warping of the stacks at the glued edge will not be permanent and will disappear after a short time.
  • After use, always clean the brush with water.
  • When using guillotine-type cutters, the following must be observed:
    • Keep the press-bar pressure as low as possible.
    • Slipping of the stack and discoloration can be avoided by attaching a section of expanded rubber to the press bar.
    • Distribute the stacks evenly over the width of the cutter, a height of the stacks of 8-12 cm is recommended.
    • Remove protection sheets before cutting the reams.
    • Use a blade angle of 19° to 21°.

ApplicationsFAQs

  • Is Reacto Carbonless paper logo environmentally friendly? Recycle logo
    Yes - Only high-grade ECF bleached pulp from FSC and/or PEFC certified suppliers is used to make reacto carbonless paper. The manufacturing process is centred on minimising waste and recycling or utilising residual materials in an eco-friendly manner.  All raw materials are selected according to their environmental sustainability ie. how well they biodegrade and can be recycled, in addition to health and safety aspects.
    Reacto packaging is 100% recyclable.
  • What printers can Reacto Carbonless paper logo be used on?
    Reacto can be printed using any of the usual methods for printing forms ie. letterpress, dry and wet offset and flexographic printing. It is not specifically designed for use on laser printers but has been successfully used, achieving good results. It is recommended, however, that users should perform their own tests first to establish suitability and check dimensional stability and the toner’s adhesion on the front of the CB sheet.
    reacto can also be used on inkjet printers. However if the quality of the printed copy must meet demanding requirements, it is advisable to conduct testing beforehand to confirm suitability.

  • What type of ink should be used to print on Reacto Carbonless paper logo?
    High quality, low tack printing inks should be used, preferably unthinned. However, when printing on the reverse side eg. Terms and Conditons, use thinly applied light-coloured inks (not glossy) to prevent show through.
    Printing solid block imagery on the reverse side of the top and middle sheets should be restricted to areas in which no legible copy image is required, as toner can create a barrier preventing or impairing the image transferral. Halftone printing techniques impair the quality of copies if the dot density exceeds 25%.
  • Is Reacto Carbonless paper logo suitable for perforation?
    Yes - reacto carbonless paper is suitable for longitudinal, transverse and remaliner perforation.
  • What is the copy life of Reacto Carbonless paper logo carbonless paper?
    Reacto is officially tested and approved to meet the legal requirements laid down for the storage of business records. Tests have shown that archiving times of more than 25 years are achieved using typical filing or folder systems.
    The copying properties of reacto remain virtually unchanged for up to three years. For optimum results however, reacto forms should be used within five years.
    To optimise length of storage, reacto forms should not be exposed to chemicals, vapours, fumes or bright light. Plasticisers contained in plastic films and sheets can impair copies therefore polyethylene products are recommended.
  • What is desensitising ink used for?
    For some applications such as data-mailers, you may not wish the image copy to be seen on specific parts of the form. There are two main ways to achieve this, either blocking out using a scramble pattern, or by printing desensitising ink onto the area in question.
    Desensitising Ink is specially developed to prevent the chemical reaction between reacto CB and CF coatings rather than acting as a physical barrier. The application is frequently used in medical and finance applications where confidentiality is sought, so certain information is only available to selected parties.
    Reacto desensitising ink is specially formulated to work with reacto CF sheets.
