This reacts with the coating on the front of the sheet beneath, instantly producing an identical copy.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The process happens automatically as you write, with no separate carbon sheet required.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Is CB Paper?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>CB (Coated Back)<\/strong> paper is always the <strong>top sheet<\/strong> in an NCR set.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It has a normal writing surface on the front, while the back is coated with microscopic capsules containing a colourless dye.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When you write on the front of the CB sheet, pressure causes the capsules on the reverse to burst, transferring the writing onto the sheet below.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Is CFB Paper?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>CFB (Coated Front and Back)<\/strong> paper is used as the <strong>middle sheet<\/strong> in multi-part NCR forms.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It has:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A receiving coating on the front.<\/li>\n\n\n\n<li>Colour-forming capsules on the back.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This means it performs two jobs:<\/p>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li>It receives the image from the sheet above.<\/li>\n\n\n\n<li>It passes the image onto the sheet below.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">If four or five-part NCR forms are required, additional CFB sheets are added.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Is CF Paper?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>CF (Coated Front)<\/strong> paper is always the <strong>final sheet<\/strong> in the set.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Unlike the other sheets, it only has a receiving coating on the front and no coating on the back.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Its job is simply to receive the final copy of the writing.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Which Paper Is Used in 2-Part NCR Pads?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A standard <strong>2-part NCR pad<\/strong> consists of:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Sheet<\/th><th>Type<\/th><\/tr><\/thead><tbody><tr><td>Top<\/td><td>CB<\/td><\/tr><tr><td>Bottom<\/td><td>CF<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">When you write on the top <strong>CB<\/strong> sheet, the information is automatically transferred to the <strong>CF<\/strong> sheet below.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Because there is only one copy, a <strong>CFB<\/strong> sheet isn&#8217;t required.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Which Paper Is Used in 3-Part NCR Pads?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A standard <strong>3-part NCR pad<\/strong> consists of:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Sheet<\/th><th>Type<\/th><\/tr><\/thead><tbody><tr><td>Top<\/td><td>CB<\/td><\/tr><tr><td>Middle<\/td><td>CFB<\/td><\/tr><tr><td>Bottom<\/td><td>CF<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">When you write on the top <strong>CB<\/strong> sheet, the information is automatically transferred to both the <strong>CFB<\/strong> sheet and the <strong>CF<\/strong> sheet, creating two identical copies.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Which Paper Is Used in 4-Part NCR Pads?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A standard <strong>4-part NCR pad<\/strong> consists of:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Sheet<\/th><th>Type<\/th><\/tr><\/thead><tbody><tr><td>Top<\/td><td>CB<\/td><\/tr><tr><td>Second<\/td><td>CFB<\/td><\/tr><tr><td>Third<\/td><td>CFB<\/td><\/tr><tr><td>Bottom<\/td><td>CF<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">When you write on the top <strong>CB<\/strong> sheet, the information is automatically transferred through each <strong>CFB<\/strong> sheet before reaching the final <strong>CF<\/strong> sheet, creating three identical copies.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Available Paper Colours<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Carbonless NCR paper is available in a range of colours, allowing you to easily identify each copy within a set or match your own filing system.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Standard NCR paper colours include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>White<\/li>\n\n\n\n<li>Yellow<\/li>\n\n\n\n<li>Pink<\/li>\n\n\n\n<li>Green<\/li>\n\n\n\n<li>Blue<\/li>\n\n\n\n<li>Chamois<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The paper colours themselves do not affect how the NCR paper works, they simply make it easier to distinguish between the different copies.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you require a specific colour that isn&#8217;t available as a standard carbonless paper, we can often achieve the desired appearance by printing a <strong>100% colour wash<\/strong> onto a white sheet, providing greater flexibility while retaining all the benefits of carbonless paper.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Is CB, CFB and CF Paper the Same Quality?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In most cases, yes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">On <strong>sheet-fed printing presses<\/strong>, all parts are typically produced using <strong>75gsm or 80gsm<\/strong> <a href=\"https:\/\/www.ncrpads.co.uk\/blog\/carbonless-paper\/\">carbonless paper<\/a>, so the only difference between the sheets is the coating applied to each one.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, <strong>reel-fed (web-fed) printing presses<\/strong> use different paper weights, such as <strong>80gsm \/ 60gsm \/ 57gsm and 53gsm<\/strong>. This helps improve handling and performance during high-speed production.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Regardless of the paper weight used, each sheet is specifically designed to work together to produce clear, legible copies throughout the NCR set.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Frequently Asked Questions<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Can you print on all the sheets?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes, all sheets can be professionally printed with your logo, company details, terms and conditions, numbering and other information.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can NCR paper be numbered?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes, sequential numbering is one of the most popular options for <a href=\"https:\/\/www.ncrpads.co.uk\">NCR pads<\/a>, books and sets.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can I mix paper colours in the same NCR set?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes, NCR paper is available in a range of colours, allowing different copies to be easily identified. The paper colours can usually be arranged in the order that best suits your business requirements.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What does CB, CFB and CF stand for?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">CB stands for Coated Back, CFB stands for Coated Front and Back and CF stands for Coated Front. These coatings allow pressure applied to the top sheet to transfer writing through the NCR set without the need for traditional carbon paper.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Need Advice on Choosing the Right NCR Paper?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Whether you require <strong>2-part<\/strong>, <strong>3-part<\/strong> or <strong>4-part<\/strong> NCR pads, books or loose sets, we&#8217;re here to help.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you&#8217;re unsure which paper combination is right for your application, <a href=\"https:\/\/www.ncrpads.co.uk\/contact.php\">get in touch<\/a> with our friendly team.
