This 9 x 11 perf carbonless paper is manufactured by NCR Paper, one of the most widely recognized brands in the carbonless paper industry, and ships in 10 reams of 500 sheets each. The 2-part reverse format pairs a white CB (coated back) top sheet with a canary CF (coated front) sheet below, so a single writing or printing pass produces a clean canary duplicate beneath the white original. The superior perf runs along one edge, creating a controlled tear line that holds the 2-part set together through printing and releases cleanly on separation.
How NCR Paper 9 x 11 2-Part Reverse Sets Work
NCR Paper uses micro-encapsulated coatings on each sheet. The white CB sheet carries the capsule layer on its back surface; the canary sheet carries a reactive coating on its front. When pressure is applied from a pen, an impact printer, or a dry toner laser machine, the capsules in the CB coating break and react with the canary CF coating to transfer a clean image to the sheet below. The carbonless chemistry leaves hands and equipment ink-free, making carbonless paper the industry standard for multi-part form production.
The superior perf on these 9 x 11 sets is designed for precision separation. That superior perf holds the white original and the canary copy together through handling and imaging until the operator tears at the perforation line. Forms can be fanned through quickly after a print run to confirm transfer quality across the set, and the tear is clean enough that separation doesn't damage the printable area. The superior perf position also clears the feed path on offset presses and dry toner laser equipment without interference.
Specifications and Package
The sheet size is 9 x 11, designed for continuous-form layouts and data tables where an 8.5 x 11 sheet doesn't provide enough column width. The weight is 20.5 lb, and this stock ships in a 10-ream package with 500 sheets per ream, for a total quantity of 5,000 sheets per order. Carbonless sheets in this format are ordered in increments of 500, so bulk quantity planning is straightforward.
The CB sheet is coated on its back surface, and the canary CF sheet is coated on its front. Both are smooth-coated for consistent chemical transfer, and the body weight keeps sheets running without curl or misfeeds on longer production runs. The canary and white color coding makes copy routing immediate: the white original stays with the issuing party, and the canary copy serves as the receiving party's return record.
Printer Compatibility and Press Fit
NCR Paper 9 x 11 2-part reverse is designed for dry toner laser printers and offset presses, covering the most common digital and conventional production methods. Dry toner laser printer compatibility means the coated sheets handle toner adhesion without specialty preparation, and the smooth-coated surface supports smooth running through tray feeders on high-speed dry toner laser equipment. Printer compatibility across dry toner laser and offset presses makes this a flexible stock for shops running mixed workflows.
For shops imaging carbonless forms on a high-speed dry toner laser press before binding and distributing sets, this NCR Paper stock is designed for that production sequence. The superior perf clears standard laser equipment tray paths without interference, and the coated body weight maintains registration through the print cycle.
Canary White Sets and Common Applications
The canary white 2-part reverse is one of the most widely used configurations in commercial form production. Canary white is a standard industry pairing for two-part business forms: the white perforated original stays with the issuing department, and the canary copy goes to the receiving party as their record. White perforated sets in this 9 x 11 size are used for invoices, purchase orders, service work orders, delivery slips, and receipts where both parties need identical information from a single printing pass.
For shops producing custom forms, the 9 x 11 sheet provides more horizontal space than 8.5 x 11 products, which is useful for data-heavy layouts on work orders and delivery documentation. Customers who trust NCR Paper for reliable performance know that canary white 2-part reverse sets hold up through manual completion, laser imaging, and offset press runs.

Frequently Asked Questions
What Is the Difference Between Carbon Paper and Carbonless Paper?
Carbon paper is a separate interleaf sheet coated with a pigment layer that transfers an image when pressed between two pages. Carbonless paper builds the transfer chemistry into the sheet using micro-encapsulated coatings, so no interleaf is needed. The result is cleaner copies and equipment that stays ink-free. Carbonless paper is the current industry standard for multi-part business forms. Browse PSD's full range of carbonless paper products to find the right format.
What Is Another Name for Carbonless Paper?
Carbonless paper is also called NCR paper, which stands for “no carbon required.” The abbreviation originally referred to the National Cash Register company, which introduced the first commercial carbonless product in the 1950s. Today, NCR paper and carbonless paper are used interchangeably across the industry, and you'll find both terms on product listings and ordering information throughout the trade.
What Is the Purpose of Carbonless Paper?
Carbonless paper is designed to produce duplicate copies of a document in a single writing or printing pass. The 2-part reverse format is commonly used for invoices, work orders, delivery slips, purchase orders, and receipts where different copies need to return to different departments or parties. The canary white color coding makes each copy's destination clear without additional labeling.
Can You Use a Regular Printer for Carbonless Paper?
NCR Paper 9 x 11 2-part reverse is designed for dry toner laser printers and offset presses, so it works with the most common digital and conventional production equipment. Standard inkjet printers aren't recommended because wet ink doesn't activate the carbonless coating chemistry the way dry toner does.
