The new imagePROGRAF iPF6400S and iPF8400S are designed to support high-volume production. Both feature new 'Hot Swap' ink capability to allow for uninterrupted printing and the same kind of new colour-density sensor found in the iPF9400S, which was launched last September.

Features on the two machines, which replace the iPF6300S and iPF8300S, ensure users in production, proofing, photographic and design industries receive uninterrupted printing across the full range of 24" to 60" eight-colour models, according to the manufacturer. The list prices for the iPF6400S and iPF8400S are £2,495 and £5,395 respectively.

Canon UK business imaging spokesman Will Tomlins said the Hot Swap ink capability was a "stand out" feature.

"Customers get much better image quality," he said. "The hard disk has also been increased from 160GB to 250GB, so users are able to store a greater number of files and reprint them without resending from a PC. This is great for graphic arts and creative industries."

Canon UK wide-format group director Duncan Smith said: "The upgrades designed to enhance image quality, productivity and usability. These latest updates reflect this feedback from customers and enable us to offer even stronger and more versatile products."

IPF6400S features an optional spectrophotometer to support high-precision colour management, while users can conduct colour verification and create colour profiles automatically.

Extras include automatic nozzle compensation, email error reports, consumable replacement notifications and a larger optional 300ml ink tank.

Both devices are commercially available now.
