Printing on 100% polyester and 100% polyester performance fabrics can now be printed digitally. Kornit Digital has establsihed a method using existing ink technology and the automatic wetting solution process, that is built into the machines, to accomplish this on light and dark polyester.
Thank you, this is a welcome development. Same inks, same pre-treatment using the same machine, ? What is this special method? Is this a "revision" on the RIP or the software, some sort of a button where you specify if you're using a cotton or polyester fabric? And what will the machine do differently when it's printing on cotton vs polyester (specially on darks)? Will a 932 print differently compared to a 931 or even 933?
There will be a dedicated program developed for each machine series Kornit offers. The Ripping remains the same. This is a process of laying down the ink on the polyester.
When the programs are offically released there will be a selection in the media wizard allowing you to select polyester. Then the machine will lay down the ink in the process automatically.
I talked with one of the senior people at Kornit North America at the ISS Atlantic City Show about the polyester printing. The key is the way the controls on the printer is going to lay down the ink. The production times are not going to be as fast as printing on to cotton, but it will provide a great way for doing some of the sports / team uniforms and printing on dark wicking fabric. I was told the release would be at the Digital FESPA Show in Amsterdam in about two months. It will be interesting to see how the prints hold up. I have heard the ink will stretch with the garment - which is a great feature.
The print on the polyester is 100% washable and stretchable. The process takes longer per print than a regular Kornit print but the automation will make this applicable to short run, high added value garments.
Amsterdam is the offical introduction of the process to the industry.
Not necessarily. If could just lay down the same amount of ink in a much slower fashion allowing the ink to congeal before the rest of the ink is dropped. Or it could lay down less or more ink. There are still a lot of questions out there about printing on to polyester with a dtg printer. Hopefully, they will be answered in a couple of months.
As with any printing, each manufacturers product must be tested for dye migration. We have been very successful with the major brands of 100% polyester. Starter brand reds for instance, have a high rate of dye migration while Champion work fairly well. The best answer is to provide Kornit with a sample to test first hand.
If you print digitally on Polyester, it is important to cure at a lower temperature. The household dryer should also be set a lower temperature, but it can be dried as normal.
Once the programs are complete they will be available at no charge to our customers.
An announcement will be sent to all customers inquiring if they will want this option installed.

Thats great....thanks for the update...count me in!
I saw the Kornit printing on polyester in Amsterdam (FESPA Digital). Printing takes 2 minutes longer than usual. Print 1st white and wait 60 seconds, then print the 2nd white and wait 60 seconds again. Thereafter, the Kornit printed colors.
The results were very good. But one reason or another, there were some pieces of unequal Prints.
