Ed,

Can you talk about how fast the total process was? Just wondering if the Kornit machine is going to really slow down the automatic press. Would be interesting to know what exactly was done on the shirt by the automatic press and what was done by the Kornit. Thanks.

mark,

i was told this thing can do 200 shirts an hour A4 size !
auto press laying down the white underbase as well as any special effect inks. the kornit laying down the cmyk! yes they are expensive!

Hi Everybody,
This is my first post in this forum, but actually I've browsing for nearly half a year.
Yesterday, I've just came back from Beijing, I've joint the ASGA Exhibition also I've seen the Kornit 933 in action.
Basically, the autopress is use to discharge the dark garment and print CMYK on the 933 unit, the other platens on the auto press give you more choice to print spot color. It seems that it's more industrial and professional.
The sample after discharge and print really give a soft hand feeling, and it doesn't need the white ink.also the curing time is much more faster, it only takes two minitues. For dark fabric, may be the speed is faster than the 931DS.
I'm going to purchase the 931DS, can anybody can give me some figure on the curing process. Such as the electricity and gas consumption, I don't believe the figure that the distributor given to me. I'm appreciated if those the members can give me some valueable information.

So you are saying that the 933 uses DISCHARGE ink? Can anyone else verify this? I am leery of discharge printing in general, and it only has limited use on most garments.

200 shirts per hour? Ed, where did you read this? Or did Kornit put out this information? Because as we know, the 932D can only print about 12-15 darks per hour, and only about 30-35 lights per hour (12 x 10 print size). I know the 931D is faster because there are 256 nozzles per head as oppose to 128, but that at MOST is going to double production figures. I have a hard time believing they can now rip through 200 shirts per hour...... They are using the very same Spectra heads, after all. EVEN if you only count PRINT TIME for the CMYK, and no load / unload time or other such figures, you might be able to get 60-80 prints per hour (CMYK only) with its current configuration. But as always, I'd love to see the thing in action and I'd love to be proven wrong.

Do you happen to know which ink formulation they are using? Because even with the newest formulation of white ink, I would be curious to see how well it adheres to plastisol inks, considering it was formulated to adhere to waterbased inks..... I suppose some testing is in order. Anybody know if this lovely beast will be as the Orlando show this month?

I just thought of one major drawback to this configuration, as well.... One of the key strengths of DTG printing is the ability to create one-offs and short runs. With this setup, you are still required to make underbase screens, and any special effect screens, which essentially puts you into the same boat as anybody screenprinting full color jobs. Sure, you are only making one screen as opposed to 5 or more, but how many of us actually make even ONE screen to print a single t-shirt for a client?

I know most of my business comes from these online shirt designer people who are selling onesies and twosies... I would not be able to compete if I owned a 933. Too much setup and such. There IS a benefit to be able to do medium full color runs, and anything with special effects inks, but if you are that deep into it you might as well opt to make the rest of the screens and run the thing on an automatic - heck, most of the work is in the setup, anyways, and you would boost production through the roof (with or without specialty inks).

for sure...

we were told quite a few settings and we never did see those numbers come true. I am talking about the speed of printing, quantity of prints as well as a few others. But that was only our experience I am sure it has not been the same for others.

I like the idea of the specialty inks being able to be used but I would never go down this path for the same reasons justin listed above. The price is high and the machine is now being put into a pretty rough environment with the screen printing. There are many things you have to watch out for in your environment on the current models so I can't imagine how many more possible issues there will be using this thing right next to your auto.

never know though, they may have created the holy grail... right....

It's real that they're using discharge ink for demonstration. I've talk to the Kornit staff, the answer is crossover T-shirt printing. As we know it's hard to maintain the consistence of the CMYK color by the automatic octopus press. The Kornit 933 printing unit can help to settle the problem, just like the sample photo, the dark shirt is discharge first, then pass the heat unit in order to dry the discharge ink and then print by Kornit 933, when printing, you can't know the final result because all the CMYK ink is printed on a black bkg. The glitter gold is screen print.
After all, the shirt will pass the tunnel gas conveyor dryer to finished the curing process. That's what I saw in the exhibition.

Hi. All

I am new to this forum.

The printer used 4 256 nozzle spectra heads. It can do approx 100-120 A4 per hr currently. The target is to try and push the design to do 200 per hour.

You can either use discharge for the white or screen print waterbased white inks. A special pretreatment has been developed that can be screen printed on prior to the digital printing.

my .2 cents

i would only believe half or less of those numbers unless i was able to watch it in live production for myself.

after experiencing our kornit up close the numbers we were given and that are published are just dreaming unless we are talking about small coverage areas and printing at one of the lowest resolutions.

again, it is just our experience though so take it for what it is... our experience.
