Colin,
the post wasn't meant to rattle your cage, and I apologize if your taking it that way. I was simply answering marcs question on the differences. I have much respect for David very smart guy and a nice guy as I said in my post. (Trivial)meaning most profiles can be produced in house if you have the knowledge to do so... I wasn't referring to any printer brands only the rip technology and everyone knows what works best for them. Im simply saying there is little substitute for the white ink jell time if your after the highest quality, brightest prints possible with the current technology. Imho!

Jeff, you changed your post to cover yourself !!. Everyone can see this.
Zak's point is very true, using this forum to belittle anything Neoflex does not do or supply gives the company a very un-professional image.

You don't need to apologise to me, its water off a ducks back.

The Brother system is not the same as the Epson, as you have a separate print head for the white from the color and it is physically offset from the color (with a gap).
So the Brother doesn't have to split nozzles and can have a bigger gap (same as Mimaki 3042 UV)

Jeff if you have found profiling T-shirts easy you are a better man than me, as I have never found it easy. I am still developing better techniques.
White shirts are one thing, but you still have to read 1000+ color swatches off a shirt and that isn't that easy without the right know how and equipment.
When you get to black shirts it gets even more complicated.

The single pass printing that has been around for the last few years in DTG, prints the white and color together and they mix immediately on the media, the problem was this gave a lot of washed out colors and so wasn't something you could really use with any job, only certain types depending on the shirt and colors in the design.
We actually split the print head and control which nozzles are used channel by channel, this was anything but a trivial development and while there are other RIP's (such as the Kathari RIP used by Neoflex) that have the ability to do software microweaving, I am not aware of any of them having the ability to control which nozzles get used channel by channel as we do and certainly not seen anyone else doing this on an Epson. That doesn't mean they cant develop this, its just that as far as I know they haven't yet.
But I am sure they will be working on it soon.
However certain products from Roland, Mimaki and Epson do have this built into the printer firmware on the large format machines, so the concept isn't new.

Jeff is correct that we originally developed this for the R2000 and DCS UV printing, I was extremely dubious about how well this would work for DTG, due to the issues of getting the white to settle before printing the color and I was pleasantly surprised how well it did work (better than I expected) and you certainly don't get the same washed out colors as in the way its been done to date.
The print modes I have done so far allow for various print speeds, the faster you print the harder it is (when creating the profile) to balance the white and color volumes of ink and because your white ink level is so critical getting the right pre treatment is also more important for single pass than multiple passes. But if you print slower then it becomes less of an issue.

But the best print I have ever seen on a black shirt was one created with the slowest mode single pass, it would be slower than two passes (by quite a bit), but the quality was truly outstanding, the definition was incredible.

There is also other speed factors which relate to the way software microweaving works on the different machines, which I am not going to go into.

I think there are definitely pros and cons to single pass and two pass, two pass is more forgiving in terms of pre treatment and you can over ink on the white and get away with it a bit more than single pass.
But single pass reduces trapping issues, multiple print pass alignment and print feed issues between passes.

Its not for me (or the manufactures) to decide which is best (although we can have an opinion), but ultimately it will be the market (the actual end users) and its still way to early to even guess what the market will decide on.

But it does offer a real alternative to the multiple pass printing on an Epson that can be used for any design.

Best regards

-David

David,
Thanks for the detailed explanation, this is what I was trying to explain to Marc with his question! As I said he is best speaking with you on this and deflected him that way Regarding brother i said same principle, I understand they have an offset head but essentially its the same concept outside splitting the channels in the Epson.. These were exactly my sentiments in my post as the end user knows what's best for them. It was just my opinion based on evaluations that its very hard to beat/ substitute the conventional two pass print with its jell time- when your after the highest quality brightest prints possible. Best Regards.

I see the in-line printing has been the biggest breakthrough at this years FESPA. Seems it has stolen the show.

Nice to see a company investing so much in research and development to produce the latest cutting edge technology.

Glad I'm in Club Resolute. Can't wait to see what's next.

This is the first time i saw Resolute in line printing and i was impressed the 'classic' printing with a solid white underbase in the low humidity was also good.

The humidity was very low, it read 14 at one point on Thursday afternoon. No issues though apart from a sore throat LOL.

Glad you liked it & even more pleased you witnessed the R-Jet was the only in-line printer at Fespa running textile ink with one print head
