Discuss the various aspects of direct to garment printing. DTG printers include Brother, T-Jet, Flexi-Jet, DTG Kiosk, Kornit, Mimaki, Tex-Jet and others! Discuss and learn about this up and coming printing technology.
Recently, we purchased one of Equipment Zone’s Automatic Pre-Treatment Systems. Based on our experience, we would recommend this unit to anyone who wants to accomplish the following:
An immediate reduction in labor cost. What generally required two people, one person to run the press and one to handle the pre-treating; this machine has reduced our production work flow to one person.
The machine gives you the ability to adjust timing and area of spray. The benefit is you can now control the area that you are pre-treating along with the volume of pre-treat liquid used on a garment. Bottom line, this saves you money and controls consistency better than pre-treating by hand.
Finally the design allows for solution recovery. Any excess solution falls in run off bottles on each side of the machine allowing you to capture and recover any solution and use it again. This is a valuable feature that has resulted in very little waste.
Reducing cost and improving efficiency are definite benefits of Equipment Zone’s new Pre-Treat machine
you do still need to heat press after the machine sprays the pretreat.
I will expand on this.
The spraying aspect is only one part of the sequence required to get results that are consistent.
You will still need to pre-press with distilled water before you put it into the spray unit and then you will need to knock down the excess droplets and then press until most of the moisture is evacuated.
The process before and after are just as important as a controlled spray.
Ironically the new Dupont pretreat is much less ficle as the old formula and is much more forgiving with less hand.
So decent results can be done by hand, but its' still quite sticky so the ecloser will keep your erea clean.

So if we use an autopretreatment machien we still need to spray distlled water on the shirt before putting it into the machine? I thought the whole point of these auto pretreatment machines was to eliminate that step because it was a more consistent spray.

I can only speak to how our SpeedTreater Automatic Pretreatment System works. Our users of the SpeedTreater do not prepress before or sponge after. They put the shirt on the machine, the machine sprays the shirt, and our users just press the shirt for a few seconds before printing it.
Mark is correct in that having the spray enclosed keeps your area clean. One of the advantages of the SpeedTreater is that you can use it the same area as your printer instead of having to go to a separate room to pretreat by hand.
Thanks Harry, I was going to comment on this as I remembered reading your post in another thread stating this, but I couldnt remember which one it was so I waited for you I thought you had said it didnt require any other step except pressing after pretreatment.

Every users expectations of what is good can vary.
This is my experience of what achieves the best result.
If you did a side by side comparison of one just sprayed vs one with pre and post treatment it would become apparent.

Our experience has been different than yours. The SpeedTreater does not require spraying with distilled water. Our machine consists of an "End-to-End" process. Mount the shirt and treat with appropriate pre-treat solution. Take it out and print on it. No additional steps are required.
Do these automatic pretreatment machine result in lower shirt color alterations? when you spray too much the pretreated area becomes darker. Can you change the spray area of the treatment?
The SpeedTreater allows you to control the length of the spray. What makes it unique is that the length can be set on the PLC both for top and bottom. For example, if you wanted a 4 inch high band in the center of the garment you can program it in that way.
Because it is an automated consistent spray you should have significantly less chance of darkening the pretreat area.
