You certainly can but a few things to note

-For the first few prints you might have maintenance solution dripping from the white heads. If it drips into a design area it might spoil the shirt. Goes away after a while
-If you dont plan on using white heads longer than 2 weeks then you'll need to run another white tube flush with the maintenance solution. I would recommend you remove the whiteheads completely and store them until you need it.
-Learn to love white ink! Honestly it's super easy with the Brother machines and ink sets (compared to other brands). As long as you can print a dozen or so prints a day it should be fine.

Thank you for that advice...I bet that's my problem too!

What brand 100% cotton did you switch to?

I was using Gildan Ultra Cotton (100% cotton) and the prints were super dull. My tech (from a Brother distributor, not Brother itself) said they never use Gildan because of the dull print results. Now I'm in search of a better 100% cotton brand to try.

I have attached a picture of white ink printed on a black tee using the default 600 dpi settings on DF. Personally, it is not comparable with a pure white print via screen printing or vinyl.

So it would be great to know if it's also the same for other users out there? I could increase the underbase (highlight in PDIP) to get better white, but I read that in 600 dpi it's not recommend?

Any thoughts on the white print, if it's something you will put out to customers?
Naka,

I'm pretty sure mask is the underbase and highlight increases overall white ink. judging by the picture your highlight is too high and think is pooling on top. Try the same design on 6/5 and let me know how it looks.

Also, more pretreat is always good. What ratio are you mixing your pretreat and water?

Re: White Ink - Newbie Thread

How rough are you guys when cleaning the inside?

There's been 2 previous training sessions with other staff done by amazing Brother reps.

But I recently had a horrible Brother rep come in and quite wonkily trained my staff on maintenance. Acting cool while leaning on the inks, not using gloves and getting ink all over himself while handling the wiper cleaners...got a bit of blue into the white capping station. Pulling on the sensor strip a little too strong. I'm not sure if I'm too anal about this stuff.

Re: White Ink - Newbie Thread

Hello - quick question. Digital Factory Software - how do I turn on the grid in the preview? Need the grid to help with alignment.

We get that sometimes but a little bit less. You can PULL it away but never try to push or rub it into the rubber membrane. You dont want dried bits inside.

Re: White Ink - Newbie Thread

Just looked at the insertion nozzle of the white cartridge.

Is this normal?

I agree - short term pain, long term gain!
- Try hover the heatpress 1 cm above the print for around 20 seconds. This will set the colour layer and will reduce it sticking to the teflon sheet
- 50% less bright is pretty crazy. Try the hover press option first it should help this too. You should always expect some loss of vibrancy after heat pressing as you are removing moisture from the ink

SIDE BUT IMPORTANT OBSERVATION:

I've been using this machine for low to medium level printing since mid-february. I've been printing a lot of CMYK and I still don't have to change any of them.

My whites on the other hand - installed early May, now 3 cartridges are empty! Daily Cleaning has been really draining the whites. AARRGGGHHH!!! I'm wishing I never upgraded right now...but I'm sure I'll be eating my words once my main business starts in August.
How come you aren't using your heatpress to cure after printing? Seems like way too much effort to use a hand dryer and it wouldn't be ideal either. Use the heatpress to cure pretreatment and your prints after printing. I'll be surprised if your prints wash well with a hand dryer. Do let me know I'm curiour .

3 White carts sounds like a crazy amount for just a month, even with Daily white cleans. Have you changed the setting so it is 50-80% for daily white cleans?

Short term pain, long term gain. You won't regret white ink print and its impact for your business once you get rolling.

Re: White Ink - Newbie Thread

Hey Sunny...I think it's normal. Most of my cmyk prints are around 1cc and even less when printing on dark.
As reference, my current set of CMYK is still going strong though my whites are already on the 3rd set. I'm on the GT 381.
