I am doing my first order with heather grey shirts that will have designs on both sides. I am getting mixed answers on pre treating grey-whether to do or not to do and when I pre treat shirts that are two sided do you pre treat both sides at the same time? I am thinking that will be too much pre treat if I do both together.
Thanks.
With that shirt color, it is important to know what the graphic you are printing. If the lightest color in the graphic is darker than the color of the shirt, then you don't need white ink. If you use white ink, you need pretreatment. No white ink, no pretreatment (as long as it is 100% cotton).
As Mark indicated, if you are printing white ink on the heather shirt you must use pretreatment. You might want to consider using FastBright Pretreatment instead of regular white pretreatment. FastBright is meant for white ink on light colored garments.
I have never heard of that pre treatment before. When I bought the machine I was told only pre treat dark shirts and wasn't told about options. I actually wasn't told about pre treatment until after I bought the machine. Is the application process the same? I am a little concerned being new to this that this process can be lengthy and be tough to compete with screen printers.
You have to apply pretreatment to any garment that you print white ink on. The application process is the same for the regular white pretreatment or for FastBright pretreatment. The FastBright pretreatment is designed to be used when printing white ink on light colored garments only. The spraying and heat pressing after is exactly the same method as with standard white pretreatment. You could spray by hand using a Wagner Control Spray power sprayer or you could use an automatic pretreater such as our SpeedTreater.

Harry, just a curious question...
Why use a different pretreatment on lights? Does it help with staining? Thanks.
FastBright Pretreatment will have less of a "stain" on light colored garments. It also will not yellow when exposed to sunlight. It is also half the price of the standard white pretreatment.
We have one large customer printing on six Blazer Pro Printers on light colored goods only who only uses FastBright Pretreatment when printing white ink.
Sean, The original type 1 pretreatment, was definately UV sensitive. Anything but pure black you had to treat the whole shirt and still had issues. The concentrate that Anajet has now is the type 2 formula with no UV sensitivity. I do a lot of sports grey and medium shirts with white layer and you can dilute a little more that 50/50.

The latest current version of standard white pretreatment from DuPont is UV resistant so you should haveno yellowing problems in sunlight. The DuPont white pretreatment is the one used and sold by pretty much all Epson based digital garment printers such as Anajet, Veloci-Jet, T-Jet, DTG, I-Dot among others.
