Quality Issues - Pretreatment
The application of pretreatment to a garment is going to have the most significant effect to
your print quality. At first, the pretreatment process will be a learning curve for you to master.
Some get the hang of it on the first day and for some, it can take a while, as everyone’s level
of proficiency is different. When you purchase a printer, it comes with the industry standard
Wagner Power Sprayer, a hand held sprayer. Refer to the Pretreatment section of this user
manual (page 7-8) for the recommended guidelines on applying pretreatment.
If you do not apply the pretreat properly you are going to see a lot of different was it can affect
your print quality. The major mistakes made are not enough or an irregular and inconsistent
pattern, or both. Pretreatment needs to be sprayed in a consistent amount so it is evenly
spread across the garment. Not enough will give you a very dull print on dark garments, then
white will look grey and fuzzy. An inconsistent spray will leave the print looking splotchy with
areas that look ok and areas that look bad. If the pretreatment is spayed in an even coat the
print should look the same all the way across and down the garment.
When it is inconsistent you have more pretreat in some areas and less in others, this creates
a spotty, patchy look. Here are some common pretreatment mistakes:
1. Not Enough Pretreatment
Not applying enough pretreatment will cause a dull and fuzzy looking print for both your white
and color layers. If washed, the print will not hold up due to not enough pretreatment adhesing
the print to the garment. In this case, you will need to apply more pretreatment.
2. Pretreatment Hand-Sprayed In An Uneven Pattern.
This will cause a spotty print with areas of good and bad-looking prints. When pretreating by
hand, pretreatment should be sprayed at an even speed and distance to ensure the most
efficient and consistent print.
3. Too Much Pretreatment
Applying too much pretreatment will cause the garment to become too damp, bleeding into the
back side of the garment and causing the pretreatment to move down the garment when picked
up. Once dried, the shirt will appear very stiff and may even cause an ugly translucent square to
appear on your garment. A print on a shirt with too much pretreatment will appear good but in
the wash, the graphic will begin to peel or stick together.
4. Wrong Pretreatment Used
There is a difference in the pretreatment formulas for light, white, and dark cotton garments as
well as light and dark polyester garments. Using white or light pretreatment on a black or dark
garment will cause your white underbase to improperly print; resulting in an all-around dismal
print. The rule of thumb is that if your print requires the use of white ink...
