DTG Pretreatment is needed to print white ink onto shirts when it comes to dtg printing. It also gives you more vibrant prints on light color shirts if you use pretreatment made for light color shirts.
It acts like a primer between the shirt and the ink. If you printed ink directly onto a dark shirt you would not be able to see the image at its full potential because the inks would be absorbed into the shirt. I guess it's similar to hair dye. If you dyed your hair light brown but your hair is already black it would most likely not change the color of your hair unless you bleach your hair and then apply the dye. Now you will have the light brown you were looking for. Was that a bad example? Half of it lol. Well, hopefully, you understand what I am saying.
Anyways, It also reacts with the white ink. It makes it kind of tacky making it stick and quickly cure. This happens so that when you go to print your color ink on top it will stick instead of being all runny. You have probably seen this happen if you print with too much ink.
Pretreatment for white t-shirts in DTG printing is not always necessary but can still be beneficial. Pretreatment primarily serves to improve ink absorption, adhesion, and durability when printing on dark-colored garments, as it helps the white under base layer bond better with the fabric.
However, when printing on white or light-colored t-shirts, an under base layer is usually not required, and the CMYK inks can be directly applied to the fabric. In this case, pretreatment might not be as crucial.
That being said, some printers and ink manufacturers recommend pretreating white t-shirts to achieve better print quality, color vibrancy, and washability. If you choose to pretreat white t-shirts, follow the same process as you would for dark garments, but use a pretreatment solution specifically designed for light-colored fabrics. Always test your pretreatment process on a sample garment to ensure desired results before proceeding with a full production run.
We downloaded the MSDS From ImageArmor Pretreat and it basically said it is 68-98 % water. and 1-20% calcium nitrates, which are basically Salt. Salt does have the potential to be a skin irritant. It also has a 1-12% vinyl chloride copolymer, which is basically glue. To find out more about DTG Printing Pretreatment click the link.
Below is some of the information that is said on the Image Armor Pretreat MSDS Sheet. I suppose that all the pretreatments are made basically the same. Maybe 1 uses a different type of salt or glue or a different brand of chemical but the majority of it is water. Probably 95% Purified water and 2 and 3 % salt and glue.

We use a DTG Pretreatment Machine. In the beginning, we use to use a Wagner spray bottle but it got really messy. The sprays are also inconsistent and you waste a lot of pretreatment. That is why we are happy that we upgraded.
Direct-to-garment (DTG) and direct-to-film (DTF) printing are two popular methods in the world of apparel and textile printing. Both methods use advanced printing technology to produce high-quality, vibrant prints on a variety of materials. In this guide, we'll take a closer look at DTG pretreatment and DTF printing, discussing their unique features, benefits, and applications.
DTG printing involves applying ink directly onto the garment using specialized inkjet printers. To achieve the best results, it's essential to pretreat the fabric before printing. Pretreatment is a crucial step that helps to improve the print quality, durability, and vibrancy of the final product.
Why is pretreatment necessary?
Direct-to-film (DTF) printing is a newer technology in the textile industry, offering an alternative to traditional DTG printing. Instead of printing directly onto the garment, DTF printing involves printing the design onto a special film, which is then heat-transferred onto the fabric.
Benefits of DTF Printing:
DTF Printing Process:
Both DTG pretreatment and DTF printing have their unique advantages and applications. While DTG remains popular for its high-quality prints and suitability for small batches, DTF printing offers versatility and cost-effectiveness, making it an attractive option for businesses looking to expand their product offerings and reach new markets.
