To print on these items and more, the best product to use is called an IRC, or an "Inkjet Recep- tive Coating." The IRC is rolled on the sub- strate with a brush, air dried, then a second coating is applied. When printing on hard substrates, you want to reduce the amount of ink your printer uses due to the ink sitting on the surface and not absorbing into the material. Afterward, for more protection, you may also want to add a clear protective coating. As already mentioned, D2 printing on 100 percent cotton is always ideal. But, D2 equipment is moving beyond its original limitations. Improved ink and the pretreat- ments available are opening up the possi- bilities of what digital equipment can do. With extensive testing, finding the right combination is the key to your D2 print- ing success. PW Jerid Hill graduated from the Art In- stitute of Pittsburgh in 1993 for graphics and design. He entered the custom ap- parel and T-shirt industry in 1998 where he founded his own Printing and Design Company. Throughout the years, Jerid has written articles, blog and forum postings, created informative videos and taken the time to speak to many direct-to-garment users to assist in moving the industry forward. Introduced to direct-to- garment technology as early as 2004, Jerid sold off his business and took a position as sales manager with Belquette Inc. Hill has been a thought leader in the DTG industry pursuing new technologies for better direct-to-garment quality and output. His advice is well sought after in industry publications. In 2018, BelQuette merged with the ColDesi group of companies in Tampa and Jerid now serves at DTG Product Manager for ColDesi Inc. yield a smoother, more accurate color print, and it will also increase your durability in the wash. Often, a simple misting of light garment pretreatment and a quick 10-sec- ond press will achieve amazing results. But always check with the manufacturer, be- cause not all D2 inks can be printed on pre- treatment when not using white ink. Now, let's try to break down the confusion behind the "other" types of pretreatments. Not all pretreatments are created equal, so I'll attempt to explain the commonalities I've seen among the latest formulations. Dark garment pretreat: Most standard dark garment pretreatment can be used to print 100 percent cotton, 50/50 blends, and some tri-blends and natural fibers. Light garment pretreat: Typically used when not printing white ink on 100 per- cent cotton, blends, and 100 percent poly- ester. Polyester pretreat: Polyester pretreat was mainly used for printing on 100 percent polyester without white ink. Some of the latest dark garment pretreatment can be used on 100 percent dark polyester gar- ments. But, there's still quite a bit of a workaround involved, which reduces your productivity. Recent developments give you the option of printing on 100 percent dark polyester while using white ink without the slow- down in productivity. These new devel- opments are worth exploring, but an ink change may be needed for better results. This is always an area of concern since ink is the "lifeblood" of the printer. If the ink performs well, your printer will per- Pretreatment is designed with the substrate's fabric compo - sition in mind. Currently on the market, there is pre- treatment formulated for: • Dark garments • Light garments • Polyester • Hard goods
