Epson 3880 (which is the base of all TexJets expect Shortee model - made of P600 if I remember correctly) original ink (that you use to print photos on paper) is water based and don't clog at all. You don't need to wet cap the printhead or do all this annoying maintenace. Just push the cleaning button and there you are. You can leave the printer idle for days or months. Even if your printhead is clogged I think there is a much bigger chance to restore it than when using DTG inks.
DTG inks (CMYK) are also water-based but it's totally different chemistry and physics. By more dense I mean more solid. They're made this way because everyone would like to achieve great prints and great washability on shirts etc. White ink is made of TiO2 which makes it the hardest ink to maintain.
We are all jeting the solid, dense inks which tends to clog with modified desktop printers. I mean that's the way how it works on almost all DTG printers on the market. Expectation is: Epson F2000/F2100 (which are also very problematic from what I see), Kornit, Aeoon (but the last two are also not-trouble free and are rather industrial machines than printer for a small shop or hobbyst).
I dream about the day when you can just turn printer on, print some tees, then simply turn it off and go home without a fear
