When you printed the 100% cotton, the fibers took the ink, the 50/50. the poly does not and the cotton does. So I think the grey you see is the result of this. Maybe check your ink types, be sure you are using inks designed for polyester and cotton mix. Also I notices another post, a few corrections on that: Polyester shrinks really bad going through tunnel dryers and other final cure dryers However when regular laundry washing 50/50 shrinks less and 100% cotton always shrinks, unless your manufacture pre-shrinks the garment or you have your garment cut for estimated shrinkage in order to shrink after wash to the correct size. Anyway good luck, I hope you understand my advise on this as my factory manufactures T-Shirts all day long, so I have to know this for my customers that are printers.Well, I tried the 3G paper with 100% cotton and 50/50. On the cotton the colors looked great just like they were printed but the 50/50 the white turned almost grey. Any ideas what would cause this?
