New Product Cotton Printer ?

I'd like to print natural fabrics like cotton canvas / twill for laptop and phone sleeves and i'd like to know what do you use for this kind of material?

I have an eco-solvent printer but it prints only coated materials (the new fancy solvent printable canvas is not available in Europe yet)

I tried hp latex it works ok but dark colors are not dark enough, rich black comes out as super dark grey even with 80c 80m 80y 100k

DTG printer works best with precoating but it prints only 1 sqft or so

Do I have other options like uv printers or something else under 20k ?
