In DTG printing, all inks are concentrated pigments, rather than diluted pigments. This means that all DTG printers will attempt to make up the missing information by spreading the ink, causing the fabric to have a lot of gaps with a visible white base. This is most evident on dark fabrics.
To prevent this, we advise avoiding pressure-sensitive brush tools. Watch our video on DTG Print Files & Transparency to see such brush tool in action and how it affects the end result.
