AQUATONE® Inks have lower viscosity than PERMASET fabric printing inks, more similar to that of shampoo, so a finer screen mesh will typically be required. As with most water-based inks, the image area should be flooded between prints to prevent the ink from drying in.
PERMAPRINT Premium Inks have relatively high solids and proportionally little free water. In common with HSA textile inks, they are more prone to drying in on the screen.
When printing with water-based inks, it is good practice to flood the image area between print strokes, immediately after lifting the screen. Small deposits or thin films of ink retained in fine mesh are prone to dry in quickly.
By flooding straight away, fresh ink will wet out these deposits and prevent drying-in.
- Ensure screen is hydrated before starting the print run.
- Ensure a nice even flood between prints, around 1-2 mm thick
- Ensure humidity is greater than 40-50% RH in the print room
- Sometimes a slightly lower mesh count can help. Maybe drop to a 77 T (195 tpi), although this should be balanced with the propensity of low viscosity ink to run through a coarser mesh.
