Experiment with varying amounts of white. Using a smaller amount of white coating can create a lighter and gentler sensation. If you decrease the white to 75-80% and still achieve a beautiful bright white, this can be an effective method to achieve the desired soft outcome. B ut you have to make sure that reducing the amount does not impact the powder's adhesion to the fabric or the brightness of the colors, especially on dark or colored garments, And the other concern when you decrease the white is, if you work with lower-quality colored fabrics, there is a possibility of dye migration occurring during the transfer process. This is when the colors from the garment blend with the white base, leading to unintended color changes.
2. Using softer and lighter fabrics usually leads to a softer outcome.
3. The density of the adhesive powder coating significantly affects the softness of the print. Ensure of having good quality of pure adhesive power.
It is advisable to test the new settings on a garment by washing it to ensure the color's vibrancy and assess the ink bonding effectiveness.
And remember It is a lot of trial and error until you get it right!
