After printing the Perforated window film, the result might look, in first instance, disordered. This is caused by the fact that ink is also sprayed into the holes of the film. The ink comes onto the backing layer that due to its physical conditions does not spread the ink well. After removing the backing this phenomenon will disappear.

Brightly coloured inks (e.g., reds, yellows, oranges, and bright greens and blues) provide the best results. Avoid using dark colours (dark purple, navy, brown, black) for background colours. This is because with bright colours the eye tends to focus on the graphics, whereas dark colours allow the eyr to see through the graphics.

During screen printing, use more viscous ink and apply less ink than normal. Use lighter squeegee pressure than normal to prevent flooding of the holes with ink.
