Common challenges faced during calamari color inkation include color variation and uneven distribution. Color variation often arises due to inconsistencies in ink concentration or substrate preparation. To address this, ensure precise ink measurement and thorough substrate cleaning prior to ink application. Uneven distribution can be attributed to faulty equipment or improper ink flow. Inspect ink delivery systems regularly and adjust ink viscosity as needed to achieve optimal distribution.

To minimize color fading and improve ink adhesion, consider incorporating UV stabilizers into the ink formulation. These stabilizers protect against color degradation caused by sunlight exposure. Additionally, enhance ink adhesion by pre-treating the substrate with an appropriate primer or adhesive promoter. This step helps create a strong bond between the ink and substrate, resulting in increased durability and resistance to wear.
