Problem: Ink color changes, shifts, or bleeds after application

 

Solutions:

Ink Contains Pigments That Are pH-Alkaline, pH-Sensitive, Solvent Or Hydrophilic-Sensitive

• Use alkali-resistant, permanent pigments.
• Avoid the following alkali-based pigments: rhodamines, reflex/alkali blues, methyl violets, and barium red lake C (warm red); laked and fluorescent pigments.
• All aqueous coatings are alkaline (pH 8.0 to 9.0). This causes sensitive inks to change shade or bleed as the inks oxidize.

Inks Are Formulated With Salt-Containing Pigments

• Exercise care in using these pigments, including lithol rubines, 2B-reds, bon reds, and lithols. Consult Nicoat about the best formulation to use with these inks.

Dye Inks Are Used

• Avoid dye inks. Consult ink manufacturer.
