Ink does not alkali will have an impact on blot color.
For printed paper PH = 7, neutral paper is the best, usually ink made out of inorganic pigment is acid, and alkaline is poor relatively, organic pigments acid and alkaline is good, especially blue, dark blue ink will fade in case of alkali, yellow changes to reddish with alkali case. Stamping hot stamping foil and printed gold encounter alkaline substances will be into ancient yellow, no gloss. Paper is often weak alkaline, in the printing post-production encountered adhesives contain alkaline, we must take into account the ink alkali resistance. If the packaging printing products are packaging alkaline substances such as soap, toilet soap, washing powder and other substances, we need consider saponification performance.
