Will the PH value of fountain solution be affected by the PH value of paper?
Can the pH of the fountain solution be affected by the pH of the paper? Yes, the pH of the paper can indeed influence the pH of the fountain solution. Fountain solutions are typically slightly acidic, with a pH range usually between 4.5 and 6.5. When the paper has a high pH—meaning it's more alkaline—the alkaline components present in the paper can dissolve into the fountain solution during the printing process. This dissolution disrupts the original acidity of the fountain solution, leading to neutralization. As a result, part of the acid in the solution is neutralized, which raises the overall pH of the fountain solution. This change in pH can have several negative effects. It reduces the surface tension of the solution, which can speed up ink emulsification. This may cause the ink to separate more slowly, affecting its normal transfer onto the paper. Additionally, the altered pH can lead to poor ink adhesion and uneven print quality. If the paper has a low pH—making it more acidic—it can lower the pH of the fountain solution, increasing its acidity. This can interfere with ink drying, causing it to take longer to set. It may also reduce the lifespan of the printing plate and, in some cases, lead to issues like page drop or loss of image detail, which can significantly impact the final print quality. In general, most paper has a neutral pH of around 7.0. However, depending on the type of paper and its production process, this value can vary. It's important for printers to monitor both the paper and fountain solution pH to ensure optimal printing performance and consistent results.
