UV Letterpress Inks and Reference Formulas
Since letterpress printing is not as good as offset printing and flexographic printing, and the printing speed is not as good as offset printing and flexographic printing, it is being used less and less, and therefore the production of letterpress inks is also decreasing.
For UV letterpress ink, please refer to “3.5UV Flexographic Ink”.
