ERIC - Effective Residual Ink Concentration Value

Posted on Nov 28, 2023 by HunterLab

ERIC stands for Effective Residual Ink Concentration and is a control parameter used to quantify the amount of residual ink left in recycled or de-inked pulp (DIP) and paper before and after de-inking and/or bleaching processes. Other parameters measured are brightness and dirt content.

Color Consistency in Art Papers Helps Paper Manufacturers Meet the Needs of Printmakers

While visiting a friend’s home, I noticed an enormous, beautiful painting hanging above the fireplace. Up close, I could see what looked like real paint clinging to the surface of the paper and assumed that I was looking at the original work of art. But when I asked my friend who painted the piece, she responded, “Oh, that’s actually a print! The artist was selling three of them just like it.”

Even if you can’t afford a $179 million Picasso, you can still get an excellent copy of that same painting for as little as a few hundred dollars, often much less.1. Yet not all art prints are worth hanging on your walls. The quality of the print paper has a huge impact on the appearance of the final piece; the color, opacity, and texture of the paper all affect how the inks and paints will appear once printed onto the final product. Color measurement tools can be used by paper manufacturers to ensure that each blank sheet of paper will allow printmakers to produce their ideal images.
