The resultant test pattern is characterized visually for mottle and porosity. After one minute remove the ink by first scraping off most of it with a straight edge, then wiping away the remainder carefully with a clean paper towel. Test Procedure: Spread the ink on the paper to be tested using a spatula or drawdown applicator. Examples of test patterns obtained using the two inks, demonstrating their specialized nature are as follows: This document contains instructions for printing a test page, a Printer Status Report, a Print Quality Diagnostic page, a Wireless Network Test page, a Network Configuration Page, a Printer Information Page, and a Web Services Report. Uncoated papers, being low in holdout, require a low penetration ink to avoid excessively strong color that would overwhelm any mottle or holdout distinctions. Coated papers, being relatively high in holdout, require a high penetration ink to obtain a sufficiently strong color and mottle pattern. Inks of both high and low penetrations are required because the penetration quality of the ink must be appropriate to the holdout of the paper surface being tested. These testing inks provide a simple and rapid way of monitoring batch-to-batch variations in paper structure and porosity. For Evaluating Mottle, Holdout and Porosity of Coated and Uncoated Papers
