How can ink mileage be increased on a press?
Oct 14, 2019

The amount of pigment in the ink will have the greatest effect on ink mileage. Pigment is the most expensive ingredient in ink; typically, less expensive inks with less pigment will have poorer mileage. Paper coatings keep more of the ink on the surface and tend to require less ink. Any condition on the press, including ink/water balance and printing pressures that cause the press operator to run a heavier ink film, will increase ink consumption. Theoretically, the best lithographic printing occurs with just enough fountain solution to keep the plate from scrumming and just enough ink to print the required solid ink density. GCR (Gray Component Replacement) can also reduce ink consumption of process colors by making the black separation heavier and reducing the amount of ink used by the CMY separations to create grays.

U.S. International Trade Commission Approves Tariffs Targeting Aluminum Lithographic Printing Plates from China and Japan

On October 22, 2024, the U.S. International Trade Commission (USITC) determined that a U.S. industry is materially injured by imports of aluminum lithographic printing plates from China and Japan. The U.S. Department of Commerce determined that the printing plates are being sold at less than fair value and subsidized by the government of the People’s Republic of China.

PRINTING United Alliance Opposes New Tariffs on Aluminum Lithographic Printing Plates

On September 13, PRINTING United Alliance, in partnership with the News/Media Alliance, sent a cross-industry coalition letter to the International Trade Commission (ITC) urging the commissioners to reject antidumping (AD) and countervailing duties (CVD) on imports of aluminum lithographic printing plates from China and Japan. The duties were preliminarily imposed earlier this year at an excessive rate of 200% (China) and 87% (Japan). Because there is no U.S. supplier of the highly technical lithographic aluminum sheet product that is necessary to make the printing plates, they must be imported.
