We have an SP20 and an 18 x 24″ magnetic base. We recently ran a job that required a full flood (with only minor knockouts), flood size 15.5 x 17.5″ We were attempting to minimize the saltiness of the print, so we upped the packing and the ink. Does anyone have guidelines to follow in regards to how much is too much to ask of a press? What do we risk by running such a large flood with heavy packing? Can we throw the bearings off? Damage the underrails? We love to do unusual and difficult jobs, but we want to keep our equipment in top condition. Any advice or information is much appreciated!
