    00:10 Here at Wallkill, we have two rotary presses. 00:13 Each prints something called a signature, 00:15 which is virtually the same as a 32-page brochure. 00:18 The press can print up to 94,000 signatures per hour. 00:23 If these were stacked on top of each other, 00:25 they would reach the height of a 30-story building every hour! 00:31 The process begins with a 3,000- to 4,000-pound roll of paper. 00:36 It’s loaded along the press, rolled into place, 00:39 trimmed, and lined with double-sided tape. 00:43 Before the previous roll is finished, the new roll is loaded onto the splicer. 00:50 By means of double-sided tape, 00:52 this roll is attached to the expiring roll. 00:58 Next, the paper advances to the four print units, 01:01 which apply ink on both sides of the paper at the same time. 01:05 The presses use a technique called offset printing. 01:09 This process uses printing plates designed to allow water 01:14 to repel ink from the nonimage areas 01:17 and attract ink to the image areas. 01:20 The plate then transfers the ink to a rubber blanket, 01:24 which then transfers the ink to the paper. 01:31 Four colors of ink are used to create the images. 01:34 They are black, cyan, magenta, and yellow. 01:39 The ink on the paper is applied in tiny dots. 01:42 By using this technique, a wide range of colors can be achieved. 01:50 Now the paper goes through the dryer, 01:52 which maintains a temperature of around 400 degrees Fahrenheit 01:55 (200°C). 01:57 Solvents from the ink are evaporated inside the dryer. 02:02 Next, in order to set the ink so that it will not smear, 02:05 the paper travels through a series of rollers filled with chilled water. 02:09 Now that the ink is dry, 02:12 the paper is folded and cut. 02:16 Finally, the conveyer brings the cut signatures 02:19 out of the press, and they are checked for quality. 02:24 They are then processed and distributed to the congregations.
