Offset Printing - Sheet-Fed
The DryStar infrared or ultraviolet dryer of a Heidelberg Speedmaster press produces heat in the delivery to aid drying. The water in the dryer cools the sheet guide plates near the heating elements. Failure to maintain the proper flow and pressure of the cooling water can lead to serious damage. To protect the dryer, make sure that pressure readings are as follows: SM52: 0.8 to 1.0 bar SM74: 1.0 to 1.5 bar CD74: 0.6 to 0.8 bar SM/CD102 with DryStar 2000: 1.0 to 1.5 bar SM/CD102 with DryStar 3000: 0.6 to 0.7 bar XL105 with DryStar 3000: 0.5 to 0.6 bar As with all limits and specifications, always consult
When running polyester plates on a Printmaster GTO 52 with a direct continuous dampening unit, do not thin the ink with print oil or other additives. Keep the water pan spotless so that no grease gets onto the plate. The dampening system’s pH value should be about 5. (Important: do not add alcohol.) To avoid overstretching the plate during mounting, tighten the tensioning nuts only by hand. Compression between the blanket and the plate cylinders must not exceed .1 mm. Before production, polyester plates must be treated with the sponge-on etching solution recommended by the manufacturer. If printing is interrupted, more etching solution should be
Using enhanced GCR (gray component replacement), it’s possible to use just three different screen angles in seven-color printing without risking color shifts. Black, as the dominant color, is assigned to 45°. The six chromatic colors, cyan, blue, magenta, red, yellow, and green, are alternately assigned to 165° and 105°. Then, each hue can be generated using only three colors: black, which provides the gray component; and two neighboring colors. For example, all printable hues between red and yellow can be created using black and these two process colors. A maximum of 10% of a complementary color can be added to darken the color without causing
Maintaining proper airflow inside the cabinets of Heidelberg press peripherals such as AirStar, DryStar, and CombiStar is critical to their operation. Too much or too little air flow can lead to improperly cooled components and premature equipment failure. Essential for maintaining correct air flow are proper exhaust ventilation; regular maintenance of filters and air vents; and cleanliness inside and around the cabinet. The pre-installation manual for your press gives detailed ventilation information that’s customized for your specific configuration, including air flow rates, exhaust duct sizes, and requirements for a helper fan. Detailed instructions on filter and cabinet maintenance can be found in the device’s

AROUND EACH turn of every corner stood a reminder of the greatness that is Strine Printing. Dave Kornbau, the company’s vice president of operations, was a popular man while providing a walking tour in early August. His cell phone rang every few minutes. Co-workers handed him press samples here and there. Quick questions received lightning-fast answers. It was like watching an episode of “The West Wing,” the White House drama, only without the constant scowls. Kornbau paused and gestured toward bulletin board-type displays that adorned the hallway walls. Rich colors and textures were everywhere. Sparkling ceiling mobiles danced in the cool air, their diecut
