Harper Corporation of America shows QD system

Harper Corporation of America shows QD system

Global anilox roll supplier Harper Corporation of America is displaying its latest technology and products at Labelexpo Americas 2018 and discussing how available programs, services, and anilox technology can enhance print repeatability and improve profitability.

One of the systems on display will be Harper’s award-winning patented QD ink proofing and flatbed printing system which uses flexographic and gravure processes. 

This system has become a color-matching proofer used by many leading ink manufacturers and is able to be configured at four different speed units. The maximum travel speed is 150 ft/min (45 meter/min), and travel distance can be adjusted anywhere from 12 to 33 inches in one-inch increments. It is also available in either a 2.75-inch or 5-inch proofer width.

The company will be showing its newest addition, the Harper Performance Wash, which is a fast-acting, low foam, highly alkaline-based anilox roll cleaner.

The Performance Wash is effective at removing water-based, UV, and solvent inks and can penetrate through multiple layers of ink. In addition, it is ready to use at room temperature or can be heated up to 100 degrees F. 

This cleaning product can be used in automatic roll cleaning machines with rinse cycles or ultrasonic tanks. It is a concentrated solution, but it can be easily diluted with tap water to meet the needs of different cleaning methods, types of ink, and roll conditions.
