The original London Digital Plate Gauge was first introduced to the Flexographic Platemaking Market in 1982. Since then, hundreds of the "London Micrometers" have made their way into the marketplace. Quality and accuracy have been integral to London Digital products from the first gauges produced 20 years ago to the current models. While the company name may have changed, the goal of constant improvement is still very much a part of their business.
London Digital Micrometers are designed to measure Photopolymer & Rubber Plates, any type or thickness of substrate up to 1/2 inch (12.7 MM), Steel Rule Dies, and have many other measurement uses. All models have a base that is made with a scratch resistant acrylic material. London Digital Micrometers utilize the most accurate measuring heads on the market. The heads are set from the factory, measuring 1/10,000th of an inch but they also can be set to measure up to 5/100,000ths of an inch or fifty microns. In metric mode the heads can be set to 1/1000th of a millimeter. Either setting offers an unsurpassed level of measurement accuracy. London Digital Micrometers do not damage the plate surface. The measuring foot exerts 1.5N or less, which is the equivalent of 16.96 grams of force per square inch. Even the finest type or other isolated dots will not be crushed and accurate results will still be achieved. For this reason, plate manufacturers have been recommending London Digital products for over 15 years.
London Digital Micrometers use an absolute glass scale linear encoder so that when the client zeroes their Micrometer, the zero point will not change until the client changes it. This means that the micrometer can be used to measure the floor of the plate or the cap of the plate. The micrometer can be programmed for a specific height (for example, .067") and for a range of tolerances so that each measurement taken will either register a red light or green light on the head display. London Digital also offers a printer with standard footswitch which can be added to any model. This allows the client to record the measurement results on a permanent basis. The printer automatically records the time and date on the printout and all selected points on the plate. Activating the data button will produce and record information such as thickness variation per color or plate, average and mean measurement, and other statistics vital to quality assurance.
