The United States Ai Yaixin New 500 Series Chinese Showing Spectroscopic Density Gauges adopts advanced spectrum induction technology to provide a more accurate and more accurate portable spectroscopic density. Features The maximum feature of the 500 series is to measure four colors and special inks, but also have a variety of density, outlets and chrominance functions. It is very suitable for the printing industry and all kinds of printing industries, especially for the packaging industry. Each of the color measuring instruments produced by Ai Li Li have been strictly verified. In addition, the instrument will still automatically provide correction instructions to maintain its stability or different locations, resulting in a consistent reading. Applications 504 spectroscopic density meter The density reference can be measured quickly, reliably measured density levels, density (absolute or subtracted paper density). 508 spectrophotometer With all the features of 504, you can also measure the functionality of the outlet area and the increase in outlets. 518 spectrophotometer With complete measurement, including density, mesh, superposition, printing contrast, tone error, and grayscale. In addition, it also has a unique function-automatic selection function, which can automatically identify the field, outlets, and stack of fields being measured. You can display the reading without a conversion function. Type 518 is suitable for all types of four-color printing, including offset printing, cockroach, reel, magazine and newspaper printing, convenient for the first time to learn printing. 528 spectrophotometer In addition to all functions of 518, 528 more include chroma function, such as: L * a * b *, l * c * h0, etc., is a advanced instrument that combines spectrophotometer and density instrument, especially suitable for packaging and printing monitoring Color and spot color use. 530 spectroscopy 530 plus complete spectral function, including spectral curve diagram, spectral density data, etc. 530 combined with ink coloring system and color quality control software in the laboratory and quality inspection department.
