G7 methodologyThe G7 Method is a printing procedure used for visually accurate color reproduction by putting emphasis on matching grayscale colorimetric measurements between processes. G7 stands for grayscale plus seven colors: the subtractive colors typically used in printing (Cyan, Magenta, Yellow, and Black) and the additive colors (Red, Green, and Blue). The method uses a one-dimensional neutral print density curve (NPDC) to match neutral tonality between two G7 calibrated printing systemsCRPC3 press referenceThe relationship between CMYK input data and color measured on a printed sheet for a given set of printing conditions is defined as the characterization data. When a dataset isused as a reference, it is referred to as the characterized reference printing condition (CRPC). CRPC3 refers to Universal PremUncoated and the typical use is printing on matt uncoated type paper. CRPC6 press referenceThe relationship between CMYK input data and color measured on a printed sheet for a given set of printing conditions is defined as the characterization data. When a dataset isused as a reference, it is referred to as the characterized reference printing condition (CRPC). CRPC6 refers to Universal PremCoated and the typical use is large gamut (typically commercial) printing.E00 Delta E is a standard measurement created by the International Commission on Illumination that quantifies the difference between two colors. Delta E levels are the difference between the displayed color and the original color standard of the input content. Lower Delta E figures indicate greater accuracy, while high Delta E levels indicate a significant mismatch. Technical Definitions
