Color perception is subject to illusions and trickery, but color measurement devices don’t have the same limitations. In this process, laser burn the black layer (Lams layer) to form a raster image based on design file. Flexographic printing is significantly faster than digital, making large runs of labels more cost-effective to print on flexo presses. Laser printers use laser beams, electrical particles, heat, and a plastic particle called toner to create an image, whereas inkjet printers spray ink from cartridges directly onto the paper. Standard operating procedures (SOPs) provide a roadmap, help with issues, and make it much easier to train new employees. Flexographic Image Reproduction Specifications & Tolerances supports the methodical approach to process control, optimization, fingerprinting, characterization and process improvement as outlined in CGATS TR 012-2003 (Graphic Technology – Color Reproduction and Process Control for Packaging Printing).
