This document summarizes the multi-step process for manufacturing offset printing plates from aluminum coils. Key steps include cleaning and degreasing coils, graining to increase surface area, anodizing to add abrasion and corrosion resistance, applying post-treatments and coatings tuned for specific imaging technologies, converting coils into sheets, and packaging finished plates with identifiers. Quality control throughout monitors factors like tank concentrations and coating thickness to produce plates that meet requirements for high quality imaging and printing.
