Selecting an inkjet plotter requires matching the print head technology and ink type to your specific needs. For CAD and architectural blueprints, thermal inkjet (TIJ) technology is preferred for sharp lines. For outdoor signage or textile printing, piezoelectric heads (like Epson or Ricoh) are superior due to their durability and compatibility with solvent, UV, or sublimation inks. Always verify the maximum printing width (e.g., 24, 36, or 72 inches) and DPI resolution (minimum 1200 DPI for high-quality graphics) to ensure it meets your output standards.
