Leo is Recognized as An APTEC CTV Certified Printing Company

202608121603
In July 2026, we earned Colour Tone Value (CTV) Certification from the Advanced Printing Technology Centre (APTEC), a subsidiary of the Hong Kong Printers Association. CTV is an advanced print color control methodology that enables more consistent color reproduction, improved tonal control, and enhanced print performance across print and packaging applications. By monitoring both color and tonal values throughout the production process, it helps achieve more consistent and predictable print results.

This certification delivers tangible benefits for our clients:
  • More consistent brand colors across products, packaging formats and production locations.
  • Great production reliability with reduced variation and quality risks.
  • Stronger shelf impact through enhanced image quality and color reproduction.
CTV is the first printing-related standard established within the Guangdong-Hong Kong-Macao Greater Bay Area and an ISO-recognized standard. Earning this certification reflects our ongoing commitment to international standards, technical excellence, and continuous improvement. As we continue to expand our printing and packaging capabilities, we remain committed to delivering high-quality and reliable solutions that help our clients achieve consistent results and maintain strong, recognizable brands.
