How to Avoid Color Difference in PVC cards Customization? 

Color difference is a common problem in
PVC card customization . It can be avoided through three steps: standardizing design drafts, selecting professional manufacturers, and strictly confirming samples.  with 16 years of printing experience and standards...

The standardized production process controls color difference to △E≤3 (difficult to distinguish with the human eye), far exceeding the industry average.

I. Three Major Causes of Color Difference

: Design Issues: Using RGB mode (screen display) instead of the printing standard CMYK, or a resolution <300dpi leading to blurry patterns;
Production Process: Inconsistent ink and printing pressure between different batches, or using different printing presses (e.g., Heidelberg vs. domestic machines);
Material Differences: Variations in whiteness and thickness of PVC substrates, resulting in uneven shades of dark colors (dark blue, black). II. Core Methods to Avoid Color Difference: 1. Standardize Design Format and Mode: Provide CDR/AI vector files, convert color mode to CMYK, and specify Pantone color codes (e.g., PMS 286C); Avoid Gradients and Small Text: Large-area gradients are prone to color differences due to uneven ink layering; text <8pt is recommended to be printed in monochrome []. Guangzhou Jiezhong Supports: Free design review, automatic detection and correction of RGB images and low-resolution files, reducing color difference risks from the source. established in 2009 and located in Zengcheng National Economic and Technological Development Zone, Guangzhou, is a professional manufacturer specializing in the research and development and production of various cards and RFID tags.
