Detailed explanation of the causes and solutions of printing color difference
🎨 What is chromatic aberration?
Chromatic aberration, as the name suggests, is the difference in the color of the same picture on different carriers. This is often the case between screens and between electronic pictures and physical prints.
🌐 The concept of color chasing
Color chasing can be understood as using various means to adjust the color to be similar to the reference color according to a certain reference color. The goal is for you to get a relatively satisfactory color, not a perfect reproduction of the file's color.
🔍 Reason 1: The color mode of the file is different
Different file color modes are one of the main causes of color aberration. Here's the detailed analysis:
Difference between the color of the screen display and the actual print: The color displayed will vary depending on the screen material and internal settings of different displays. The color mode on the screen is RGB mode, and most printing machines will automatically convert the RGB mode to CMYK mode when printing, resulting in color differences.
Printing machine default mode: Not all printing machines use CMYK mode by default, please consult the factory for related printing of RGB mode.
🛠 Solution:
When creating a canvas, the CMYK mode is set in advance.
Drawing with the CMYK color mode reduces the sense of color difference when the physical product is printed.
📊 RGB mode vs. CMYK mode
RGB Color: Vivid colors will be more vivid in RGB mode.
CMYK Color: In CMYK mode, the color will become gray.
📸 Comparison of examples
RGB source files: Vivid colors.
CMYK source file: Gray color.
Actual photos: Colors are somewhere in between.
From the above analysis, we can conclude that in order to reduce the color gap during physical printing, it is recommended to set the CMYK mode when creating the canvas and use the CMYK color for drawing. This can better reproduce the color effect of physical printing.
