Two Common Toning Techniques for Digital Printing

Color palette method Color palette is a method of mixing colors by comparing the colors in the color card. The basic process is: first, the establishment of the color card model. One or more color modes can be selected to establish the color card model, which is a three-dimensional (Lab mode and RGB mode) or a set of three-dimensional (CMYK mode). Next, make color card files. The 3d model can be decomposed into 2d graphics, with one of the values as the variable, and for CMYK mode, there are two variables. After making the color card file, print it out for later use.

This method is simple and easy to use, just to compare the target color with the color card, and to choose the same color. However, using this method may make different fabrics produce color differences, so the color card fabric should be the same as the target fabric. Besides, the three - dimensional scale subdivision of the color card will also affect the color mixing effect. The too fine-scale will greatly increase the number of color cards and the workload of comparison; if the scale is too large, the number of color cards can be controlled, but we may not be able to find the desired color during the comparison.

Colour measurement method

This method uses a precision color tester to measure the color of the target color block, and input the result into the computer, and then print out the color. This method uses a precision color tester to determine color, thus eliminating many human and environmental factors.

When using this method, the sensitivity and accuracy of the precision color tester itself have a great impact on the measurement results. If the measurement results are not accurate, it will directly affect the printing effect. On the other hand, fabric texture will also affect the color measurement.
