What Are the Common Types of UV Inkjet Printing Processes?

Based on the color type, ink layering, and printing method used, common UV Inkjet Printing processes can be generally categorized as: single color, color-on-white, color-on-white-and-color, and color-on-white-and-color.

Single Color Mode

Single color printing refers to printing using only one color ink, usually black or another solid color. It is suitable for printing simple patterns or text and is commonly used in applications such as labels, business cards, and product logos. Single color UV printing offers high printing accuracy, high speed, and low cost. But it lacks the ability to produce rich color effects and has a limited range of applications.

Color-on-white Mode

Color-on-white printing adds white ink to color inks. Because white ink is opaque, it can be printed on transparent or dark substrates, making colored patterns more vivid. This process is commonly used for printing on materials such as acrylic and glass, such as wine bottles and phone cases. Because the white ink is printed first, followed by the color ink, printing speed is slower and the cost is higher than single color printing.

Color White Color Mode (C+W+C)

UV roll to roll printer uses a three-row printhead layout. The first and third rows print color ink, while the second row prints white ink. When printing, select the color white color mode in the software. The color ink is printed first, followed by a layer of white ink, and then a final layer of color ink. This process can achieve complex patterns and color effects and is suitable for items requiring vibrant patterns. For printing on transparent or irregular surfaces, a base of white ink can enhance the color’s expressiveness and coverage. The printing process involves multiple ink layers, resulting in longer printing times, greater difficulty, and relatively high costs.

Color White Black and White Color（C+W+B+W+C）

This process is an upgraded version of Color White Color. In addition to the standard color and white inks, black ink is added. The use of black ink enhances the design’s appearance, especially against dark backgrounds or transparent materials, creating richer color depth. This process is suitable for designs requiring a higher level of detail and contrast. It is commonly used in high-end custom products, artwork, and delicate industrial parts, particularly for better reproduction of intricate pattern details.
