The “white channel” of a UV printer?

In the field of digital UV printing, the setting of the white channel is a key step. 

Especially when dealing with graphics that require a white background or printing on transparent, dark materials, or need to print relief, 3d embossed effect.

Correctly setting the white channel can not only ensure the vividness and clarity of the printing effect, but also improve printing efficiency. 

Now we will discuss in detail the setting method and importance of the white channel in UV printing. 

The role of the white channel

1、Provides an underlayer white: When printing on transparent or translucent materials, the white channel can act as an underlayer to make subsequent color prints more vivid. 

2、Increase covering power: For materials with dark backgrounds, the white channel can effectively cover the original color and ensure the accuracy and saturation of the pattern color. 

3、3D Relief effect: When printing 3d relief embossed effects or patterns that require a sense of hierarchy, the white channel can enhance the 3D and layered sense of the pattern. Make your printing effect more unique and attractive.

How to set the white channel?

1、Choose the right white ink: Choose the right white ink based on the printing material and needs. Different inks vary in hiding power, drying speed, etc.

2、In Photoshop, select the area in your image where you want to print white ink (equivalent to the area where you want to print the relief), create a white channel and save it, then import the image into the printing software.

3、Test printing: Before the formal printing, do a small test print. By constantly adjusting the parameters of the white channel, find the best setting.

4、Monitor the printing process: During the printing process, pay close attention to the performance of the white channel. If problems are found, such as clogging, uneven ink jetting, etc., adjustments should be made in time.

Precautions：

1、Keep the print head clean: Clean the print head regularly to ensure that the white ink can spray smoothly.

2、Keep communicating with your supplier: Different printing materials and inks may require different white channel settings. Keep communicating with your supplier to get professional advice and technical support.

Mastering the setting method of the white channel in UV printing is crucial to improving the printing effect. Through reasonable settings and adjustments, we can not only obtain more vivid and clear printing effects, but also be more comfortable in dealing with various complex printing needs.
