As we all know, whiteboard has a characteristic that the surface is white and smooth. At this time, Jianyue will pay attention to many problems when printing whiteboard, so as to produce whiteboard with this characteristic. The following contract describes how to prevent the whiteboard from sticking.
First of all, when printing the full version on the spot, try to use the original barrel of ink without 6# adjusting ink, add anti adhesion agent appropriately, and do not add dry oil when the weather is hot. It is easy to dirty the back of the printed full plate on the ground. At this time, Dongguan gray board paper manufacturer proposed that it should be solved by powder spraying. The antifouling powder spraying agent of printing whiteboard contains pure plant materials with good dispersion and fluidity, but the use of powder spraying agent directly affects the surface gloss of printing products, the ink color is not bright, pollutes the environment and affects the accuracy of offset press.
Secondly, due to the rough surface, loose quality, large ink absorption and poor flatness of the whiteboard, the contract proposes to print the background color first and then the dark color. The background color is deep and thin, and the ink color shall not be too large. If the flatness of the whiteboard is good, you can first print the dark color with sufficient ink, based on the non stick dirt on the back, and then print the background color thinly, so that the smoothness of the printed product will be better. At the same time, pay attention to the water ink balance and control the water content of the printed layout.
The above is how to prevent the whiteboard from sticking and dirty during production introduced by the contract. The contract has been introduced in two aspects. I hope it will be helpful to you. If you have any questions, please contact us!
