A method of printing precision being improved by surface imbibition characteristic, this method is led for typographical display in the present embodiment
Domain.First, easy wetted area and non-infiltration regional graphics are prepared in substrate surface according to printing information, the wellability in two regions is poor
It is different be mainly reflected in printing ink the two regions contact angle size；In tradition, the contact angle of material surface is less than 90 °
With easy imbibition characteristic, the contact angle of material surface is more than 90 ° for non-infiltration characteristic.Due to the difference of contact angle, printing
Ink is easy to contact with easy wetted area, and extremely low in non-infiltration region adhesion.The present embodiment by taking a certain pixel unit as an example,
