Lace plays a role in separating and beautifying the layout of blackboard newspaper. It can make the layout clear, dense and alternating, and will not cause mixed articles and mutual interference. In addition, it also plays the role of connecting all the components of the layout and making it a unified whole. At the same time, it can also set off the ideological content of the article and achieve the purpose of adjusting and decorating the layout.
Lace is called "double-sided continuous pattern" in design jargon. It is a strip pattern with one or several unit patterns regularly arranged between two parallel lines and continuously unfolded in the left-right or up-and-down direction. If the pattern arranged continuously develops in the left and right direction, it is called horizontal bidirectional continuity; If the patterns are arranged continuously from top to bottom, it is called longitudinal bidirectional continuity; The end-to-end circular arrangement is called a double-sided continuous frame.
Lace has the beauty of rhythm and rhythm in form. Its composition includes: scattered type, horizontal type, vertical type, diagonal type, broken line type, wavy line type, continuous loop type, combined type and so on. When the blackboard newspaper uses lace, its pattern should be related to the decorative article as much as possible, so that readers can feel the meaning or content of the decorative article. If the article reflects the content of tree planting and greening, lace can be continuously expressed in patterns composed of leaves or saplings. Of course, the decoration and beautification of lace is not necessarily related to the content of the article. We should use it flexibly according to the layout, and make more changes and innovations. Various patterns can be used for reference and used as lace to make decoration and beautification more innovative and aesthetic.
The drawing of blackboard lace should pay attention to the balance and symmetry of the pattern, the same size and simplicity. The layout must be coordinated with other parts of the blackboard newspaper and must not be misused. Otherwise, the layout will look crowded and fancy.
