But thedigital art design have got what oneself the magic power's art design of the specialkind manifestation, lack the perfect and emollient theories system of oneself over along period of time, and not set up to adapt to the digital art design characteristicwith the development's idea and thought, not these ideas with thought the guideinto to the digital art design's artistic with enjoy the inside and go to, digital artdesign can't break the mode of the traditional art design with old mt, can't developthe advantage of the arithmetic figure to sink into the mimicry with magic power,It is not difficult with plagiary predicaments.

但数字化艺术设计是有着自身独特性质的魅力的艺术设计表现形式，长期缺乏自己完善有力的理论体系，不树立适应数字化艺术设计特征和发展的观念与思想，不将这些观念和思想引入到数字化艺术设计的创作和欣赏中去，数字化艺术设计就无法突破传统艺术设计的模式和窠臼，无法发挥数字化的优势和魅力，难免陷入模仿和抄袭的困境，无法进一步的前进和深入，这无论是对数字化艺术设计本身还是对整个艺术设计的发展都是不利的。
