Seals can be enjoyed in their own right, but when affixed to calligraphy or a painting they can provide that final touch which balances the work perfectly and so contributes to the overall effect. Of course the size of the seal, its position and its inscription always need to be complementary to the work in question.
印章固可單獨欣賞，但在書畫是「賓客」地位，擔負畫龍點睛、平衡畫面，以及為書畫增色的功能，所以用印的大小、位置及印文內容，都要能與作品有相輔相成之效。
