Hello, this is ok, but it is more common for your works to be printed in yin and yang. In fact, it is also possible if you only cover a positive seal. There are also many calligraphers who put their works on Yang. The ultimate principle of our art is that the overall effect of the work is the best. According to the picture requirements of your calligraphy works, if your works are stamped with the front print, they can be stamped. We should be artistic for the overall effect and adopt different means.
I hope it can help your artistic creation!
If you still don't understand, you can keep asking, please give me more advice, hehe.
