Is it necessary to upload signature with black ink pen during filling JEE mains 2020 application form, signature with blue is not valid?
Hello dear aspirant .
For your kind information if you have uploaded signature in blue ink pen then no problem it is ok. But yes it is advised that you should use black pen in such cases as omr scanning machine reads Black colour easily at the time of scanning. But it is also ok with blue ink pen.
Ok good luck
