I was asked to design a series of interactive wireframes using Axure for client who wanted to see how we would approach a design process. I made the designs in grey scale in relatively medium fidelity but I was strongly recommended by some other designers that I should make the wireframes as pixel perfect as possible (even though we are using placeholders and no color). I am a little confused about this since the concept of wireframes is to quickly show a proof of concept and to drive the thought process.
I do understand a clean and well designed wireframe is pleasing to the eyes and might have a more positive response,but the challenge is that making it so pixel perfect\precise involves as much time as creating a visual design and I dont want to get into the trap of users thinking that this is the final shell upon which color has just be applied and then the design is complete.
So my question is that is there any real advantage in making wireframes pixel perfect and where are those specific cases.
I did look at the questions How much detail in wireframes? and Using color in wireframes…is this a “no no”? but they dont answer the question I have.
Edit: Well what I meant by pixel perfect was like perfect alignment,ensuring the grid contents have exact spacing on each side and we are using the exact icon sizes which would be used in a mobile space
