A sign board is a display of name / logo of the business placed on top of a store, it helps existing customers in locating a store. For new shoppers, looking to buy products that you deal in, the sign board can act as an invitation. How strong the pull of the invitation is, depends on the quality and attractiveness of the signage when compared to competitors around you. Thus, signage board design acts as a strong factor.
Choice of color and impact on illumination and visibility:
The colors used for sign letters, objects, and background greatly impact the sign board’s visibility. In a study, the following color combinations were ranked from most to least readable.
Also when going for a lighted signage, the impact of the color on lighting also needs to be considered. Different colors behave differently to illumination. When you have planned to go ahead with an in-lit signage, then you should be aware of the behavior of the color of sheet being used to the lighting. More illumination typically leads to more visibility. While creating the signage board design, this has to be given high priority, since the lighting won’t have the right impact if not combined with optimum color.
Percentage of light reflected by various colors:
In case a store is located in a market setting with a lot of stores, then in order to maintain the visibility, you should choose a light color for the signage. But, in case of no or very low competition around, even a dark color signage can work while keeping a premium and commanding presence.
Mathematical Analysis to finalize sizing of artwork
For calculating best possible visibility, in terms of positioning, the below analysis needs to be done:
The following formula can be used to find the minimum size (height) of the lowercase letters that can be used in the signage board design which is visible to the viewer.
Here, R – reading distance (in meters) and X – height of lower case letters.
Considering the following case:
In the given image, the products written at the bottom of the signage are not clearly visible. For the given store, if the width of the street is 5 meters, then, for every element of the signage to be visible through the width of the street. Using the above given formula, the minimum height of lowercase letter should be:
X = 5/200 = 2.5 cm
The final results tell us that, once the sizing of the sign-board is finalized, and the designers work on the artwork to be used. In-order to maintain proper visibility even the smallest of elements in the signage board design need to be at least 2.5 Cm in height.
