I have a minimum and a maximum square foot price. Currently it runs from a maximum of $24.00 to a minimum of $6.00. Just where any particular job ends up on this spectrum depends entirely on the size of the job. I use a formula that reduces to...
minimum+(maximum-minimum)/(total image area)
This formula becomes asymptotic about the minimum charge, which in English, means that the larger the job the closer to the minimum it gets but it never actually gets to the minimum.
For example, for 100 3x4 decals the total image area, including spacing, would be ~10 square feet. By the formula the price per square foot would be 6+(24-6)/10 or $7.80 per square foot. This is just the printing charge, the charge for the linear feet of media unrolled for this job is added to this as well as lamination, if any.
This generates a pleasing curve where the large the total image area the closer to the minimum square foot price. This has the added charm of automatically adjusting for large volumes of small objects and divorcing the charge for the media from the charge for the printing.
