      A method of enhancing a footwear impression formed on a porous surface using a potassium ferrocyanide solution for footwear impression enhancement includes: forming a porous surface sample by leaving footwear impressions into an object having a porous surface; preparing a potassium ferrocyanide solution for footwear impression enhancement; and applying the potassium ferrocyanide solution for footwear impression enhancement to the porous surface sample.
    • Claim:
      1. A method of enhancing a footwear impression formed on a porous surface using a potassium ferrocyanide solution for footwear impression enhancement, the method comprising: forming a porous surface sample by leaving footwear impressions into an object having a porous surface; preparing a potassium ferrocyanide solution for footwear impression enhancement wherein the preparing of the potassium ferrocyanide solution includes mixing an aqueous solution of potassium ferrocyanide and hydrochloric acid; and applying the potassium ferrocyanide solution for footwear impression enhancement to the porous surface sample.
    • Claim:
      2. The method of claim 1, wherein the preparing of the potassium ferrocyanide solution for footwear impression enhancement comprises: preparing the aqueous solution of potassium ferrocyanide by dissolving potassium ferrocyanide in water.
    • Claim:
      3. The method of claim 1, wherein the applying of the potassium ferrocyanide solution for footwear impression enhancement to the porous surface sample comprises: uniformly spraying the potassium ferrocyanide solution for footwear impression enhancement on the footwear impression left on the porous surface; removing harmful gases that occur in the porous surface sample; and applying heat of an enhancement condition temperature to the porous surface sample for a certain time.
    • Claim:
      4. The method of claim 2, wherein, in the preparing of the aqueous solution of potassium ferrocyanide, the water for dissolving the potassium ferrocyanide comprises deionized water.
    • Claim:
      5. The method of claim 2, wherein, in the mixing of the aqueous solution of potassium ferrocyanide and the hydrochloric acid in a certain ratio, a mixing ratio of the aqueous solution of potassium ferrocyanide and the hydrochloric acid is 1:1 by volume.
    • Claim:
      6. The method of claim 2, wherein a concentration of the aqueous solution of potassium ferrocyanide is in a range of 9.5% to 10.5%, and a concentration of the hydrochloric acid is in the range of 0.9 M to 1.1 M.
    • Claim:
      7. The method of claim 1, furher comprising: heating the porous surface sample to which the potassium ferrocyanide solution is applied at a temperature of 100° C. or higher.
    • Claim:
      8. The method of claim 7, wherein the porous surface sample to which the potassium ferrocyanide solution is applied is heated in a range of 100° C. to 130° C. or in a range of 170° C. to 190° C., for 10 seconds to 20 seconds.
    • Claim:
      9. The method of claim 7, wherein the porous surface sample to which the potassium ferrocyanide solution is applied is heated for 10 seconds to 20 seconds.
