SafetySign.com’s advanced printing process undergoes a stringent cross-hatching test. This specifically tests the adhesion and resistance to separation of the inks from the sign. In testing, a sample from the printing process is scored and covered in adhesive tape. The tape is removed and the sample assessed for adhesion quality.
We use a three-stage process to test all of our printing processes. We print our signs using only the processes that pass all three stages, giving you the highest quality signage possible.

The text is printed in HGCPIXymbols and HGDPIXymbols fonts.
The Slow Speed Bump Sign from SafetySign.com uses these fonts because the message requires a font that will allow it to fit on the sign. These fonts are easy to read in daytime and nighttime conditions, and they are still legible no matter what version of the typeface is being used on the sign. They are also used to keep a consistent look with other traffic and parking related signs from the MUTCD.
