Define Precision
At GPI, precision is not a marketing ploy - it is a measurable engineering standard: ±.005”.

Every aeronautical Mylar we duplicate, digitize, vectorize, or plot is held to that standard.
What Precision Means
Before defining Dynamic Accuracy, we begin with the fundamentals.
Precision
The quality or state of being exact.
Accuracy
The degree of conformity to a true standard or value.
Dynamic
Marked by continuous and active function across an entire system.
Dynamic Accuracy
Dynamic Accuracy is the exactness of measurement across the entire surface of an aeronautical Mylar — whether the output is a duplication, plot, digitization, or vectorization.
It is not sufficient to measure correctly between two points. Every addressable point across the Mylar must maintain dimensional integrity.
That is our standard.
How We Ensure Dynamic Accuracy
Accurate Image Capture
We utilize a large-format, glass platen, flat-surface scanning system.
We do not use pinch-roller scanners.
This ensures the original Mylar remains dimensionally stable during capture.
Controlled Output
Our plotting systems are also large-format, glass platen, flat-surface systems.
We do not use pinch-roller plotters.
This prevents distortion during reproduction.
Physical Verification
Every product is measured between established control points and visually compared against the original on a light table.
Dimensional verification and visual confirmation are both required to meet GPI's Dynamic Accuracy standard.
Our Standard
Capture accurately.
Maintain exactness throughout the process.
Verify every output.
The execution is complex — and that complexity is why GPI remains a trusted source for precise duplication, digitization, vectorization, and plotting of aeronautical Mylar.
