“Quality means doing it right when no one is looking.” – Henry Ford

It today’s digital age there are tons of file format conversion software tools out there that will convert practically any form of digital file between any desired format. However, one key point to keep in mind is that all conversions are not created equally, especially when it comes to quality.

One measure of quality for data or image conversion is the concept of lossless and lossy conversions. As per the Wikipedia definition,

A lossy data conversion method is one where converting data between one storage format and another displays data in a form that is “close enough” to be useful, but may differ in some ways from the original.

On the other hand, a lossless conversion has zero loss of information, it’s by all practical measures a perfect copy. Is some cases, if the original version is somehow compromised in condition, quality or errors, a high quality conversion can also be restorative in nature and correct such imperfections.

How good is “close enough”?

One example that many people are familiar with is the lossy compression that often accompanies when working with or converting JPEG images. The differences in the photos below may have negligible awareness or impact depending on the purpose, but not in all cases.

In the realm of technical drawings and documents for commercial / enterprise / construction purposes, the fine details can be of significance.  Automated software conversion tools have little to no quality control. The output is driven strictly by the input, and garbage in will mean garbage out. Even if the input is of reasonable quality, the barriers to go from raster, vector and fully composed 2D or 3D line/shape drawing are typically well beyond the capabilities of even the most advanced boxed software.

Without a skilled-human review and insight applied to the conversion process throughout, software tools alone are unable to evaluate to what degree the fidelity of the available information is retained and where improvements are needed to ensure not just a lossless conversion and that the output is fit for purpose.

The drawing conversion at DCM uses a proprietary 8-point quality control process to ensure that each drawing is fine-tuned. Drafting principles, CAD standards and your specifications are all taken into account. A Production Manager review the drawing to ensure its complete and ready for immediate use.
