Will compressed files invariably lead to bad print results? Charlie Facini explores the origins and implications of JPEG compression
The .jpg format was originally developed to minimise the size of photographic image files for transport at a time in the 1990s when the Internet had very low bandwidth, and not for production use.
If accepted, the full quality image was then shipped via a more traditional method, ensuring the best print result.
Never intended to be a format used with images destined for print, it was meant to be a thumbnail or reasonable representation of the higher quality original image that could be e-mailed through a slow Internet.
So, why is the .jpg format used often and widely today in all print industries, including screen-printing, when quality is lost?
