Blueprinting

• Blueprints & Blueline Prints fade rapidly with age, so don't leave blueprints (diazoprints) out in the air or under light for longer than necessary.
• If you have old Blueprints (i.e., white lines on dark blue background) ask XPress Copy to make you a "reverse" (or "negative") copy, which will be much easier to read.
• Because diazoprints are unstable (i.e, they fade), XPress advises you to scan important blueprints and bluelines to digital storage sooner than later.
