What do you mean by blueprinted? Clearances all checked? Or do you mean flow-matched? Mine were flow matched and labeled so that I could put the heavier flowing injectors on the rear cylinders...I've never heard the term blueprinting as applied to fuel injectors.
Blueprinting is a term that is way overused. Basically it means to put something together or to rebuild it according to original specs. In the case of injectors they would repair or replace all parts and flow test to ensure they are within specs when done.

What you are looking for is "Flow Matched" injectors. This insures each injector flows the same so all cylinders receive virtually the same amount of fuel. This is what is important. Also, there are a lot of companies that claim their injectors are flowmatched, but all are not created equal. The % of accuracy is important as is the careful control of the testing conditions. You often get what you pay for.
