yeah thats the schematic I had mentioned..... those are cool, but there is just something about the blueprint that I think is really cool!
Back in the day, blueprints were way cheaper than Xerographic engineering reproductions. That all switched a few years ago, where now the Xerox copies of full sized prints are far cheaper than traditional blueprints (which can still be had, BTW, from any well stocked reprographics shop). They tell me that it takes time to get the blueprint machine set up and the chemicals are getting costly, as well as the special paper used to develop the print.
Here's a simple way to make your own in your computer blueprints (I use Photoshop Elements):
1. Import the drawing into Photoshop (or your main photo imaging application).
2. Make sure the drawing is set as a RGB color drawing in the top menu under "Image." Internet images are often already set as "RGB" (Red, Green, Blue) already, but there is the possibility that a black and white image will be set to "Grayscale."
3. Take your Photoshop "Enhance" drop down menu and set the contrast slider so the lines in the drawing are very light gray. Set the "Enhance" menu again to "adjust color" and add some blue until it "looks good" to you. Open the brightness/contrast again and up the contrast to "take away the gray" and darken the lines again--they will now be darker blue lines.
As a matter of fact, a blueline is the correct term for a blueprint that has been rendered as a standard drawing where the paper is white and the lines are blue. If you want the traditional style of a dark blue background (called a white line drawing) drop down the "Image" then "Adjustments" and select "Invert." It will render the drawing as a negative form, what was once dark blue is now white and vice versa.
4. If you also either imported or resized the drawing to poster size, you can take the computer file on a CD-Rom or whatever to the reprographic shop and they can copy on large size paper for you. If you're framing a smaller size that's common on most home color copiers, just hit "Print."
