Generating Actual-Size Copies of Watermark Prints

Screen images of watermarks -- the images generated by your graphical WWW browser or by a "helper application" like JPEGView (used on Macintosh computers) or LView Pro (used on PCs with Windows) -- may not appear accurately sized for matching against the watermark tracings or contact prints which you may have made from the manuscripts or documents that you are studying. Nor are all WWW browsers and their helper applications able to print up a copy on paper which is accurately sized.

To match your own tracings or prints against watermarks preserved in this archive, you will need to print out on paper accurately sized copies of the comparable watermarks found in this archive. These images do preserve the necessary electronic information to generate actual-size paper prints. Therefore, it is easy to generate an accurately sized print from this archive using a full feature graphics program like Adobe Photoshop.

To produce actual-size paper copies for comparison with your own watermark tracings, follow these four steps:

  1. First save the watermark image (which your WWW browser has downloaded for on-screen viewing) by using the "SAVE AS SOURCE" option. Do NOT use the "SAVE AS TEXT" option!

  2. You will then load the saved JPEG image into a full feature graphics program like Adobe Photoshop.
    This and other such programs are capable of both printing the image, and utilizing the electronic information preserved in the JPEG image to reproduce the image on paper at the actual size of the original watermark.

  3. To generate an actual-size copy on paper, you must set the resolution at which the image will be printed to agree with the resolution at which the original was scanned, using the commands menu in your graphics program. (The scanning resolution we have adopted as a standard for this purpose is 400 DPI.)

  4. Next, constrain the file size and image size.
    These constraints are to prevent your graphics program from adjusting the printed image to the full size of the paper (image size constraint) and to prevent it from altering the data preserved in the electronic file (file size constraint).

You will now be able to print an actual-size reproduction of the watermark simply by using the "print" command in your graphics program.
