MANY VISION LOSS CONSUMERS ARE FAMILIAR WITH THE BENEFITS OF EASIER-TO-SEE NEGATIVE VIDEO DISPLAYS: CCTV ELECTRONIC MAGNIFIERS AND COMPUTER SYSTEMS THAT CONTROL BRIGHTNESS WITH WHITE-ON-BLACK MONITOR SCREENS.

A. EXISTING PAPERWORK

THIS SAME HELPFUL READING ASSISTANCE FOR LOW VISION INDIVIDUALS CAN ALSO BE USED WITH HARDCOPY.

SPECIFICALLY, TO ELIMINATE THE GLARE OF WHITE PAPER, A COLOR COPIER CAN PRINT IN REVERSE TO PRODUCE THE NEGATIVE EFFECT OF WHITE LETTERING ON A BLACK BACKGROUND. GENERALLY, LETTER-SIZE COLOR COPIES COST ABOUT A DOLLAR PER PAGE. ALSO, BE SURE TO SPECIFY A MATTE FINISH TO AVOID PAPER REFLECTIONS.

FOR REFERENCE, THE PHONEBOOK YELLOW PAGES HEADING FOR PLACES THAT DO COLOR PRINTING SEE - COPY AND DUPLICATING SERVICE.

B. COMPUTER PRINTING

FIRST, IT IS IMPORTANT TO REMEMBER THAT A NEGATIVE-IMAGE MONITOR SCREEN IS ONLY A DISPLAY GLARE FILTER AND DOES NOT CHANGE THE ACTUAL COLORS OF THE MAC OR PC TEXT AND GRAPHICS, WHICH REMAIN A POSITIVE-IMAGE.

UNDER THE CURRENT OPERATING SYSTEMS FOR BOTH APPLE MACINTOSH AND MICROSOFT WINDOWS, THE OPTION OF RUNNING A NEGATIVE-IMAGE DISPLAY IS BUILT-IN. HOWEVER, OLDER OPERATING SYSTEMS MAY REQUIRE THE USE OF A THIRD-PARTY SCREEN MAGNIFIER SOFTWARE, SUCH AS inLARGE FOR MAC AND MAGIC FOR PC, TO REVERSE A POSITIVE-IMAGE DISPLAY TO WHITE-ON-BLACK.

SHOULD A LOW VISION CONSUMER WANT TO PRODUCE NEGATIVE-IMAGE HARDCOPY FROM THEIR COMPUTER AND BLACK-AND-WHITE PRINTER, FIRST CHECK YOUR WORD PROCESSING APPLICATION TO SEE IF IT CAN CREATE A WHITE-ON-BLACK FILE. OTHERWISE, ANY DATABASE PROGRAM CAN BE USED TO SET-UP A SPECIAL FILE FOR NEGATIVE-IMAGE PRINTING:

1. FROM THE DATABASE PROGRAM CREATE A NEW FILE WITH TWO RECORDS, EACH DESIGNED FOR A FULL-PAGE-IMAGE

2. THE FIRST RECORD IS THE PASTE-IN WINDOW FOR A POSITIVE-IMAGE DOCUMENT

3. THE SECOND RECORD IS THE NEGATIVE-IMAGE PRINT-OUT WINDOW WHICH TELLS THE COMPUTER PRINTER TO DO A COLOR REVERSE

4. THEN COPY A WORD PROCESSING DOCUMENT, GO TO NEGATIVE PRINTING DATABASE FILE AND DO PASTE-IN AT FIRST WINDOW

5. SWITCH TO SECOND WINDOW AND DO NEGATIVE-IMAGE PRINTOUT

6. BLACK-AND-WHITE COMPUTER PRINTER SHOULD PRODUCE A CRISP WHITE-ON-BLACK DOCUMENT

NOTE:

BE AWARE, NEGATIVE IMAGE PRINTING WILL INCREASE TONER CARTRIDGE CONSUMPTION. FOR EXAMPLE, 100 - LETTER-SIZE WHITE-ON-BLACK PRINTOUTS WILL SHORTEN OPTIMAL CARTRIDGE LIFE BY APPROXIMATELY ONE-THIRD.
