Why isn’t the PDF less than the print version for non-print purchasers?
The content is the most valuable aspect of the book, which remains the same in print and in PDF format. The uniqueness of the PDF required additional expenses (some of which are on-going) that were not included in the print edition.
Can I print from the PDF?
Yes, but there is a limit to the number of times you can print from the file as a single user purchaser. The maximum is 50. Each time a page, range, or group of page ranges printed counts as one printing.
Can I Modify the File?
The PDF cannot be edited, nor does it allow you to cut and paste the text. If you have additional questions about the Lighting Handbook not addressed here or if you are having trouble downloading the PDF, contact email@example.com or call 212-248-5000, ext 112.
What do I do if my download was not successful?
If you are able to open the PDF but see blank pages, we recommend that you uninstall the Acrobat Reader and re-install it (For PCs go to Control Panel, then Add/Remove Programs).
If you are unable to access the PDF, there was a problem with verifying your user name and password. Please call 212-248-5000, ext 112.
What do I do if I can access the PDF but I can’t print?
Try unchecking the box in Acrobat Reader X at Edit>Preferences>General> and select Enable protected mode at startup and try to the print job again.
