Thanks very much. I've been trying to explain the resolution issue to them. I spouse shrinking them to up the effective resolution is an option: they don't all need to be full screen size in the page layout.

Dear Daniel

Given that you are taking screen shots, the optimal way to do this on Windows would be using CTRL+ALT+prt sc which will capture the current window in focus to the clipboard and then you can cut and paste this to an imaging program such as Photoshop, the full version of Acrobat which allows you to “create a PDF from the clipboard” or something similar. If you have Google Picasa3 running in background then it will pick up the fact you have captured a screenshot to the clipboard and will allow you to manipulate it. Mac has its own equivalents and utilities for these sequences. See: http://guides.macrumors.com/Taking_Screenshots_in_Mac_OS_X I would recommend against using a digital camera to photograph a display because you will have an inevitable drop in quality of the final image compared to a screen grab.

However, the thing to appreciate is that screen resolution is very low compared to print resolution and depends on both the horizontal and vertical resolution as well as the screen size. For example a typical wide laptop screen with a resolution of 1600x900 would equate to only around 72dpi on a screen grab. You will find this website useful in terms of telling you what your effective dpi is when you do a screen grab on your computer: http://members.ping.de/~sven/dpi.html

If your publisher is saying they need 300dpi TIFF for screen shots, then it may just be that they don’t understand what you want to achieve. However, it is certainly possible to achieve this by decreasing the physical size of the image. As one example, a 1600x900 pixel screen grab image off a 22”x12.5” laptop display equates to ~72dpi. Change the image size to 300dpi in Photoshop (use constrain proportions and do not use resampling) and this gives you a 5” x 3” image. This might seem a bit weird at first but probably the best way to think about this is that you are fitting more pixels into a smaller area which would probably suit an A5 (or USA equivalent) size page.

Probably the best thing to do initially is just to do a screen grab, convert it to a TIFF or PDF using any one of the many utilities that exist to do this and then email it to the publisher and see what they say. You’ll probably find they also accept JPG. Most publishers do.

Hope this helps.

Hi all,

I have a tangential topic: what is normal practice regarding screen shots in print and PDF?

I have an article coming out and the production manager wants 300 dpi TIFFs for my images. But the images are for the most part screen shots and, since I'm talking /about/ navigation and representation issues in virtual environments, I can't go with the second option they offered me:

giving URLs rather than presenting that actual images in the text.

I'm sure I've seen screenshots in both print and PDFs before. What is normal practice?
