“Using InDesign for Creating Posters” screencasts available

Our screencast series on designing Posters with Adobe InDesign is now available online. To see them you can go to my YouTube channel (laddrob) or go to the Using InDesign for Creating Posters playlist. There are a total of nine videos. The following is part 1:

Image resolution and print size

The following screencast uses Photoshop, but whatever image editor you use, the concepts are the same:

(1) There is an inverse relationship between print size and resolution (if you increase the print size the resolution decreases and vice-versa).

(2) To get good results when inserting an image into a research poster, the image should be printed at a resolution of at least 200 pixels per inch (ppi).

(3) Images that look good online may not be high enough resolution to look good in print at the size you want them to be.  For example, an image of 640 by 480 pixels may look fine on your computer screen, but printed at 200 ppi it would only be 3.2 by 2.4 inches in size.

Resolution and print size for images

Here is a convenient reference table from http://www.nikonians.org

Resolution & Print Size chart

If you want very high quality you need to print at a resolution of at least 300 pixels per inch (ppi). (Of course, you need to start with a good original image.)

Generally, a resolution of 200 ppi is fine for images to be inserted into posters that will be presented at conferences. 300 ppi is even better, but not necessary.  A resolution of below 150 probably won’t look very good.

So, for example, if you want to insert a 10″ by 7″ photo into a poster, the image should preferably be at least 2000 by 1300 pixels to look good.
