The first rule for printing is always print your final image/piece at 300 dpi (dots/pixels per inch)
The Venngage canvas is automatically set at 96 dpi as that is the standard for screen resolution.
If your export intent is for print make sure you are exporting using PNG HD as this export takes our 96 dpi and multiplies the infographic giving you a final file that is at the desired 300 dpi.
If you export with the regular PNG you may end up with a slightly pixelated version.
PRINTING SIZE STANDARDS
Think about how big you are wanting to print and then make sure your canvas is the correct size. Our measurements are set to pixels so you will want to convert the size into pixels using one of the pixel converters found online. Then you can set your page size in the pixels. (Please see http://support.venngage.com/article/114-how-do-i-change-my-page-size for details on how to set your page size.)
Please note that most standard printers can’t print to the very end of paper (full bleed) no matter what the size is. For example, if the background of an infographic is red and the page is set to letter size, you will end up printing on a letter size piece of paper with the graphic shrunk just slightly. There will be a bit of white around the edges of the paper and this will need to be cut off.
Magazines and poster professionals design and print for the correct size but print on larger paper. They then cut off the excess.
RGB VS CMYK COLOR PRINTING STANDARDS
There may be some variances in colours from screen to print, this is due to screens use RGB and printers use CMYK, and each have their own range of colors that they can produce.
RGB has a much larger range of color so this result in some very vibrant blue’s and very vibrant red’s such as pink on Venngage ending up looking dull in print. It is good to be aware of this when designing on screen and intending to print.
There are many RGB to CMYK color converters. If you think a blue may not look the same then run it through an external converter such as http://www.rapidtables.com/
