When printing large format files, most people use the wrong resolution. The image’s resolution does not have to be as high compared to magazines or other print material as it’s based on how close you are looking at the printed item. You fail to realize that the images will be viewed from a greater distance. Most people put much more importance on the size of the print out than is required because what matters is how far the image will be viewed from. There are a few things you should consider when deciding what resolution to use for your large format printing. The most important to remember is the purpose for which the images are to be used. Here are a few tips from the Vancouver large format printing experts at LinxPrint to guide you when deciding the right resolution for your large format print outs.
Look at the document bleeds
If the project/print out is getting finished with grommets for mounting, you need to leave at least two inches in between your live area and the trim. The usual or rather common 0.125in terms of bleeds apply only for wide or bigger format printing.
Consider the color space
Even though you’re preparing lower resolution files than you normally use, make sure the images are CMYK. This can really effect how correct the color of the image is when printed.
Graphic image resolution
The viewing distance greatly influences the file setup and quality of the image. When an image is created for large dimensions, the raster images will be enormous. Transferring this image via email and file transfer will take far too long. Plus, the larger the image is, the harder the processor on the computer has to work to render the image.
Work at a percentage that is scaled
When it comes to large format design the maximum dimension is 216 inches in dimension for either side. Maximum dimension is a little larger, in width or height, 227.5 inches is right. At 100 ppi a 120×80 proto inch becomes 60×40 at 200ppi so make your images half of the scale only and the resolution should be doubled for efficient output images prints.
Saving a final print
After you are done with the resolution and specs of preparing the image for a large format printing, it’s recommended to save it in PDF format because this will help in the image compression and hence make the management more efficient.
You need the right PPI in order to make the right printings. In artwork when it’s practical, PDF print outs or other format are more practical and easy to print. They have a fixed resolution. Your general workflow is to produce elements in large format printing outputs as TIFF files.
If you don’t use the right resolution for large format printing the end result will be a fuzzy low quality print out. If your image resolution is not watched, you may have to create a completely different design from scratch. It’s more important to have the right quality of image, one that the viewers will appreciate and that will have the desired effect that to have a large fuzzy image that will not be viewable or easy to make out. In the long run, image quality matters more than image size.
