Pixelation usually occurs when the image has been either created too small to be enlarged to poster size or has been compressed when saving the file
We suggest that your image file (tiff, jpg or png) is more then 450kb in size as we have found that anything smaller than this could be pixelated when enlarged up to poster size especially if the poster contains text.
Most digital cameras now take files that are much larger than 450kb so should be fine for poster prints. If you are creating the file yourself please ensure that the quality is large enough to be printed at full size. Also if the file is being sent via a mobile device please ensure that the attachment isn’t being compressed when sent.
